Though mostly associated with Rock Gardens, there are some excellent Sedums which deserve full marks amongst the dwarfer herbaceous plants. There are enough kinds to cover the whole season, for S. rhodiolain spring. It has a fleshy and tufty yellow above blue-grey imbricated to make a neat clump effective for a long time though only 9 inches high. S. heterodontum is a fine but little known plant of similar habit with bronzy foliage and burnt orange coloured heads in April. S. aizoon is a summer flowering yellow, and the best form is the orange coloured S. aizoon aiirantiacum, which grows to about 12 inches with a coppery tinge to the . Also in July-August there is the brilliant 9 inches S. ‘Ruby Glow’ with headed flowers above glaucous foliage. This theme is magnified when the large plate heads of pink above ‘ice plant’ foliage open in September in the S. spectabile varieties, such as S. ‘Brilliant’. These do not differ greatly in colour, and all are about 15-18 inches high, with the 9 inches diameter heads glistening and attracting bees and butterflies. The ultimate is S. ‘Autumn Joy1 for this has even larger plate heads, on almost 2 feet tall. The colour is light pink at first and by October has changed to a salmon- shade till in early November it fades to russet. This is one of the finest plants ever introduced.
All these Sedums areand are dividable in spring when old.
