Dendrobium secundum, also known as the toothbrush orchid, is a species of flowering plant in the genus Dendrobium of the family Orchidaceae. The common name refers to the fact that all the flowers are on the same side of the stem, much like the bristles all on one side of a toothbrush.[http://www.orchidspecies.com/densecundum.htm IOSPE orchid photos, Dendrobium secundum Lindl. 1828 J.J.Sm Photo courtesy of Eric Hunt, plant grown by Eddon Orchids] photo; common name explained in caption

the Dendrobium secundem lives wildly in more tropical areas like above, and the flowering times may differ depending on temperature, water, sun/shade and climate. If you look after it well it has one season where it grows, then opens its flowers.
