A majority of orchids are perennial epiphytes, which grow anchored to trees or shrubs in the tropics and subtropics. Other species are lithophytes, growing on rocks or very rocky soil, or are terrestrial. Nearly all temperate orchids are terrestrial.
Some orchids, like Neottia and Corallorhiza, lack chlorophyll and are unable to photosynthesize. Instead, these species obtain energy and nutrients by parasitising soil fungi through the formation of orchid mycorrhizas. The fungi involved include those that form ectomycorrhizas with trees and other woody plants, parasites such as Armillaria, and saprotrophs.[5] These orchids are known as myco-heterotrophs, but were formerly (incorrectly) described as saprophytes due to the belief that they gained their nutrition by breaking down organic matter. While only a few species are achlorophyllous holoparasites, all orchids are myco-heterotrophic during germination and seedling growth and even photosynthetic adult plants may continue to obtain carbon from their mycorrhizal fungi. |

Hi, Roberto. Wow these orchids have such a saturated red color. Nicely composed a feast of color with a complementary dark green frame making the red more intense. Good presentation and information on orchids. Cheers and TFS.

Ciao Roberto
I like this intense red
is strong and beautiful, as I like!
Good details in the red petals,
and the subject stands out well on the dark background ...
Beautiful orchids ...
Greetings,
Sergio
