For zones 3-10 Purple 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.
Rockcress is an heirloom variety of Aubrieta, and even though there are numerous mis-leading pictures of this flower online, it will only spread to 6". Sellers often post pictures of the much more expensive Aubrieta Cascade which is a hybrid of this flower and will trail between 12"-18".
We find it's best to start these early in pots by sowing your seeds on the surface of your potting mix and lightly dusting with fine sand or vermiculite. Expose to light and keep cool as they will not germinate in hot temps. We keep our potting mix moist 24/7 until germination occurs.
If direct sowing sow in early spring in your garden as described above, but dust with a very light topping of screened peat to protect the seeds from birds until they germinate. When using either method keep moist until germination. Rockcress will not germinate in dry soil or high summer heat.
