Succulent Sunday: Plants That Look Like Pebbles

Pachyphytum oviferum (left) and Graptopetalum amethystinum 

Look at these turquoise and pink pastels! These soft colors belong to a pair of living confectionary, species of Graptopetalum and Pachyphytum, which are members of Crassulaceae or the Stonecrop Family. They look almost edible, but these plants are treats for the eyes, not the mouth. Their thick leaves and soft stems evolved to store moisture as a hedge against drought and high daytime temperatures in their native Mexico. Part of the charm of these plants is the powdery (in botany, pruinose) coating on the leaves, which unfortunately is also easily smudged -- shown by the fingerprints on this G amethystinum.

Besides Pachyphytum and Graptopetalum, Mexico has several more genera of succulents which are all closely related, and are all capable of interbreeding or hybridizing: Echeveria, Sedum, and Cremnophila. Similar but more distant relatives include the common "Jade Plant", Crassula ovata, originally from South Africa and grown as a houseplant worldwide. 

MadProfessah says, "I just like them because they're pretty."

Succulent Sunday: X Sedeveria 'Harry Butterfield'

X Sedeveria 'Harry Butterfield'

(The reason for the strange genus designation, X Sedeveria, is that this is a transgeneric [cross-genus] hybrid between the genus Sedum and Echeveria.)  

This hybrid [in the photo] is just starting to show its potential to grow into long chains which tip over and hang like an animal's tail. This is a cross between two classic Mexico members of the stonecrop family (Crassulaceae), Sedum morganianum andEcheveria derenbergii. It's nicknamed "Super Burro Tail" because it's fatter and more robust than its hybrid parent nicknamed "Burro Tail", Sedum morganianum.

Succulent Sunday: Cotyledon campanulata

Cotyledon campanulata

By popular demand, Succulent Sunday returns! Here's some information on this gorgeous specimen:

Tiny hairs glisten on pale-green fingers, each tipped with a red crease -- Cotyledon campanulata from Eastern Cape Province, South Africa. Tall flower stems shoot up in late spring from which yellow flowers hang like little bells, except the petals are splayed wide open (unlike its Cotyledon cousins).

From a recent paper, "The only other species possessing cylindrical to urceolate shaped flowers, C. campanulata, is sister to a grouping of four species (C. velutina, C. woodii, C. barbeyi, and two varieties of C. orbiculata) that all share an erect growth form. Cotyledon campanulata is a decumbent, dwarf shrub (up to 20 cm) with yellow flowers that, like C. cuneata, are viscid on the outside of the corolla. However, C. campanulata has smaller flowers and is much more narrowly distributed, present only in a small region of the Eastern Cape Province of South Africa."
