Alyssum serpyllifolium-Alpine Alyssum or Madwort

Couldn’t find much on Alpine Alyssum for propagating but since it grows in a mound shape and will self seed if the soil is well drained, I believe digging it up in the fall and splitting the crown with a sharpe knife and then transplanting you should be safe. Also you can collect the seeds after the seed heads dry. It has thyme like leaves, silver, and it blooms are yellow, flowering in May/June and prefers a gravely soil that is well drained. It reaches a height of 2"-4", is said to be deer resistant, prefers full sun, is drought resistant when established, is evergreen and is native of the Iberian peninsula.
