Black-Eyed Susan Growing Basics

 

Black-Eyed Susans may be among the most common plants, but they also exude a sunny disposition with their bright yellow and gold petals

As wildflowers, go, Black-Eyed Susans are pretty common. Unless you wish to consider the sunny yellow florets that surround a conical brown button. When grouped in bunches, they're simply spectacular and should bring a smile to anyone's face. This is probably what made them the state flower of Maryland!

Its botanically known as Rudbeckia, with around 25 species (4 that are specifically "Black-Eyed Susan") that include R. fulgida (Goldsturm) and R. hirta. In common terms may be called yellow oxeye daisy and gloriosa. Black-Eyed Susans are members of the aster family and related to daisies. There are cultivar names as well: Bambi, Supurba, Irish Eyes, Toto, and Double Gloriosa.

The Black-Eyed Susan grows hardily in Zones 3-10, as an annual, perennial, or as a biennual. It loves a well-draining, moist soil and absolutely adores the sun. On the other hand, it is an extremely tolerant plant if neglect comes its way. It's also, by the way, considered an invasive weed.

Seeds can be planted just by placing in soil a week or two before the final frost of the season. They need sunlight to germinate. They should remain moist until established. They'll sprout quickly and provide blooms from as early as April through the late fall.

Black-Eyed Susan makes a stunning cut flower for arrangements as well. It will stay in healthy bloom for up to ten days. Because it's so prolific, there will be plenty to display indoors through the blooming season. Deadhead the spent flower to encourage faster growth.

The Black-Eyed Susan vine is actually known as Thumbergia Alata. But its popularity commonly lends itself to a comparison. Some of these can trail as high as 12 feet while other make terrific groundcover or are grown in containers. They are considered annuals in Zones 2-11, but will come back on Zones 10 and 11.

Look for such varieties as Susie (the most popular), Angel Wings, Lemon Star, and Sunny Orange Wonder.
