Aubrieta ‘Whitewell Gem’ – Purple Rock Cress and 50 similar items

PLANTING INSTRUCTIONS Aim for soil chemistry between 6.0 and 7.0 pH. Again, there are conflicting recommendations, with some reputable sources calling for acidic soil, and others swearing up and down that rock cress requires a bit of alkalinity. All agree that neutral soils are just fine, and you can experiment if you want to. Moisture Requirements: Once established, let the soil dry in between irrigation periods. Plant Height: 6" to 8" tall; upright, flowering stems may reach 12". Plant Width: 2' spread. Growth Habit: Mounding, spreading, cascading; some varieties are climbers. Bloom Period: April until early June. Flowers: 1/2" wide, sweetly fragrant; typically dark purple, with other species flowering in white pink, indigo, or lilac with yellow centers. Foliage: Narrow, spoon-shaped, deep green to blue-green leaves form opposite pairs on branching stems. In some species, the leaves are lobed or flat.
