my columbine are still germinating also ! All but the one I PAID for..UGH !

If you want more blooms I would say deadhead...if you are more interested in seeds, then let them go to seed. Last year I didnt worry about collecting seeds, so I deadheaded and got more blooms. This season, I deadheaded some, and allowed some to seed, so I can trade.

Good luck with the plants ! Sorry the delphinium and larspur didnt grow for you..I havent done them from seed, but I am SURE someone will have info for you.

I deadhead my columbines and have them blooming all summer. There are fewer blooms than the spring but still nice.

Columbines can be very slow germinating. Kept a container through the winter and even have a few new sprouts this spring.

In the past 2-3 weeks, I've actually continued to see germination in a few of the containers that still remain (which isn't that many - most of the seedlings are planted out or they were transplanted into small pots).

I've gotten new sprouts in the Yvonne's Salvia, Aster laevis, Aster novae-angliae, Nodding onion, and Northern sea oats grass (which has germinated so much slower than the other grasses).

My Columbine is still stuck at 3 tiny seedlings. They are growing sooooooo slowly. I'll leave them, good chance some more sprouts will appear.
