Visited on 25 May 2008, the Sunday before Memorial Day. Not many people there, so it was a pleasant stroll with my SO and our camera; still there wasn’t nearly the variety and quantity of plant life I’ve come to expect from such a place. The heart of the US is a beautiful place in and of itself; you likely won’t find much advantage to visiting Powell Gardens. If you desire to, however, it may be more pleasant to visit in the late summer than the late spring.
