and P. veris-
By contrast, here are the same age seedlings that have been kept under lights all winter. They are noticeably smaller. A few still have good color, some were underwatered and died, and one looks pale, not sure what is going on with it. I'm in the process of putting them in sheltered outdoor conditions on my east-facing front porch to get them ready to start growing with the warmer temperatures of spring, then I can observe further how the two over-wintering methods compare.
Another nice surprise is that the Meadowfoam, Limnanthes douglasii, seedlings that I noticed last fall, which had self-seeded themselves from the plants that I grew last spring, have made it through the winter unscathed.
Here are a couple of Achillea that have been under lights, one looks actually comparable in size to the outdoor plant but partially dried out, the other dried out and died.
I also tried to start some plants from cuttings last fall, here are the ones that survived, some roses and Santolina-
This is not a very good photo, taken without flash, but of Vernonia (Ironweed) seedlings with pretty good growth. One dried out and lost its leaves but stayed green so I think it will get some new leaves when planted out. It will be interesting to see if the early start will be enough for them to bloom this year, I haven't grown them before and they may like more watering than I usually give plants in my dry season.
The final surprise outdoors was the first bulb coming up, Galanthus, Snow Drop,
I planted a few more new bulbs last year and am looking forward to seeing them bloom. Meanwhile, I am now starting seeds of annuals and perennials, a few are chilling in the refrigerator for a month or two, and the rest are already coming up under lights. It is so cheery to see little seedlings coming up when the garden is pretty bleak outside.
