Cascade Blue
Rock Cress
Cascade Blue rock cress is a spreading, evergreen perennial. Plants form carpets of brilliant, deep blue spring flowers. Cascade Blue rock cress is a superb ground cover for dry banks, underplanting shrubs, or in rock gardens, between flagstones, or along pathways. Plants grow 3-6 in. high, and spread 1-1.5 ft. across. Winter hardy to zone 4.
Growing Cascade Blue Rock Cress Seeds
Plant Rock Cress Seeds: Sow rock cress seed in cell packs or flats, use a sterilized mix, press into soil, do not cover. Needs light to germinate. Kept at 70°F., germination is in 14-21 days. When large enough to handle, transplant seedlings into 3 in. pots. Once rooted, place into the garden 12 in. apart.
Grow Rock Cress: Prefers part shade in hot climates, full sun where summers are relatively cool. Plants prefer lean soil, need well-drained soil. Cut back halfway after bloom. Flowers attract bees.
