Wildflower Wednesday: Alabama Croton Revisited


I can clearly recall the first time I saw many of the Wildflower Wednesday stars, but, Croton alabamensis is not one of them. What I remember was how long and hard I searched for it. I was thrilled when Paul Moore, a dear friend and fellow wildflower aficionado offered a seedling to me. I clearly remember the day I drove to his garden to pick up the Alabama croton. If one can dance while driving it was certainly me.


Let me say first that Paul's garden is lovely. It sits on the top of a hill in southwest Davidson county over looking Nashville. It is a beautiful and artistically designed garden and reflects  Paul's sensibilities as a landscape photographer and a native plant lover. The wildflowers are scrumptious, as is his moss lawn! But, I digress...and will show you his garden another time.

Alabama Croton has formed a thicket in Paul's garden (1/20/14)

You get your first look at Alabama croton as you drive up the long, curving drive. There was a large planting, at least 20 feet wide and 6 feet or more deep.

February 25, 2020

It was a gorgeous thicket of silver and orange fluttering leaves; striking against the winter blue sky. It is clearly a year round beauty and I was so fortunate to be taking home a seedling for Clay and Limestone.

I wanted that thicket in my garden and planted the seedlings right were I thought they would be happiest; on a sunny slope, where it would get sun and the drainage it would need in our wet winters.

Alas, my dream did not come true, several years later the city tree trimmers dropped limbs from my poor desecrated Bur oak on top of the bed it was planted in. To add insult and further injury, the workers stomped all over the plants while picking up the limbs. I was pretty steamed and terribly sad when I came home to find it and several other plants destroyed.
There are three seedlings in the container (2/25/20)

Fast forward to now, Paul, generous friend that he is, is digging seedlings for me. When he messaged me that he had plants for me, I rushed over to get them. In case you wondered, there was happy dancing going on.

Alabama croton is endemic to a few counties in Alabama, one county in Middle Tennessee (Coffee) and three counties in faraway Texas (Croton alabamensis var. texensis/Texabama croton) and is still nearly impossible to find for sale.

Alabama Croton is the bees knees.

  • it's not deterred by dry, poor, limey soil
  • it easily braves hot summers like we've been having the past few years,
  • it will grow in decent garden soil that is well draining,
  • it grows in the full sun, but, can appreciate a semi-shady location, 
  • it's native to Middle Tennessee, 
  • it's locally sourced, and 
  • it has year round interest.
This rare, semi-evergreen southern shrub is worthy of wider use in gardens. Alabama croton is an irregular, multi-stemmed shrub that grows to 5′ tall. Its bright green foliage with striking, silvery scales beneath is attractive in summer as well as in autumn when it develops pumpkin-orange colored foliage.
Can you see the silver scales on the leaves?

It produces very few leaves, but, the ones it has are noted for their elliptic to oblong-shape and glistening silver scales and stunning autumn color. In milder winters the leaves hang on and flutter green and orange until spring.


That's exactly what you see when you visit Paul's garden.

Croton alabamensis performs well in full sun to partial shade in well-drained to very dry soils. It is tolerant of slightly acidic to very alkaline soils. I've found that it needs very good drainage and that was one reason it was planted on the sloped section of the garden under the over hanging limbs of the Bur oak.

Alabama croton is a good companion when planted with Rhus aromatica, Clematis viorna, Coreopsis auriculata, Phlox divaricata, Schizachyrium scoparium, Amsonia ciliata var. tenuifolia, Coreopsis grandiflora, and Liatris microcephala.

Those companion plantings sound delightful and I have some seedlings of Amsonia, Coreopsis and Liatris to plant with it. I do hope it forms a thicket.

Mature shrubs produce 2" panicles of pale yellow blooms in the late winter or early spring. They're   highly attractive to bees and butterflies. In fact, it's a host plant for the Goatweed Leafwing butterfly.

Welcome to Clay and Limestone and Wildflower Wednesday.  Thank you all for joining me as we celebrate and share our marvelous and beautiful wildflowers. I hope 2020 is the year we all plant more native wildflowers for the many critters that live in and visit our gardens. Let's be sure we celebrate them every day, not just WW. Remember, it doesn't matter if they are in bloom or not, you can still share them. Please leave a comment and add your name to Mr Linky so others can pop over to see your Wildflower Wednesday post.

Wildflower Wednesday: Golden Alexander


Our Wildflower Wednesday star of the month is Golden Alexander. It's a lovely wildflower and should have been a Wildflower Wednesday star years ago, but, it has always been over shadowed by the showier early blooming Aquilegias, Baptisias and Phloxes.

