Blue-stemmed Goldenrod
The blue-stemmed goldenrod is sometimes referred to as Wreath Goldenrod. It is a well-behaved woodland species. It forms pretty, loose clumps with arching stems and long, thin leaves. Tiny clusters of bright yellow flowers form in the leaf axils for half the stem’s length. Stem color in mature plants has a dark, bluish tone.

The blue-stemmed goldenrod is usually found in upland woods where deciduous trees dominate. It bears bright yellow fowers in the fall, which are on long, slender stems that turn bluish or purplish with age. It is a perennial that grows 1-3 feet and tolerates shade and various soils.

Planting

Open deciduous woods
Water requirement: Adaptable moisture
Well drained soil

Care

Plants are tough. Easily grown in average, dry to medium, well-drained soils in full sun to part shade, and does not spread aggressively as do some of the other goldenrod species and hybrids.
It may be affected by powdery mildew, rust or fungal spots.

Pruning

Spread: Up to 50cm
Deadhead to prevent self-seeding. Divide in spring or fall.

Considerations

The blue-stemmed goldenrod attracts many pollinators such as bees and butterflies. White-tailed deer may browse the foliage, but they are generally unpalatable to deer or rabbits.
Native to Canada

Styling and Use

Liked for native plant gardens, open woodland gardens, borders, wild gardens, cottage gardens, meadows or butterfly gardens.
Try pairing Solidago caesia with Aster cordifolius, Chasmanthium latifolium, Chrysogonum virginianum, Heliopsis helianthoides or Amsonia hubrichtii.

Other

It is commonly mistaken for a plant that causes hayfever, but this is not the case. Hayfever is caused by wind-borne pollen, but the pollen from the blue-stemmed goldenrod is actually transported from bloom to bloom by bees, butterflies and other pollinators.
