Well, paph potted in lava rock in Texas??
You want to water it good because you know how lava rock is, and paphs do not do well when too dry.
Quite a few of my paphs and almost all dendrobiums that are from Hawaii are potted in black lava rocks.
Well, let me correct, paphs from Hawaii are in lava rocks and some moss chunks mixed in.
Dendrobiums just straight lava rock.
It is common potting material they can find, excellent draining, but does not hold much water, which are all the qualities that suit well to their climate.
The dark one was shipped in from Hawaii.
