Positive Todd_Boland On Dec 9, 2004, Todd_Boland from St. John's, NL (Zone 5b) wrote:

A wonderful Alyssum for the rock garden. Plants literally smother themselves in bright yellow flowers throughout most of the spring and into early summer; there are even scattered flowers throughout summer. Plants form a sprawling mat of small grey-green leaves and terminal clusters of flowers. Easy from seed or from herbaceous cuttings taken in early summer. It is native to grassland slopes of East and Middle Asia as well as Siberia.
