Us folks in colder climates are always limited in what we can grow outdoors… cause of this thing called “A FREAKING HORRIBLY COLD SNOWY TIME OF YEAR THAT CAUSES DEPRESSION AND THE NEED TO HOLE UP IN YOUR HOUSE”, better known as Winter.
Slowly but surely, I plan on trying to see if other North American species are hardy outside here. I haven’t tried any North American pinguicula yet. My friend in Virginia grows them outside… and he gets cold, So its something I’d like to try. Anyway, that’s for another post.
What you are looking at in the photos is Drosera binata. This species and all its forms have proven hardy here in zone6B. They die to ground every year, but come back from the roots. I don’t know if that’s what happens in their native habitats (Julian?), but they don’t seem any worse for wear. I’ve grown these outside for eight years now… and never had an issue! They produce copious leaves and flower prolifically! I don’t know if they will reproduce from seed, I’ve never let them seed! I always cut off the stalks. Maybe this year I’ll leave them and see what happens 🙂
