Wildflower Wednesday: Phacelia bipinnatifida and Love at First Sight

 It really was love at first sight.  

Who could resist the lavender-blue flowers with deeply divided, mottled fern-like leaves that bloom in early spring and attracts bees? Those leaves alone are worth having in your garden. They have lighter, grayish-green, or silvery, watermark-like blotches and can develop a purple tinge in late fall/winter. 

My little naturalized colony at its best

It's been so long ago that I can't remember when I added Phacelia bipinnatifida to the garden but, I remember quite clearly the first time I saw a naturally occurring colony on a shady damp hillside. I was going to visit a new friend's garden and was driving up her steep drive, as I turned a bend in the drive every where I looked Purple Phacelia was blooming and bees were dancing from flower to flower. There's something splendid about natives that mass naturally, and this was a dazzling and magical pollinator show.

My little Phacelia colony waxes and wanes from year to year. Purple phacelia/Phacelia bipinnatifida is a biennial wildflower in the Hydrophyllaceae (Waterleaf) family that is native to the southeast USA. Biennials require two growing seasons to complete their life-cycle. The first year is vegetative growth; the second year, they flower and produce seed and shortly after, they die. They're usually quite prolific and will set seed, but, you'll only have flowers every other year. If you want to have blooms every year, you've got to put a little bit of effort into making that happen.

 

Let's get more detailed about what that effort looks like.

When you are trying to get a biennial established it's important to remember: One year from seed, second year to flower, then it dies. To have flowers every year you have to get a colony started, so you need seeds, first year plants and flowering plants. I really was lucky to be given several plants in bloom and many first year seedlings. Here's how it works! Those first flowers were visited by Bumble bees and other pollinators and got fertilized, they set seed and then died. The fallen seeds germinated and over wintered; the following spring the original first year seedlings bloomed and their flowers were fertilized, set seed, and then died. It's not a complicated process, but it's a brilliant cycle that continues to this day.  

 

I make sure the cycle is not interrupted. Which means that I collect the seeds, and sprinkle them where I want new plants, sometimes I move the tiny seedlings, the first year plants and even the second year plants in late winter to make the colony larger. They always seem to survive!

 

If you're lucky it forms self seeding colonies that are simply stunning. 

 As all gardeners know, some years are better then others and this is a lean year. Lean because we've had a several years of low rainfall right when the seeds need moisture to germinate. I've watered enough so that I have flowers every year, but, I will be doubling my efforts this year to reinvigorate my little colony. To insure  the  colony will make it through the deluge/drought pattern Middle Tennessee has settled into, I'll hand water them during the severely dry times.

Bees and other pollinators that are out and about on warm days love Phacelia. It has wildlife value and supports  the following specialized bees: Andrena (Micrandrena) lamelliterga, Andrena (Euandrena) phaceliae, Hoplitis (Robertsonella) simplex.

I am honestly not disappointed that it's a lean year. Especially when I see proof that it's  providing for a lot of early spring visitors. I don't have hillsides of Phacelia, that requires much moister soil than I can give it, but, where it's blooming it shines. 

 

 To successfully grow our Wildflower star give it part-shade, shade, moisture, (it can take some dryness) in acid, neutral, average loam. It won't turn it's noise up at rich moist, well draining soil! 

 There are a few online nurseries that sell Purple Phacelia just do a web search. Or if you're lucky and can find a friend with seedlings to share, you can start your own journey to having a colony of flowers that pollinators adore. I hope that post like this open eyes to the beauty of Phacelia. 

 

 The Particulars

 Botanical name: Phacelia  bipinnatifida

Common names: Purple Phacelia, Fernleaf Phacelia, Fernleaf Scorpion Weed, Spotted Phacelia, Loose-flowered Phacelia

Family: Hydrophyllaceae (Waterleaf) family, also sometimes classified in Borage family

Life Cycle: Biennial

Distribution: AL , AR , GA , IA , IL , IN , KY , MD , MO , MS , NC , OH , PA , SC , TN , VA , WV

USDA Plant Hardiness Zone: 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b  

Height: 1 ft. 0 in. - 3 ft. 0 in. 

Width: 1 ft. 0 in. - 3 ft. 0 in. 

