I got some seeds from a friend late in the season and planted some of them anyway. They came up and are doing pretty well, but still small so I'd like to figure out a way to protect them on my roof garden, where they are now, or possibly bring them indoors to a friend who has sunny windows.
I am in New York City, and the plants are:
1. Telekia Speciosa (a great perennial that now has about 4 sets of leaves, 2-3in tall, so probably not big enough to survive the winter up there.
2. Gallardia - mature plants have sometimes survived on my roof, but not always. These are now about 3 inches tall.
3. Prairie Coneflower - I have never grown this, but got the seeds from a garden in Brooklyn and would also love to keep it alive.
Many thanks for suggestions.
