Sedum clavatum is endemic of a specific location: the gorge of the Tiscalatengo River in the vicinity of Villa Guerrero an area in the Trans-Mexican Volcanic Belt at southeast of the Nevado de Toluca in the southern part of the state of Mexico, where it grows on the slopes of the canyon.
Sedum clavatum is a particularly attractive Sedum, very appreciated for the elegance of its compact, small rosettes, up to 5 centimeters wide, whose stems tend to elongate and become creeping and prostrate, maintaining the single compact rosettes at their top and a bare, slightly wooden base. S. clavatum has a high decorative potential, as it ends up to form a succulent mat of attractive frosty-blue-green compact rosettes of tiny fat leaves.
Leaves are small, bluish-grey and lentil-shaped, slightly romboidal, rounded and thick. If grown in sull sun, they may show some pink tinges at their tip.
Flowers, like in almost all Sedums, are inconspicuous, white and star-shaped (with five thin petals). In S. clavatum, they are borne in crowded umbrella-shaped inflorescence borne by elongated stems that develop a little below the growing apex and are taller than the entire plant, tinged in yellow and red. The blooming season occurs in Spring, from mid-Spring to early Summer
Sedum clavatum is the ideal ground-covering plant, perfect for shallow, wide pots. Like all Sedums, it’s extremely easy to grow and thus it’s very appreciated among succulent lovers.
Put it in a bright spot, directly exposed to sunlight, to enhance the pink tinges of its leaves. A shaded position, along with too much water, can make your Sedum clavatum weak (the leaves may easily break) and less red: this is the so-called “stretching” of Sedums.
S. clavatum needs regular waterings during Spring and Summer, but don’t forget to wait for the soil to dry up completely before each watering, to avoid the risk of root rot. In Winter and during humid periods, thin the waterings until stopping completely to water during the coldest periods. The substrate should be well-draining and porous, with a good amount of organic matter as Sedums roots are shallow and develop mostly in the most superficial layer of the soil. This another reason, along with their tendence to develop horizontally, why it’s good to place them in a shallow but wide pot, not too deep. Sedum clavatum, moreover, doesn’t like stagnant air: it’s important to place it in a spot exposed to drafts. Regarding the fertilization, slow release fertilisers with a low to moderate nitrogen content incorporated into the potting mix will do good if applied once a year to your Sedum.
The easiest way to propagate your Sedum clavatum is undoubtely through stem cuttings, obtained by taking off the top of the stems with the rosette on it and replanting them in a porours, rich in organic matter substrate.
Sedum means ‘plant, annual herb’ in Latin. Such a generic name is justified by the wide distribution of this genus. Sedum clavatum Clausen (1975) has been only recently named, although it was earlier described in detail as the “Sedum of the Tiscalatengo Gorge” (Clausen, 1959). The species name, “clavatum”, comes from the Latin word “clava”, for “club”, referring to its club-shaped leaves.
