I'm in northern Virginia zone 6B (near DC). I start my seeds inside under lights and in a sunny picture window and move them onto the glassed in porch when temperatures won't be too low then into the garden beds starting some time in April.
The last two years, I've been starting them almost a month earlier than I used to - end of January, beginning of February now. Last year, for the first time ever, I saw bloom on a newly planted seedling. This year, so far, I'm going to see it on four (out of 450 or so seedlings). Since we have several more months until frost, maybe there will be more. This adds up to 6 to 7 months from seed start to bloom.
For those of you who hybridize much further south, is that a normal amount of time to see some things bloom from seed?
