Erysimum cheiri, syn. Cheiranthus cheiri, the wallflower, is a species of flowering plant in the family Brassicaceae (Cruciferae), native to Greece, but widespread as an introduced species elsewhere. It is also treated as a hybrid under the name Erysimum × cheiri. It is widely cultivated as a garden plant.
How to keep Erysimum Ux Cheiri.
Water
Wallflowers are drought-tolerant plants that do not need a lot of water. Water wallflowers often as they grow, and then trim them back after they have grown. If necessary, augment sporadic rain with spot watering. But keep in mind that wallflowers can not accept wet feet or roots sitting in standing water, so avoid planting them in very moist areas of your yard.
Temperature
Warm temperatures are required for wallflowers to grow evergreen. They are hardy in U.S. zones 6-9 but may even survive in colder climes. They are incredibly adaptive and may thrive in both dry and wet situations.
Fertilizer
Wallflowers don't need much fertilizer to grow. For the greatest results, incorporate compost into the soil before planting and use an all-purpose fertilizer in the early spring and mid-summer.
Pruning
Regular trimming allows wallflowers to flourish. They should be pruned down after they have finished flowering, or in the early spring. Prune them until there are just a few inches left above the earth, and they will repay you with thick new growth once conditions warm up again.
