In German, "matrone" means a lady of well rounded form"...alluding to the robust nature of the sedum. Plant Delights
A favorite perennial should be as handsome in leaf as it is in bloom. In that category, I nominate Sedum 'Matrona'. Superior to 'Autumn Joy' in every way, 'Matrona's' blue-gray leaves are thicker and more succulent, almost cactus-like in their appeal. Though plants reach just 24 inches high, they look larger when massed. Perhaps it's the visual weight of their remarkable foliage. HGTV
Sedum spectabile is an old-fashioned perennial with cabbage-like rosettes of succulent foliage throughout summer. Towards mid-summer, flat tightly-packed heads of green buds appear just above the foliage; these form a feature in their own right, and floral artists often cut them at this stage. In late summer the buds gradually open to reveal masses of tiny flowers, in this variety bright rose-magenta. They are highly attractive to butterflies, and several species can be found crowding over the flowers, making an additional attraction in the autumn garden. This is sometimes listed as Hylotephium spectabile. The Royal Horticultural Society have given it their prestigious Award of Garden Merit (AGM). Gardener's World
