I'd love to get lots of the Dark Knight delphiniums and even some of those Red Carolina delphiniums.. I have found seeds for sale, but I know that sometimes plants don't grow from seeds. Anyone ever tried it &, if so, results?

I've wintersowed them. They didn't do well- knocked down by storms.

It's not too late to wintersow. In fact, WSing season starts on winter solstice, which was just about a week ago. I use the method all year long. If I know something is supposed to require cold strat, I do it in winter. But if I have very fresh seed, like just harvested from my own yard, I sometimes sow them whenever I get them. If seed is that fresh, it's pretty easy to germinate. Generally, if cold strat is recommended, it is because that cold is needed to overcome dormancy. If seed is REALLY FRESH, it often doesn't have time to build up that resistence to sprout and no cold strat is needed. But I wouldn't recommend that unless you have just harvested seed.

This is what Clothier says about delphs
Delphinium belladonna, cardinale, cashmirianum, chinense, elatum, glareosum, glaucum, grandiflorum, nudicaule, patens, requinni, and tatsienense , Sow at 22-24ºC (71-75ºF), germination in less than 2 weeks

Delphinium exaltatum, and zalil , Sow at Max. 5ºC (41ºF), germination irregular, often several months

I have grown delphiniums from seed. I just did it indoors under lights. I got a very good germination rate, but they were particularly susceptible to damp off. If I remember correctly, they had to be started in the dark.

I've grown them from purchased seeds and also from collected seeds.

It's a very common problem with growing seedlings, especially indoors. I've only seen it rarely since I use sterile potting soil and I did this years ago before I was using Promix. The seedlings die off by dieing at the ground level. I probably had the seedlings way too overcrowded since I had a very good germination rate and not enough air circulation.

I still ended up with a lot of delphiniums. I think I had the best germination with collected seed that I stored in the fridge over winter.

Toni, your comment makes me wonder if you are aware of the basics of wintersowing. Sounds like you might be thinking it is sowing seeds directly into the garden in winter?

We are talking about sowing seeds in covered, vented, recyclable containers, with drainage holes, and putting those outside in the elements in winter. My containers of choice are milk jugs.

I might have misread your comment, but, in any case, I consider snow a normal part of wintersowing. You don't have to see the ground, as long as you can get out the door and stick a jug in a bank of snow, all's well.

gack! My comment never showed here!

Karen - You're 100% right, I haven't a CLUE on wintersowing. When is a good time to do it? Can I use the plastic containers that plants from a nursery (1-2quart) come in? What kind of soil? Can I plant any kind of seed? This is SOOO exciting!!! Smiling :) Smiling Sorry, I'm a moron...

I have planted delphiniums from seed successfully, too, although I also started mine in my GH. Had some in a big pot and am anxiously waiting to see if they survived being stuffed into a big raised bed this past fall. Damping off is a fungus problem. Don't know if that is a problem with winter sowing? I'd still used sterilized soil if it was me doing it. Smiling

I've done a lot of winter sowing by just planting the seeds in flats in good quality seed starting mix like Promix, putting clear covers on the flats and putting them in the shade on the back porch around February or early March. I've never done delphiniums that way, but I've had excellent results for papaver somniferum, various penstemons, pansies, and other stuff I can't remember right now.

AND, about that damping off, I finally remembered and tracked down that tip that Shoe posted about using cinnamon to help prevent damping off:

Hey Toni, I'm a first-time wintersower, too!

I learned a lot from reading the FAQs on this site:
http://wintersown.org/

I won't be growing delphiniums, but I'm going to try about 10 different seeds. It's so exciting!

I WS'd some delphs last year for the first time. They were blooming by summertime. Big Grin They didn't seem any more difficult than any other seed, though my container soil did develop some green fungus (?)....at any rate, it didn't seem to bother them. Delphs even seem to enjoy heavy clay...

Toni, I read you right! I didn't think you knew what we meant.

Wintersowing starts on winter solstice (Dec 22). I use the method in summer too, with slight modification.

While gardeners have used some form of wintersowing since the beginning of time, it was Trudi Davidoff of Long Island who really made this wonder widely known on the internet around 10 years ago. She also pushed the method of using recycled containers like milk jugs. The wintersown.org site that ssgardener mentioned is Trudi's site. Definitely read it, then come back with questions and we'll be happy to help you. Don't miss the FAQ and Trudi's offer for free seeds. Yes, they're really free.
http://wintersown.org/

Nursery pots work, but best to cover them with clear plastic. It Works as a mini-greenhouse. In your climate (altitude) you'll need lots of vents to prevent overheating. And seedlings need head room to grow- keep the plastic up off the soil. They must be vented on top and have good drainage in the bottom. Use good potting mix, NOT SOIL. I highly recomment 3" of soil. Less will dry too fast. Poke more vents after they sprout, or remove the top. Recover for late frost

Best thing about wintersowing: no damp-off. While I do sterilize soil and containers for indoor sowing, I don't do any of that for wintersowing. My potting mix isn't sterile. And I don't even wash the milk jugs- I just rinse out the milk.

So see Trudi's site, and come back here with your questions. Many of us wintersow and we'll be happy to help you.

Karen, I've been reading as much as I can on wintersowing, but this is the first I'm hearing about keeping the plastic off the soil. Do you mean we should place the containers on paved surfaces and not grass or dirt?
