Where to Plant: Use it at the front or middle of a sunny border, or in a big pot on the patio where you can watch the colours shift. It's rated to zone 7 and our winters are colder, so treat it as a long-blooming annual or a container plant.
Companion Plants: Verbena stricta adds slender lavender spikes at 60 to 100 cm from June to September. Eryngium 'Blue Glitter' brings blue sea holly at 90 cm from June to August. Cerastium 'Silver Carpet' edges the bed with white flowers in May and June. Orange rudbeckia from June to October glows against the cool blues.
Plant Care: Plant it in full sun in average, well-drained soil. Water regularly while it settles in, and keep an eye on containers in hot weather, since pots dry out much faster than garden beds. Snip off faded flowers to keep the plant tidy and the new buds coming. No staking is needed on its sturdy stems. After a hard frost ends the show in late fall, pull the plant and add it to the compost. If you want to try overwintering one, a very sheltered, well-drained spot is your best bet, but don't count on it.
History: Black-eyed Susan, Rudbeckia hirta, is a wildflower native to eastern and central North America and has been Maryland's state flower since 1918. Solar Sisters™ was introduced through the Bloomin' Easy® program and won both the Industry's Choice and People's Choice awards at the 2025 University of Georgia Trial Garden open house.
Final Thoughts: Compact, sturdy and a pollinator magnet. Plant two and let them fight over the spotlight. SIBLING RIVALRY HAS NEVER LOOKED BETTER.
