Here's a bit of advice that actually works. I know it's hard not to immediately unpack your plants and get them into the substrate, but . . . Warning Will Robinson! Unpack you plants -- all plants -- especially those from the LFS and dump them into a big plastic bucket of two or 3 gallons of treated water with the addition of a tablespoon per gallon of alum. You can find alum in the spice rack at the grocery or at your LFS. Let the plants soak over night (24 hours). Rinse thoroughly, soaking them in several changes of clean treated water. Then plant. If the plants are good healthy stock they will easily survive and any members of the mollusk family will not. Snail-free plants.
As for the crypt wenditii, I keep seeing many crypts identified as wenditii, but they range from lush green to dark bronze and deep brown/red. I ordered 10 (minimum quantity) with a large order of other plants from azgardens.com. They varied in size but were the size of amazon swords with thick, healthy roots. They were described everywhere I researched as "A good foreground plant." Actually, they're better as mid ground plants. And after four months not only are they flourishing but they compete in size and attention in front of two prize swords I'll have to move. And the swords are not small plants. Still, I'm content. Better to have healthy plants and not complaining than wasting money on plants that fail. They are stunning.
There are several sizes of this same variety of wenditii. It may be worth a call to the business you plan to order from and make sure of what you are getting. Good luck.
