Rudbeckia laciniata, commonly referred to as Cutleaf Coneflower (not to be confused with Echinacea) is hardy to USDA zone 3. It is covered with golden-yellow flowers typical of a Black-eyed Susan in late summer to early fall. It prefers a sunny and well-drained location in the garden. Can you imagine a huge patch of this surrounded by mounds of ornamental grasses? This plant can absolutely revitalize your garden in late summer when everything else is looking a little crispy and faded. Think big scale with this one. It isn’t a plant for the small container garden.
August-Blooming Rudbeckia Brings Late Summer Gardens to Life
August 15, 2011 by jeffreyerb
As I was doing a late season nursery trip last week I came across Rudbeckia laciniata ‘Una Belle’ which took me by complete surprise. The sheer height and scale of this perennial make it stand out. We tend to use Rudbeckia as a low maintenance fail-proof perennial that gives a golden punch of color in mid to late summer, but this cultivar of the Asteraceae family adds height to the garden as it grows up to 6′ tall.
