Plants which flower early, and continue a long while in bloom, are
deservedly preferred, more especially by those who content themselves
with a partial collection; of that number is the present species of
Alyssum, which begins to flower in March, and continues to blossom
through April, May, and June, and, if favourably situated, during most
of the summer.

It is properly a rock plant, being hardy, forming with very little care
a neat tuft of flowers, and not apt to encroach on its neighbours.

May be propagated by parting its roots in Autumn, or by cuttings.

Is a native of the Levant, according to Mr. AITON; and
cultivated by Mr. MILLER, in 1739, but omitted in the 6th 4to.
edition of his Dictionary: has usually been considered by the Nurserymen
about London as the _hyperboreum_.