Light: Dappled Sunlight (Shade through upper canopy all day) Deep shade (Less than 2 hours to no direct sunlight) Partial Shade (Direct sunlight only part of the day, 2-6 hours) Full sun if mesic soil.

Soil:  Adaptable-clay, shallow rocky, loamy, sandy and/or high organic matter. PH acidic and neutral. Moisture-well draining and moist  

Flower description: Racemes of 4-12 blue to purple flowers are produced from March through April/May. Individual flowers are 1/2 inch across cup shaped with 5-lobed corolla, 5 sepals, 5 stamens, a slender style, and an ovary. The racemes occur at the top of stems with some secondary ones forming in the axils of the upper stems.  

Color: Blue/Purple/Lavender  

Bloom Time: Spring. March in middle Tennessee.

Propagation: I collect seed by placing a tray with potting soil under the blooming flower. I let most self sow. Seeds ripen shortly after blooming. I let natural rain fall water the seeds and they germinate when temperatures cool in the fall and through the winter. I usually don't notice seedlings until March. Some folks say that the seed needs to be sown fresh, but I am going to try to collect it and place in the refrigerator to see if it will grow when sown later.

 

Surface sowing is always successful and in my garden fallen leaves don't seem to keep them from germinating, so prehaps light isn;t a requirement.

Wildlife Value:  Phacelia support the following specialized bees: Andrena (Micrandrena) lamelliterga, Andrena (Euandrena) phaceliae, Hoplitis (Robertsonella) simplex.
   
Comments: Deer and bunny safe. This is a plant that should be in every shady garden. Find a friend who will share a few seedlings. Phacelia bipinnatifida should be allowed plenty of room in a naturalistic, woodland setting to move around as it wishes. If you want to maintain it in precise spots, transplant seedlings in the fall to preferred locations. 

My thoughts: When it comes to wildflowers almost all the attention centers on perennials. They're marvelous investment plants that you can count on to make a good show in your garden year after year, but, you might want to consider adding a few annuals and biennials that are native to your part of the garden world. They're charming plants and add another dimension to the garden~many of the seedlings and first year plant's foliage is quite attractive. (Gardeners, Do Yourself A Big Favor)

Welcome to Clay and Limestone and Wildflower Wednesday.  This day is about sharing wildflowers and other native plants no matter where one gardens~the UK, tropical Florida, Europe, Australia, Africa, South America, India or the coldest reaches of Canada. It doesn't matter if we sometimes share the same plants. How they grow and thrive in your garden is what matters most.

First Wednesday Taking Care of Wildlife Challenge: I Challenge You To Use Find a Use for Tree Debris

 

 Dear Middle Tennesseans affected by ice storm Fern,  I challenge you to find a use for some of the twigs, branches and tree trunks that are all over your neighborhoods and yards. Although the ice storm was in late January there are still piles of tree debris on many streets. 

 

 

To Recap what happened in Nashville and much of Middle Tennessee in January

Winter storm Fern caused catastrophic damage to our tree canopy.  Metro Parks estimated they lost more than 6000 trees throughout the entire park system. I can't even imagine how many trees have been lost across Nashville neighborhoods. Driving through my neighborhood and beyond I see very few yards that aren't affected by tree loss or damage. 

 

Tree debris is still piled everywhere. It's devastating to see the tattered and thinned tree canopy.

If I had the back and a truck I would grab so much of this wood

 

 

I've been especially concerned about how the loss of trees will impact bird populations.

Loss of the tree canopy means:

• Habitat disruption: birds have no familiar places to nest or roost
• Food scarcity: Trees provide important bird foods-sap, nuts, dormant insects
• Humans must provide more nutrient rich foods
• Nesting challenges: Loss of traditional nesting sites for returning migratory birds means a huge impact on migratory birds. Think about what awaits Purple Martins since many of their preferred trees were lost in downtown Nashville.
• Loss of nesting and food means reduced productivity-No baby birds
• Loss of cover and safety issues -Many of the trees downed were evergreens. Fewer evergreens affects safety from predators and harsh weather. 

