Name: Riddell's Goldenrod
Type: Oligoneuron riddellii
Description:
Riddell’s Goldenrod produces mounded clusters of lemon-yellow flowers from August through October. As the plant blossoms, the leaves will often wither away, drawing attention to the bobbing yellow buds atop naked stems; these turn a ruddy red as the coolness of autumn creeps in and transforms the flowers into tufted, oatmeal-colored seedheads. This goldenrod prefers full sun, wet to moist conditions, and calcareous soil containing some sand or gravel. New plants can be started from seeds or by division of rhizomes. Highly attractive: bees including yellow-faced bees, Andrenid bees, sweat bees, small and large carpenter bees, digger bees, and bumble bees; also highly attractive to honey bees.
