It doesn't grow around here, but Tillandsia recurvata is common further south. I was drinking coffee outdoors at a restaurant and the patio was littered with little twigs bearing the plants on them. It had been windy, so I think the twigs just broke and fell. I gathered up a pocketful so I could try growing some. I fall into the category of people who think they are neat and cool rather than ugly and messy eyesores
. Here's some photos of how I'm hoping to grow them. The database says they are not suitable for container growing, but I'm hoping they will latch on to the coir basket (which has a Valentine's Day orchid that went on sale after the event). I wish I had picked up more, but my jacket pocket would only hold about 1/2 dozen.
These two were the largest clumps. The biggest one is a little larger than my fist.
You can the twig behind this one. I used the twigs for anchors, but two small plants just slid off the twigs, so I just tried to work them into the coir around the wires and hope they grow attachments.
A couple more visible. Not nearly enough to give dense coverage around the container. Maybe I'll ask some friends or relatives that live south gather some and mail to me :).
Has anyone tried growing them this way? Seems like they might thrive with the same care the orchids receive - regular water and weak fertilize, hanging under the tree canopy. If they do live, don't know how they'll like inside during the winter. I'd guess probably not very much. Not many of my plants enjoy their treatment in the winter months.
