Aubrieta Deltoidea ‘Cascade Mixed’ – (Rock Cress)
Rock Cress are extremely popular rock garden plants, and a remarkable sight in the spring garden.
This is a popular spring flowering perennial. It forms a low carpet of evergreen leaves, which cascades over walls and hillsides. The flowers absolutely cover the plant during the flowering season, making one of the most spectacular sights to be seen. The mix will you give colours of blue purple and carmine red flowers with small yellow eyes. They prefer cooler temperatures in fertile well drained soils with plenty of compost and are frost hardy. They are happiest in full sun, but can take some shade throughout the day especially in warmer geographical conditions.
Nice along pathway edges, rock walls, or in alpine containers. Plants should be trimmed lightly immediately after blooming, to encourage a thick mounding habit.
They can be propagated by cuttings or by dividing the roots every 2 to 3 years.
They are best sown directly in winter and spring. Sow into prepared soil which is fine grained. The ideal temperature for propagation is 18-20°C. Thin seedlings to 5cm spacing. They can be sown indoors, surface sow onto moist, well-drained seed compost. Just cover seed with vermiculite. Propagate 18-21°C. Germination takes 14-21 days approx. When seedlings appear ensure they are not covered and have plenty of air movement so that they don’t dampen off. Transplant seedlings when large enough to handle to 8cm pots and grow on. Acclimatise and plant out once danger of frost has passed. Autumn sowing will flower the next year.
