Dear All: In the Dictionary of Botany, a geophyte is a plant with its perenniating buds situated below ground on a rhizome, tuber, bulb or corm. A cryptophyte is a plant with its perenniating buds hidden below ground or in water, (hydrophyte) and are more common in arctic and temperate regions. A helophyte is a marsh plant with its perenniating buds situated in the mud at the bottom of a lake or pond. While these may have perenniating buds hidden, and thus survive, only if the buds are on a rhizome, tuber, bulb or corm are they geophytes. For many years, such plants as Kniphofia and Liatris were raised mainly by perennial nurseries and not as much by bulb growers. Consequently they were often not thought of as Geophytes, even though they are. As to having non geophytes discussed I see a problem, just where would one draw the line?. The point raised by at once associating a member of a large bulb family and presuming a plant is a geophyte simply because it is in that genus is a valid point, but not germane. A geophyte does not become one by association. Cheers, John E. Bryan
