Salvia greggii ‘Ultra Violet’: Iridescent deep purple flowers from summer to fall. This accidental cross (thought to be a hummingbird initiated cross between blue-flowered Salvia lycioides and rose-pink Salvia greggii) was selected by Lauren Springer and Scott Ogden in their Ft.

Salvia greggii ‘Furman’s Red’: Dark red flowers bloom off and on all summer. Incredible plant to attract hummingbirds–and hummingbird moths! Really, all the red salvias should be planted in a hummingbird garden. Hardiness….questionable.

This great group of succulents has a lot going for it–texture, leaf color, flower color, heat and drought tolerance. The only negative that I can see is that deer like them. In general, here at the nursery, they only eat the taller varities like Sedum ‘Autumn Joy,’ and don’t bother the lower ones like ‘Angelina’ or ‘Voodoo.’

Sedum sediforme HARDY BURRO’S TAIL: This one looks much like Angelina, above, but has a grayish-bluegreen cast to the leaves. Does well in full sun to light shade. 6″ tall. Zone 5.
Sedum sieboldii OCTOBER PLANT: 10″-12″ tall; pink blooms in September. Zone 4.
Sedum spathulifolium ‘Cape Blanco’ Silver leaves are this sedum’s claim to fame. It’s one of my favorites, but a little tricky to grow. It likes rocky well-drained soil, and a bit of shade from the hot summer sun. Does well in troughs and rock gardens. Three inhes tall and 10″ wide. Zone 5.
Sedum spectabile ‘Autumn Fire’ AUTUMN JOY SEDUM: Pink flowers age to rust. Holds its color longer than Sedum ‘Autumn Joy.’ For sun to part shade. Attracts butterflies. 2′ tall. Zone 3.

Stachys byzantina ‘Silver Carpet’ LAMBS EARS: Soft fuzzy silver leaves make a great groundcover. No flowers to spoil the effect or send seeds everywhere. 12″ tall. Zone 4.
