Great Design Plant: Golden Alexanders for Early Spring Color

I'm a big fan of native plants and having my garden in bloom every day of the year. Early spring to midspring often presents a challenge, but Golden Alexanders (Zizia aurea) rise to the occasion. This prairie and meadow standby is tough as nails, and since it's in the carrot family, it also serves as a butterfly host plant. Let's explore why this might be the perfect plant for your early-season garden.

Distinguishing Traits

Golden Alexanders is low-maintenance and adaptable, preferring full sun but tolerating some shade. It hosts several swallowtail butterfly species, including black swallowtail and Missouri woodland swallowtail.

How to Use It

Plant en masse in groups of three to five or more for impact, as individual flowers are small though profuse. It's ideal for the middle or front of the border, shining in spring when little else blooms. It also offers attractive fall foliage in plum-rust-red tones and will self-sow lightly in open ground.

Planting Notes

Moist to medium soil is best, but it shows remarkable drought tolerance, making it great for rain gardens. Sow seeds in fall or winter for a spring show. Watch for small spherical eggs on leaves—a sign of visiting swallowtails.

The similar Zizia aptera is more drought-tolerant with heart-shaped leaves, native in scattered locations from the Northwest and northern Rockies into the Midwest and Appalachia.
