I've got a plant that I got from local grower that was labeled as D. filiformis filiformis, but I suspect that it might be a D. hybrida. This grower also had a ton of D. intermedias growing. The plant in question has leaves about three to four inches long and the flowers seem to be awfully white. How does one determine if it's a filiformis or a hybria?
All information would be GREATLY appreciated!
