"Voo Doo Bulb" Sauromatum venosum's correct name: in late winter the elongated dark brown spadix emerges from the fat bulb, opening to reveal its maroon spoted interior and the slim blackish spadix whose fetid fragrance is beloved of flies. After a few days this bloom collapses--you will have probably collapsed somewhat earlier. If not already planted, plant the bulb because it will soon be ready to send up the snakeskin mottled thick stalk topped by a curved horn-like segmented leaf. The timing will be different if planted outdoors--a possible trick even in our Zone 6b gardens if the tubers are situated well below the frost line in a perfectly drained location (even if the main tuber rots during a severe extended winter, numerous bulbiles usually survive to sprout the following summer)..
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so on.×
