Erysimum ‘Gold Rush’
Erysimum ‘Gold Rush’, also known as Wallflower, is a lovely plant that blooms from mid spring to summer, producing lots of rich yellow flowers.
It grows about 8-12 inches tall and 12 inches wide.
Unfortunately, it is a short lived plant, so take a few seeds and sprinkle them around before cutting off the rest of the seed heads.
This will promote longevity in the plant, and simultaneously get new plants started.
It does best in full sun and well drained soil. Hardy in zones 6-11.
