Dracula species mounting height dilemma

[Jmbaum]

Putting in a ledge in me terrarium build especially for Dracula, I’m trying to figure out best height to account for the flower spikes so they don’t end up in the water. I have 4 feet total height to work with. Will I be able to see the bloom faces is something like vampira, with that clearance? What species might you recommend that are equally impressive as Dracula vampira, but with shorter flower spikes?
