Dendrobium cuthbertsonii is one of my favorites also and it has many color forms. The flowers are among the longest lasting of any in the genus, and in fact the plants can bloom themselves to death. They are quite sensitive to any chemicals, and if you get scale or mealybug problems the plants will succumb. They are pretty easy to grow, however, and quickly get to nice sizeable clumps.
...those leaves are really cool too!
Do they need a chill to bloom?
Thanks!
Yes. They originate from mountain region of New Guinea. They don't like heat and need intermediate - cool temperatures, ideally with 10 degrees difference between day and night temperatures.
