Dendrobium rigidum

This Dendrobium is also known as Dockrillia rigida.  It’s native to Australia.  This is one of my most reliable bloomers, blooming on and off throughout the year.  The flowers are only about 1/4″ across, crystalline white with nice cranberry colored stripes, in clusters from 2-6 flowers.  Whenever a new leaf has finish growing, it pumps out a new spike.  As the plant matures and spreads, the largest leaves will get to be about an inch long.  It’s very tolerant of temperature and watering schedule variations, however, it does grow best when allowed to dry before giving it a soak.  Mine happens to be mounted on some sort of wood plank, but I’ve seen them potted in clay, too.  They like a fair amount of light, but if the leaves take on a purple tinge, they’re at the high end of the light range they can tolerate.  They don’t need to go purplish to bloom, but it doesn’t hurt.

This Australian native, also known as Dockrillia rigida, is almost bullet-proof.  It blooms two or three times a year for me, whenever new leaves mature.  It’s not picky about water, neither quality nor quantity, given its succulent growth habit.  It spends the summer outdoors, and gets as much sun as I can give it indoors the rest of the year.  As long as some of the leaves take on a bit of a purple tinge, I know it’s getting enough light to bloom.  The largest leaves are a little over 1/2″ long.  The cranberry striped creamy flowers are about 1/4″ front to back.

Aka Dockrillia rigida, this Dendrobium is an Australian native.  It can handle high light conditions, which make the leaves turn reddish, but doesn’t need that much light to bloom.  It doesn’t really have any seasonality, as the leaves send out buds when they mature.  It continues to grow all year, rather than only during the warmer months.  As orchids go, this one’s as idiot-proof as they get — right up there with Restrepias.
