One of the most attractive solidagos IMHO, with it tall, full columnar or pyramidal flower spikes. More flower to foliage ratio than most other solidago, and looks appropriate in a garden as well as large wild settings. The listings claim it grows 1-3 feet, but we've gotten some 4-5 footers even before flowering, and one major prairie native plant nursery also lists the height at 5 feet. Looks great with tall, blue native asters like sky blue aster (A. azureus/A. oolentangiense/Symphiotrichum oolentangiense) & smooth aster (A. laevis/S. laeve), which bloom during the same period.

Drought tolerant, and attracts pollinators (bees, beetles, & some butterflies & moths) in droves. Seeds are sometimes eaten by American goldfinches & greater prairie chickens, although it's not ... read more

This plant has thrived under fairly challenging circumstances. I planted it in the most impoverished clay soil, though certainly well drained. Further, I permitted a bean plant to vine over it. (I get a kick out of permitting beans and tomatoes to act as weeds in my otherwise native American yard, because it makes my whining about the weeds more amusing.) I think I would advise against putting it in soil that it would like, but it's quite quite delightful in well drained clay which puts a damper on the goldenrod tendency to spread.

I have not grown this plant. Showy goldenrod is a deer resistant, native rhizomatous plant that inhabits almost all of North America. Preferring sandy to loamy soil, it can grow in poor dry soils as well as medium wet soils as long as the soil is well drained. It can be found in fields, open woods, meadows, prairies, along roadsides and in thickets reaching a height of between 2 and 3 feet and between 2 and 3 feet wide. Thriving best in full sun, it can tolerate very light shade.

The lance-shaped, toothed, hairy leaves densely alternate along upright reddish colored stalks from ground level to club-shaped, terminal, clustered flower heads which occur from late July through October. The thick, branching heads have tiny bright yellow flowers. To prolong blooming, remove the s... read more
