Title: Mycotrophic plants that develop underground for years in Alabama
Answered by: Joe Marcus and Nan Hampton

QUESTION:

I recently heard someone say that there was a plant that took seven years to grow. They stated that the seed is in the ground but it begins the growth under ground but does not come to the surface for seven years. Can you help?

ANSWER:

We don't know of any specific plant that has a seven year root development period before sprouting, though we wouldn't discount the possibility. Because most plants require sunlight to grow much beyond the germination and sprouting stages of development, the most likely candidates to fit the description would be plants that do not produce chlorophyll. There are basically three types of such plants; parasites, which "steal" energy directly from other plants; mycoheterophytes (also called epiparasites), which receive nutrition from other plants indirectly through a fungal intermediary; and mycotrophic (also called saprophytic) plants which also have a symbiotic relationship with fungi (mycorrhyzae) but do not parasitize other plants. You can read a nice article on mycotrophic plants that includes some of the epiparasites as well.

Some well-known examples of mycotrophic plants that might develop roots for many years before emerging from the soil to flower and produce seeds are some of the terrestrial orchids such as those in the genera Corallorrhiza and Hexalectris. Spiked Crested Coralroot (Hexalectris spicata) and Autumn Coralroot (Corallorrhiza odontorhiza) are ones that occur in Alabama.
