For zones 3-10 White Rockcress is a dry climate perennial flower that will grow in most zones as long as you sow, or plant it, in an area of your garden that get's good drainage. They will not do well in soggy areas and prefer a sandy or rocky garden area.

These seeds are very tiny so if direct sowing it's best to use the shaker method and mix your seeds with sand to spread, or mix your packet with 4 cups of peat and spread in your garden area.

In very early spring enrich your garden soil 6" deep and distribute your seeds and top with a very light dusting of peat as Rockcress needs light to germinate. Keep moist until germination. Rockcress will not germinate in dry soil.

You can also start Rockcress in pots 8 weeks before your last frost in the spring and transplant into your garden after your last frost. As above spread on the surface of your potting material and lightly dust with sand or vermiculite. Keep your pot/tray (with holes in the bottom) in a tray containing about 1" of water and cover lightly with plastic wrap. Keep your pot/tray under lights until germination and once your seedlings are 2" tall you can transplant them into your garden in spring after your last frost.
