Sweet Alyssum is native to the Mediterranean regions.
Alyssum maritimum now known as Lobularia maritime, grows to a height of 100-150mm (4”-6”) and spreads to around 300mm (12”)

Alyssums thrive in any ordinary, well-drained garden soil, in full sun.
Dead-heading regularly by lightly trimming the plants with scissors, will prolong the flowering season.
It re-seeds prolifically and the resulting self-sown plants can be transplanted to any desired location when large enough to handle.
Sow seeds in boxes/trays of seed compost and germinate at a temperature of 18°-20°C (64°-68°F)
Germination should take around three or four days.
Prick out the seedlings into boxes of John Innes potting compost No. 1 (or equivalent) when large enough to handle and harden them off in a cold frame before planting out.
Alternatively, sow the seed thinly in the flowering site if weather conditions allow circa Week 16.
Thin out the seedlings when large enough to handle to the required spacings.
Plant out in a sunny position 200-300mm (8"-12") apart.
