Mystery Bulbs

This page is a place where people can post pictures of bulbs they are having trouble identifying. Anyone who thinks they can help figure out these plants, please send a note to the pbs list for discussion. Items identified will be moved to the appropriate page once we figure out what they are.


Monica Swartz would like help identifying the following:


I bought this Manfreda sp. at the Huntington Botanical Gardens some years ago. It was labeled: "Manfreda sp. HBG 82906 YuccaDo T74-12 Sd. coll. 12/97 Mexico: Jalisco. Very dry rocky slopes". It flowered for me this year for the first time and its green flowers were unscented. The leaves are spotted when they first emerge (it loses its leaves in winter) and then the spots fade through the summer. It offsets vigorously.

The second plant was bought from the Massara's a couple of years ago labeled as an Albuca from Tanzania. Now that it has flowered, it is clearly an Ornithogalum that I would love to give a name to if anyone has a suggestion.

Rhodocodon is a genus in Hyacinthaceae that is endemic to Madagascar. I am growing four very different species and would like help giving names to any of them. This one flowers before it leafs out, it flowered at the end of April this year and then set three seeds (I assume it selfed since nothing else was flowering). The seed looked a lot like Ledebouria seeds but were already germinating in the seed pod. All three were planted immediately and are still growing well. The leaves of this bulb are always 4 and edged in deep red. Over the course of the summer, the leaves become prostrate and then die back in winter. The bulb is always exposed and has never offset or split, unlike some other Rhodocodon species. I would love it if the forum experts could identify it for me. (Note: The genus Rhodocodon was placed into Rhadamanthus. The latest taxonomic revision by Manning et al. (2004) placed that genus into Drimia along with other former genera.)
