Wildflower Wednesday: Zizia aurea

Our April Wildflower Wednesday star is Golden Alexander with its delicate clusters of bright yellow flowers. When I saw them massed in a meadow garden at the Chicago Botanical Garden a few decades ago I knew I had to try them at Clay and Limestone. I look forward to their lovely yellow presence and their pollinator magnetism in early spring. 

Blooming begins in late spring and continues for about a month. 

I planted a few and they reseeded quite nicely into a small colony. They do look beautiful when massed but, I like them best up close where I can see the pollinator action. And there's always pollinator action to observe! 

 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 about their pollinator activity! And don't be afraid of their reseeding skill. They are spectacular massed.

What can I say about their wildlife value? A lot. They provide essential nectar and pollen for short-tongued bees, wasps, and flies, and are a primary larval host for Black Swallowtail butterflies. They also attract beneficial insects that will predate on garden pests. 

   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 identifying in a herb/vegetable garden where you likely to find many carrot family member.

Why plant Golden Alexander:

•  It offers a vital food source for beneficial insects early in the season when few other flowers are available. 
• the lady beetles and parasitic wasps that it attracts helps maintain a balanced ecosystem
• deer, rabbit and vole resistant
• adapts to various soil conditions although it prefers moist soil    
• the flowers are attractive to many kinds of insects seeking pollen or nectar, especially short- tongued bees. It attract a variety of butterflies, native bees, bumble bees, and honeybees to the garden.      
• host plant for Black swallowtail butterfly      
• thrives in full sun to part shade, damp meadows but can survive dry conditions 
• it's so perfect there are no cultivars!  

 

 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. I do give them an extra drink of water during the droughty summers, especially these last few years when we've had severe droughts.

The Particulars 

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, but are easily shared and moved to other parts of your garden.

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 seedlings in the spring for good success. Seed will germinate after 90 days moist, cold stratification. Germinates at high percentages. Expect it to reseed.
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)

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.

PS Please remember to never, never, never, never, ever use pesticides in your garden. Also, be sure the plants you plant are free of neonicotinoids. Believe me when I say you want to welcome insects to your garden!
