Mary, glad your seedlings are okay!
Neal, I don't have Burma Midnight, but I have a plant that I got from Michigan Bulb Co. called Midnight, I wonder if it is the same thing? My plant is up.
I checked on my plants when I got home this evening to ensure that they were okay, it got down to 31 degrees last night, and none of them were covered. I was disheartened to find that my Hillary had multiple branches cut. I don't know if this was done by an animal or the yard folks that came to mow and clean up the yard today.
Here's my poor Hillary, several of the cut stems had buds on them 😰ðŸ¤ðŸ˜©!
