Prarie Sun Rudbeckia
January 4, 2010
Rudbeckia hirta flowers are also known as Gloriosa daisies, or Black-Eyed Susans. This specific variety, Prarie Sun, is an annual where I live, but a biennial in warmer zones. I start mine from seed, but have seen them offered as starts in nurseries in recent years. Letting them reseed in the garden is an option also, but note that if you have more than one type of Rudbeckia hirta planted, the seedlings can be a cross. Easy to grow and low maintenance, the presence of this flower in any bouquet spreads cheer and happiness.
The green center is quite different from other Rudbeckias, and lends it to be a bit more versatile for various styles of arrangements. The size of the flower varies, but are typically 4 – 6 inches across.
Height – 2 1/2 to 3 feet
Light requirements: grow in full sun
Bloom time – mid summer through fall
Hardiness – biennial in zones 5 – 8
