Not strictly an orchid show, but there will be some... You might be interested anyway.
The Michigan Bromeliad society is having its annual show this weekend (Sept 10,11) at the Matthaei Botanic gardens. If you need directions, drop me a line.
Many bromeliads for sale, and we have joined forces with the succulent society and maybe even a few other plant groups, I've kind of lost track. I don't know how many people will be selling, but it will be more than the usual bromeliad show crowd. I'll be bringing broms, a few orchids, and my usual assorted array of common and unusual tropical plants for vivariums. I'll be bringing home small bromeliads and unusual tropicals for myself, of course. Hopefully fewer and/or less space requiring than what i sell.