That is until this year, when I noticed how nicely it had seeded around the garden.
I don't understand why they are so rarely planted. It's a stellar plant for early season color and the small flowers are an important and easily accessible food for tiny pollinators. There's a lot of other flowers in bloom when the Zizia flower in my garden, but, colder climate gardeners, I think this is a must have plant for your wildflower garden!
tucked in between an ex-aster and goldenrods
I thought them sweet when I planted them half a dozen years ago, and, have come to value their lovely yellow presence and their pollinator magnetism. They look beautiful when massed and viewed from across a garden, but, I like them best up close, where I can see the pollinator action.
Blooming begins in late spring and continues for about a month. 
If you like critter action in your garden, you'll find it on Zizia. They're very attractive to butterflies and to short-tongued insects. I see little carpenter bees, tiny beetles and other  fast flying critters when the sun finally makes its way over the trees and the garden warms up. They never hold still for photos, so you'll have to trust me and go ahead and plant this wildlife valuable beauty in your garden.
Deep green, leathery, handsomely foliage
Zizias are members of the carrot or Apiaceae family. They have rounded or flat topped compound umbels (think umbrella and you'll never forget) of tiny yellow florets that produce both nectar and pollen. Each umbel averages 2-3” across and can contain as many as 250 florets that are about 1/8” wide (from Illinois Wildflowers).
That is a lot of goodness in those tiny flowers and their nectar is easily accessible to short tongued bees and other critters
That's a powerfully attractive flower head for pollinating critters.

 Like other members of the carrot family (fennel, dill, parsley, cilantro, lovage and chervil), Zizia is a food source/host plant for the Black Swallowtail butterfly and its caterpillar, but many other small pollinators and beneficial insects are attracted to the flowers.

 Zizia aurea is a classic carrot family member and knowing its characteristics would make identifying it and other Apiaceae easy peasy in a woodland. Look for clustered small white or yellow flowers that make you think of an umbrella spokes! The clusters are called umbels and are actually individual flowers on stalks arranged like the spokes of an umbrella. You can practice in a herb/vegetable garden where you likely to find many carrot family member.

Golden Alexanders bloom in April in my Zone7, Middle Tennessee garden. Native to Tennessee and Davidson county where I live, they are usually found in wooded bottomlands, stream banks, moist meadows, and floodplains. They're native from Canada to Florida and east of the Rockies. They're a good choice for heavy clay soils in semi-shade to full sun. They're happy in moist soil but, once established they have some drought tolerance. They've been happy at Clay and Limestone and I never worry that our wet winters will kill them.

If you garden for pollinators, especially butterfly, you won't be disappointed with Golden Alexander. So give it a try. If it's happy you can enjoy a massed golden show.

Genus: Zizia
Species: aurea
Common Name: Golden Alexander
Family: Apiaceae
Flowering: flowers in April-May in my middle Tennessee Zone 7 garden
Native Range: Eastern Canada to southern United States
Zone: 3 to 8
Size:  Height: 1.50 to 3.00 feet Spread: 1.50 to 2.00 feet
Bloom: yellow, umbel
Sun: Full sun to part shade
Water: Medium
Soil: Heavy clay,
Maintenance: Water in droughty times if newly established. Unwanted seedlings might be an issue
Foliage: Attractive
Pollinators: Zizia is a food source for short-tongued insects that are able to easily reach the nectar in the small yellow flowers. Black Swallowtail butterflies feed on the nectar and lay eggs on the foliage and when the eggs hatch the caterpillars will feed on its leaves.
Propagation: Plant in the spring for good success. It spreads by seeds.
Wildlife: Has never been predated by deer or voles.
Comments: A delightful plant to allow to seed itself about in a damp sunny meadow. Use in a rain garden or in natural garden. Plant with Carex, Aquilegias, Packera aurea and other plants that like moist soil. Golden Alexander also attracts and hosts a number of beneficial insects that are predatory or parasitoid on many common garden pest insects.(Illinois Wildflowers)

Welcome to Wildflower Wednesday and thank you for stopping by to see my Golden Alexanders! Thanks for joining in and if you are new to Wildflower Wednesday, it's about sharing and celebrating wildflowers from all over this great big, beautiful world. Join us on the fourth Wednesday of each month. Remember, it doesn't matter if your wildflower is in bloom or not and, it doesn't matter if we all share the same plants. Please leave a comment when you add your url to Mr Linky.
