D. tubeana is from Ecuador and has been found at a wide range of altitudes from 75m and up to 2400m.
This is a temperature tolerant species since it has been found at surprisingly low altitudes but as with all Dracs keep the RH above 80% especially to avoid bud blasting!
The leaves are 4 - 5 cm (2") broad and about 20cm tall (7 3/4"). D. tubeana carries one of the largest flowers of the genus, almost 25cm (10") tail to tail!
I grow this one in live Sphagnum moss and I use an open basket since the inflorescence grows into the compost.
