In Austin, the chances are good that your festive poinsettias originated at Marbridge Ranch. Even if you’ve never seen the garden center yourself, your poinsettia probably has. I haven’t been to Ventana del Soul since the weather changed. At that time there were houseplants from Marbridge for sale there, so I bet that now there are poinsettias. Maybe this weekend I’ll have a minute to stop by and find out. At any rate, even without trying to acquire them, already I have three Marbridge poinsettias so far this season, all red, all gifts. Marbridge is as much an Austin holiday tradition as cerveza Noche Buena and displays even more poinsettias.
