I have green, and a red/purple/green species available by the strand/cup, enough to start your own colonies (I chop mine up to 1-inch segments so they multiply faster).
Limited quantities! They grow slow!
Instructions for growing: http://bluegrasscarnivores.com/ (I basically give it lots of diffused, bright lights; give it high humidity; grow it on New Zealand long-fiber sphagnum moss substrate; and flood it with distilled water once a week)
Photos on the left show what it looks like when you get it. Photos on right show them after a month. I only have been growing them for a couple months so no photos of them growing longer than that.
$8.00 for 15-20 1-inch strands, or $15 per cup.
Green. Slow/Medium grow speed.
$6.00 for 15-20 1-inch strands, or $10 per cup.
Green. Medium/Fast grow speed.
$12.00 for 15-20 1-inch strand, or $20 per cup.
Red/Purple/Green. Slow/Medium grow speed. Needs lots of sun for red color, takes about 4-6 months to become red. RARE TO FIND.
Updated pricing because moss are not fast growers, but when they fill your pot it makes it worth the effort.
Plus $3.50 shipping.
