- Ipomoea tarmensis n.n.
Description: Almost nothing is known about Ipomoea tarmensis, the generic name suggests, that the plant may come from somewhere in the Peruvian Tarma Province, located in the Andes east of Lima - the capital city of Peru. It is quite possible that the name is provisional (nomen nudum), and there is not any trace of this plant in literature. Ipomoea tarmensis is sometime offered on sale on the market of succulent-caudex plants, it is distinguished by indented, tomentose leaves and mauve-violet, funnel-shaped flowers with a paler throat at the end of summer. The flower is surprisingly similar to that of the African Ipomoea sp. Kruger Park. Even the hairy lobed leaves are almost the same and one might consider them similar, if not the same species (?).

The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More...
Cultivation and Propagation: Ipomoea tarmensis has the fame to be not easy at all to grow and short living in cultivation. It needs a well-drained soil mix (e.g. use a mixture for cactus + normal potting soil) with the caudex planted largely above the soil surface. A clay pot is best.
Light requirements: Give it plenty of sun or high interior lighting and freely circulating air, but keep the caudex bulb shaded. Protect from heat in summer.
Waterings: It needs regular watering during the active growing season without too much water. Let the soil become rather dry before watering again. Stop watering gradually when the stalk dries out after blooming in summer, or else the caudex may rot. During the winter months, the plant will drop all of its leaves and no water should be given during this period. Start watering when the stalk starts growing again in late winter.
Fertilization: If fertilizer is used, it should be diluted to ¼ (one-quarter) the recommended rate on the label.
Hardiness: It is supposed to be a frost tender species that must be protected in the greenhouse over the winter (Avoid any frost!). If grown in the home environment, the ideal temperatures should run between 20° to 30° C with winter time temperatures around 10°C.