 

Here's some thoughts on what we can do and to prepare for ice and wind storms in the future (source) 

•  Regularly Prune: Hire an arborist for "crown thinning". That's a selective pruning method that removes 10-30% of interior branches to increase light penetration and air circulation throughout the canopy, reducing disease risk and wind resistance without changing the tree's size or shape. It strengthens branches, reduces weight, and improves tree health. It is not tree topping.

• Structural Support: If recommended use steel cables and bracing for trees with co-dominant stems (V-shaped unions).
• Young Tree Care: Structural pruning when trees are young creates to create a strong framework
• Watering: Ensure trees are watered deep into the soil before winter, as hydrated, healthy trees resist ice damage better.

And now suggestions for the challenge!

If a tree needs to be cut down leave a snag

 Use fallen limbs to line your garden beds

 

Allow a fallen tree to remain in the garden. Limbs on the ground are a perfect shelter for small animals such as rabbits, chipmunks and squirrels and a habitat for beetles, termites and other insects.

 Twigs and branches play a crucial role in promoting healthy soil: adding essential organic matter to your garden soil, improving soil structure, enhancing water retention, and providing nutrients as it breaks down over time.

Use smaller twigs and branches as filler in the bottom of large containers. They act as a sustainable filler that improves drainage, boosts aeration, and reduces the weight of the pot. It's my mini-version of Hügelkultur, turning yard waste into a nutrient-rich foundation for my plants.

Make a brush pile. Stack fallen brush, tree limbs, broken pots for ground beetles. Ground beetles are excellent at eating "bad bugs". Bugs are also good bird, toad and small critter food.

 
Use a tree stump as support for a larger container.

Use pieces of downed branches and trunks as benches in your garden or to make trellises and arches.

Be creative and have fun...We found what arborists call cookies (above) and we plan to dry them add legs to make tables. And look at the critter we found (below) last year that makes us smile every time we pass by it.

Have some fun, feed your creativity, help nature and feel free to add more suggestions and to share your ideas with everyone! xoxogail

 

Here's a recap of what the First Wednesday Monthly Challenge is all about.

 

Want to Take the Taking Care of Wildlife In Our Gardens Challenge?

The first part of this challenge is to do something, even lots of things each month that support the critters living in our gardens. Gardening with native wildflowers, shrubs and trees that make sense for our ecoregion is a good place to start or continue (as the case may be). Plants and their pollinators are a classic example of mutualism: they have coevolved through evolutionary time in a reciprocal beneficial relationship. This is also true for other critters that visit and live in our gardens. 

Activities that increase our knowledge of the natural world are equally as valuable. Helping others learn about nature is included. Golly gee whiz, there are so many things you can do. 

The second part of the challenge is to post about it somewhere: Your blog, Instagram, Facebook, Twitter or even your neighborhood listserve. Wouldn't an article in the local paper be a coup for nature! Why post it? Because positive publicity is needed to educate our friends, neighbors and communities about how important even the smallest changes we make as gardeners can be for pollinators, birds, insects and mammals, including humans, that live all around us. 

Why now? My neighborhood is changing. Yours might be, too. Every day an older home along with many (if not all) of the mature oak, hickory, maple, Eastern cedar and hackberry trees are cut down. Insects, birds, even mammals lose their home site and food supplies when we lose trees. During construction soil is compacted by bulldozers, trucks and piles of debris cause runoff; surface runoff that can carry pollution to streams and rivers. It's important that our neighbors and our community have information about how important trees are to our ecosystem. Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife.

In place of the "bee lawns" composed of Claytonia, Salvia lyrata, Ruellia humilis, fleabane, Western Daisy, Violets, self-heal, clovers, native grasses (in my neighborhood it's poverty oat grass) and sedges, they're being sodded with non-native grasses. These monoculture turf lawns contribute nothing environmentally. Here's what we lose when our diverse lawns are replaced with pristine turf grass:

• Gone are the lightening bugs.
• Gone are the ground dwelling/nesting native bees.
• Gone is the habitat for insects, spiders and other critters. 
• Gone is plant diversity. 
• Gone are trees that provided for hundreds of moths, butterflies and other insects.
• Gone are the nesting sites for woodpeckers, hummingbirds, Chickadees and other birds. 
• Gone is a healthy foodweb.
  

 It breaks my heart. 

