In this sub-family, the most important a mteresting plants are to be found in the ger Sedum.

SEDUM. There are approximat 5oo species, endemic to the European Alps, A; Japan, Africa, and the Americas, and varying fr« compact to shrubby forms. Many are hardy Britain. It is the non-hardy plants, however, that usually grown in indoor collections. They m; ideal beginner s plants, growing in full light and 81 A good all-round compost consists of 4 parts Ios 1 part each of sharp sand, broken brick, and mortar rubble. They should be frequently wate in summer and about every 2 or 3 weeks in Sedum dendroideum. Mexico. Grows to quit large bush, with shiny green leaves and she yellow flowers.

Sedum pachyphyllum. Mexico. A small shrub-1 plant with club-shaped leaves, greyish-green wit lighty waxy covering, and with a reddish tinge the ends. The flowers are yellow, and arise compact bunch.

Sedum Pahneri. Mexico. Forms rosettes on ends of the branches. The leaves are grey-gr with rounded tips, the flower orange-yellow.

Sedum Stahlii. Mexico. A very beautiful ph with oval leaves dark green to brownish-red.

Numerous slender stems, intricately branched, are more or less prostrate at the base of the plant. It is easily propagated from leaf cuttings.

Sedum Treleasei. Mexico. Thick leaves, curved somewhat upwards, pale green, with a delicate blue-grey covering. The pale yellow flowers are united in an erect umbel.

Sedum Adolphi. Mexico. Forms a small shrub, with fleshy leaves and branches. The leaves are alternate, more crowded towards the tip, yellowish-green with reddish edges. The white flowers appear in March and April.

Sedum dasyphyllum. A small tufted evergreen perennial from Europe and N. Africa. It has, however, become firmly naturalized on old walls in various parts of southern England. Easily recognized by its tiny growth, egg-shaped and very fleshy pinkish-grey leaves arranged in opposite pairs, and its dainty small pinkish flowers on two branched free-flowering cymes. The plant much dislikes moisture, but is very easy to grow. There are three varieties, all of which are nearly hardy.

Sedum kamtschaticum. NE. Asia. A glabrous plant with a stoutish root stock from which many-branched shoots spring. The shoots end in leafy cymes of large, rich, orange-yellow flowers, which appear from June to September. It rarely exceeds 6 inches in height.

Sedum lineare. China and Japan. A rather straggly glabrous evergreen species. There is a stronger growing form, S. lineare robustum, with grey-green instead of bright green leaves, and paler coloured flowers; also a pretty form, S. lineare variegatum, which has a margin of white surrounding the narrow leaves, pink stems, and is robust in growth. The latter variety is often met with under the name S. sarmentosum.

Sedum Sieboldii. Japan. A very lovely plant, often used in hanging baskets. It has carrot-like tubers, and dies back in winter. In late spring it sends up lengthening shoots with roundish stemless leaves in threes. These shoots terminate in flat umbels of rosy-purple flowers, which are very attractive against the glaucous leaves. A variegated variety is perhaps the more popular. It differs from the type in having a large area of chrome yellow in the middle of each of its blue-grey leaves.

Sedum spathidifolium. Although this plant is quite hardy, it is very attractive when grown in a pan. A native of western N. America, it is evergreen, glaucous, forming close mats composed of flattish, fleshy-leafed rosettes. If grown in a sunny spot, the leaves become tinged with red. In May and June, yellow flowers appear which are half an inch in diameter. The variety Cassa Blanca makes a very attractive little plant, rather more miniature than the type, but with the rosettes so heavily covered with a whitish farina as to cover completely the glaucous or red colouring.

Sedum Chaneti. China. A very striking plant. Forms rosettes of fleshy, glaucous, spine-tipped leaves, the rosettes being of varying sizes. On full-sized ones, ascending spires burst into dense little pyramids of white blooms, with deep purple anthers. Flowering period, September and October.

Sedum altissimum. S. Europe and N. America. A very distinct species with a strong alpine-growing habit. The many-branching stems are thickly set with sharply pointed fleshy leaves, which are flattened on their upper surface and of a greenish-white hue. The flowers are greenish, or greenish-yellow.

Sedum cauticolum. Japan. A lovely species. It has distinct affinities with the well-known S. Sieboldii, but differs from this by carrying its leaves in opposite pairs instead of whorls of 3. The rosy-purple flowers appear from September onwards.

Sedum multiceps. Algeria. Has free-branching stems that become brown and woody, the short branches densely furnished with linear fleshy leaves. The flowers, inch in diameter, are bright yellow.

Sedum pulchellum. America. A desirable bright green tufted plant with linear leaves densely arranged on reddish stems. The inflorescence may be up to 4 inches across, and consists of from 3 to 5 recurving branches which radiate from a common centre. One solitary flower grows in this centre, and the rest of the flowers are disposed along the radiating branches. They are bright rosy-purple.

Sedum Morganianum. Popular name “Burro s Tail”. An interesting plant, ideal for hanging baskets, producing long stems tightly packed with grey-green leaves. Easily raised from leaf cuttings.

Sedum guatemalense. Looks like a smaller edition of £. pachyphyllum but the leaves are deep green and very shiny; if the plant is kept on the dry side, and in the sun, they become a bright cherry-red. An excellent plant for beginners. Easy to propagate from leaves or cuttings.
