Aurinia saxatilis. Basket of Gold Alyssum seeds produce a low-growing evergreen perennial with a profuse golden bloom from mid- to late spring. It is widely used in rock gardens and alpine beds, or cascading down rock walls. Butterflies, bees, and birds are attracted to the dainty flower clusters. After bloom, its attractive silvery foliage makes a wonderful ground cover. Provide good drainage in full sun. Named for its similarity to Alyssum, Basket of Gold is not a true Alyssum. Rather, it is a fairly tough and easy perennial plant that blooms from mid-spring to the beginning of summer. Height to 8-30cm (4-12"). Hardy to Zone 4.
This evergreen perennial bears the slightly misleading common name Basket of Gold Alyssum. Remember that the common name Alyssum is a bit misleading. This Basket of Gold Alyssum is actually Aurinia saxatilis, and Snow Cloth Alyssum is actually Lobularia maritima. Alyssum describes the shape and size of the plants more than any true botanical details. Continue reading below for some tips on how to grow Aurinia from seed.
Exposure: Full sun
Zone: Hardy to Zone 4
Indoors, start Aurinia seeds 8-10 weeks before planting out. Or direct sow in early spring, when there is still a risk of frost, or in early autumn.
Sow seeds on the surface of the soil. Light is required to help the seeds break their dormancy. At 10-12°C (50-55°F) Aurinia seeds will take 5 to 14 days to sprout.
If transplanting from indoor starts, do so in early spring when the soil is still cool, but the threat of frost has passed. Daytime temperatures should be steadily above 10°C (50°F). Space plants around 30cm (12″) apart in full sun, in well-drained soil. Aurinia plants will become leggy in rich soil, so do not feed. Water plants in periods of very dry weather. Cut plants back hard after flowering to prevent self sowing.
