Many are great in troughs, crevices or small-scale rock gardens, forming nice evergreen cushions with lots of early season flowers. When grown in a container, they don't like it too wet or too dry and benefit from a little fertilizer now and then to look their best.
Spiny rosettes with racemes of yellow flowers in early spring. Sun, gritty, sharply drained soil. 6" x 6" Hardy to –20 degrees F. Rocky grasslands in the Eastern Alps, Carpathians and Balkans. Brassicaceae
This group of Draba sp was grown from a commercial seed mix. Although many look like D. aizoides, there is quite a variety. They are all small cushion forming perennials with racemes of bright yellow flowers in early spring. They are one of our earliest bloomers and make quite a show. Grow in full sun in gritty, sharply drained soil. Top dress with grit. Nice addition to troughs, alpines frames and small-scale rock gardens. Zones 4-6. Brassicaceae
