How to care for wallflowers

Wallflowers (Erysimum linifolium) are easy to care for. You can plant them virtually anywhere and all but forget them. Once they come up, they'll bloom in yellow, red, orange and purple. In fact, they'll bloom until they exhaust themselves. Wallflowers are perennials in the wild, but in the home garden, the flowers often last only for a season or two before they need to be replanted.

Water the wallflowers with 2.5 cm (1 inch) of water weekly if there's no rain. To estimate how much water that is, place a rain gauge (or graduated cylinder) in the wallflower bed when you water. Always use a gentle spray of water focused on the base, not the top of the plants.

Pinch back the tips of long and lanky wallflower stalks to 6.5 mm (1/4 inch) above the nearest leaf node in early spring just before new growth begins. This will encourage the plant to branch and produce fuller growth and more flowers. To fill out thin plants, pinch the growing tips of all the stems back to 6.5 mm (1/4 inch) above the nearest leaf node.

Mulch the wallflower bed with 7.5 cm (3 inches) of organic mulch in winter once the temperatures drop. Wallflowers can survive temperatures down to -23 degrees C (-10F).
