Erysimum kotschyanum Erysimum kotschyanum Erysimum kotschyanum Dwarf mounds, bright yellow flowers in spring. £2.60 Quantity: at £2.60 each Add To Basket A very nice dwarf, forming neat, low mounds of dark green topped with many small yellow flowers in spring. Enjoys a sunny site and prefers a poor, gritty soil. This is a gem and one would never guess that it's actually a Wallflower, although the little flowers are just as fragrant as their bedding plant cousins. And this lives for years. Suitable for a stone trough. Barely 3 cm high with slightly taller flower spikes.
