Yes, put them in pots and put them in a bright window - they will be fine.

Thank you for your response Ken. Sorry I wasn't clear about what I did when I shifted them. I lifted the original root "balls" (not tightly packed) out of the old pots and put them into new pots filled with Pro-Mix, then flushed the new pots in hopes of removing the remaining salts or whatever. When I was devising my plan, I did worry about too much moisture and too large of pots, so I downsized the new pots a bit. The old pots and media are sitting out in the hoop house while I debate whether it's safer to dump the potting mix in the garden or in the alley. I'm thinking the alley, lol. It's interesting that Bleeding Hearts come up late in your area. One of the main causes of failure in Cheyenne (6,000'+) is they come up way too early (maybe April or so) and get hit with fairly hard frosts, often through the middle of May, sometimes through the first of June. Mine are on the north side of the house and don't wake up nearly as early as some people's do. Even so, they get flattened every few years. Our nighttime temps aren't reliably above 50 degrees until July or August (though the day temps do average 80-ish then), which is why I was wondering if I might need to give the seedlings a chilling. I do like to winter sow many of the perennials I want for my own yard. Much less work! For our spring plant sale, though, I start a variety of perennials in the fall or winter. The foliage tends to stay pretty low. I'm supposing it doesn't get leggy in the short winter days (no supplemental light for these guys) because the temps are low, too. The roots, on the other hand, seem to grow really well. Potting things up as the roots start showing out the bottom (not on stuff like Mirabilis multiflora or Callirhoe involucrata - yeesh!) keeps me busy. If we get any warmth in April, the foliage usually catches up to the roots in time for the sale. Oh, nope, no extra seed. I collected it in 2011 or 2012 and promptly forgot about it. I didn't have much hope they'd even come up, and figured I had nothing to lose :) Depending on the weather, my projects are either in the east-facing patio we enclose in the winter (sun from the north, east and some south) or in the west-facing sun room (sun from the south, west and north). When it's 20-something below zero at night, the patio is 20-something below, too, lol. The coldest I've seen the sun room this year was 7 degrees above zero. I bring things like geranium and dahlia seedlings in pretty much every night. The hardier perennials may or may not come in if the weather is supposed to be mild. So, long story short :), it sounds like if we ever get some warmer weather, the Bleeding Hearts might wake up and get back to growing :) Thanks again!

Thanks for your reply ~ do you happen to remember the name of this particular Lamium? I need to dig up a couple of Undulata Hostas (I suspect HVX Issue) & wish to just cover the area w/a few more silvery looking Lamium. BTW Is the *Gold Heart* boosted up or really a tall BH? The one & only I have, is the white spectabilis that keeps her string of hearts for a long time & is still doing great ~ she produced her hearts at the same time as the Daffodils flashed open. Some of the earlier heart are turning to seed pods now as well! I have a 3 babies around the mother - I suppose I could relocate them at this point right? TIA

Well, its counter to the method & ways i've had great success with & that's to pot up first, then place in direct sunlight & lightly fertilize the roots at least once until growth appears. Once growth appears let it grow in sun until it just begins to get hot & then plant it in the shade, carefully, as the roots are brittle & so is any new growth not yet above ground yet. Keeping well watered if inadequate rainfall, helps it to keep it from going dormant earlier, especially if it gets hot before or during start of summer, too. Trying out Dicentra 'pink' this year, but bought early while peat in baggy was still moist & have a few flowers now. I'm in coastal Virginia & its been rather warm lately and they're doing fine..Make sure the tops are upright, when planting also...
