Gardeners will find that a number of new sedums will be available in 2010. The following new varieties are recommended.
Bon Bon sedum telephium is a hardy perennial. This is recommended for zones three through nine. It needs full sun to partial shade.
Reaching nearly 1½ feet in height, Bon Bon has delightful deep blackish to brown foliage. The pink blossoms open very early, and appear in large flower heads. The contrast of the pink blossoms against the dark foliage is particularly striking. The dense, much branched plant has a round, neat growth habit.
Sedum Black Beauty is a new hybrid. This well rounded, much branched perennial is compact. It is named for the very dark foliage, which is deep bronze to black. It is medium in height. The large pink blooms open in very large flower heads. Black Beauty is hardy to zone three or so.
Sedum Plum Perfection is hardy to zone four. A dwarf plant, this is only about six inches in height and nearly a foot across. The foliage is greenish-gray with tinges of plum. This has a mounding growth habit. Starting in the late summer and fall, the pink blossoms begin to appear. This grows well in both full sun and partial shade.
Sedum Thundercloud is about the neatest looking stonecrop one can imagine. The plant is perfectly rounded, and forms a very tidy clump. Thundercloud is about a foot in height with a matching spread. The very pointed leaves are greenish-gray. This is hardy to zone three, and prefers full sun. This is a late blooming variety. The white blossoms begin to emerge in early September.
Sedum T. Rex autumn stonecrop is a wonderful new introduction that will become a classic. Hardy to zone three, this wonderful perennial maintains its upright growth habit even when the heavy flower heads begin to open. This is a very tidy looking plant that reaches over two feet in height. It can be nearly three feet across.
The attractive green foliage has notched edges. T. Rex begins blooming during late summer. When the flower heads first begin to open, the blooms are cream to pale pink. Over time, these deepen to a reddish-pink. This carefree plant is resistant to disease.