We can't stop the progmess, but, maybe we can make a lot of educational noise and help our new neighbors see the value in providing for critters and ultimately helping the environment.

A gardener can hope!

Wildflower Wednesday: Chasmanthium latifolium, A Year Round Beauty

I love native grasses and there aren't nearly enough in my garden. Shallow soil and shady conditions limit them at Clay and Limestone, but, Chasmanthium latifolium (River Oats) is deliriously happy here and it makes a gorgeous big impression....And I do mean a big impression.

I think it's important to tell the truth about plants I showcase and the truth is that while I love River Oats I need to issue a word of caution--This grass spreads through rhizomes and can be aggressive. It will also reseed itself. In fact it has seeded itself vigorously around my sunnier border and taken over spots once inhabited by other sweet native wildflowers! I don't blame the plant, that's its nature. I hold myself completely responsible that it has run roughshod over other plants.  

The first few years in the garden

When I was young and eager to have a wildlife friendly garden I chose River Oats because it had year round beauty and good wildlife value. It was easy to grow and tolerant of many different light and soil conditions. I loved that it was a larval host plant for butterflies as well as a food source for small mammals and birds. Later on I learned that it provided shelter for small mammals and was an important plant for lightening bugs.*

It was in the ground and well established when a gardening friend visited and said this to me when she noticed the large clump of river oats: "Oh my, why did you plant that?"  She knew what many of us learn from experience, that river oats can be a bit thuggish in some gardens. That's what I found out...Each and everyone of those spikelets can make a new plant in moist soil. It can in dry soil, too!  

But let's talk about its wonderful characteristics!  

River oats is a cool season clumping grass that emerges in spring before most native grasses. The bright green arching bamboo like foliage is so welcome after a brown winter.

It's especially lovely in early spring as it mingles with early spring wildflowers.

 The flat nodding green seed heads that resemble oats emerge with the foliage. The spike like flower heads sway gently in the slightest breeze making quite a statement in a spring garden.

It always strikes me as too soon when the flowers ripen into seeds, but that's to be expected with cool season grasses. Most cool season grasses are bunch grasses that grow actively in cool weather and set seed by early summer. 

And just look how lovely the yellow gold seedheads look with Physostegia virginiana. How ironic or maybe appropriate that two of the most disobedient plants in my garden dance so well together!

 

Here are two of my favorite fall photos from the archives.

It seeded itself among the witch hazels, Hydrangea arborescens and a long gone Japanese Maple tree. Below it's mixing well with a fall blooming aster.

 Full on winter finds them still beautiful.

Yellowing up on its way to bronze winter color

Since I garden for wildlife, I don't clean up my garden in winter. This means that I let the River oats and the stems of wildflowers stand all winter. This allows insects that over winter in wildflower stems a safe haven and food for birds who forage the seed heads. River oats foliage insulates and protects the plant, adds winter interest and its thick, clumping habit offers essential cover and nesting materials for birds and small mammals.

 If you're really lucky you get to see them in the snow.

 Chasmanthium latifolium has more pluses than minuses, but, plant it only if you don't mind a plant that vigorously reseeds or if you have a space in your garden where it can make its big statement! Long time readers know I am a huge fan of colonizing, rough and tumble, take care of themselves native plants and this is definitely one of them.

 I've seen it growing in rich woodlands adjacent to cedar glades where it it co-mingles with Hypericum frondosum, Rhus aromatica and sedges.  It can also be found naturally growing in rich woodlands and  stream beds slopes. It's perfect for stabilizing a stream bank or a slope that's eroding. If you've ever tried struggled to dig a clump to divide or transplant you know that its fibrous and deep root system would hold back the steepest slope!

I will be doing some editing this spring and summer! Wish me luck!xoxogail

These ornamental grasses offer protective cover for larvae and resting spots for adult fireflies, particularly in shady or riparian areas.

 

 

 Welcome to Clay and Limestone's Wildflower Wednesday celebration. On the fourth Wednesday of each month I share information about wildflowers and other native plants. Please join in if you like. You can write a blog post or share your favorite wildflower on social media. Remember, it doesn't matter if they are in bloom or not, and, it doesn't matter if we all share the same plants. It's all about celebrating wildflowers.
