I now feel guilty for only enjoying other's efforts, and not contributing. So, I had better make a contribution also.
Just to stay within the same Genus, here are a few Thai Dendrobiums:
Dendrobium parishii (Dendrobium papuatu x Dendrobium mohlianum). Blooms lasted 2 weeks.
Dendrobium burana green Bloomed 2 months ago, and blooms still on the plant.
Dendrobium gatton 'sunray' (Dendrobium luteum x Dendrobium illustre). Blooms lasted barely 5 days.
