zone 5 annuals that wintered over

7 years ago

We are having unseasonably warm temps this week. Today set a record, 74 degrees. Feeling like spring, I took a walk in the yard and discovered several snapdragons and calendula that have wintered over. Usually, I may get one occasionally, but there appear to be several. For those of us in the northern part of the country, this is the time of year we are tired of winter, so seeing those snaps and calendulas was a happy sight.

Calendulas reseed very freely so while they may appear to have wintered over, they may very well just be new seedlings emerging.

Snapdragons are fully perennial however their winter hardiness depends on specific hardiness zones and climate. In my climate, they always winter over although top growth can be killed back by colder winter temps - in my previous full sun, beachfront garden, they acted like a small shrub!!

Several websites call calendula a short lived perennial. I once had a tough one that did not mind a mild winter but lost all my seed in a move. I should like to find that strain again.

ed - found this in Wikipedia. ''Calendula officinalis is a short-lived aromatic herbaceous perennial''.

phyl- yes, several of the winter-sowers did do hanging baskets via the winter-sowing method. Just as you say, but I believe they did not start the tender annuals until mid-late April. Hardies & half-hardies can be started earlier. Do join us on the winter-sowing forum! We'll be sowing everything under-the-sun from December through April- all outdoors! (That would be the difference between "Sowing in Winter" and "Winter Sowing." One is inside under grow-lights, and the other is tossing them outside in containers and letting Ma-Nature take over. To answer the OP directly, you can take a look at the FAQs on the Winter Sowing forum to get a list of Zone 5 annuals here, but pretty much we can do most any of them- just do the tenders later than the hardies. Of course, some will perform at your house better than they will at my house...I can't grow an impatien to save my life, but have excellent luck with Marigolds & Petunias (although neither have ever reseeded in my Zone 5 yard).

Brother and Dad are right the cover wont keep the pond from freezing unless winter is very mild. I've used various deicers over the years and in Toronto Canada I have been fine with 300 watt versions and I really think that they are the best option. If a 1500 watt de-icer didn't make a hole in Zone 5a it was defective..(was it the green 1250 Watt stock tank heater by any chance? I had nothing but trouble with them getting warranty on 3 in 4 years until I got wise and stopped trying) There are other do it yourself options some use light bulbs (if you can still find 100 Watt bulbs) and others use air stones though I have found the airstone systems to be a problem in really cold conditions..

Yes, your expectations are reasonable and I think it's possible, especially if you're able to provide some winter protection. If all canes die back to the ground every year, you won't get much size-up, or it will take many years for the plants to establish. If you can bend some culms over, stake them to the ground, then cover them with a tarp or plastic for the Winter, that will keep those culms from dying -- providing you started with a cold-hardy variety to begin with. Michigan Bamboo Company might be a good place to look first. You could also take a look at the BambooWeb forum, as there are several regular posters there who are growing in z5 (not sure about z4 though).

Keep them in the garage or basement. You're at the cold end of their hardiness ranges, and they will not survive in the ground, in pots. They'll need a good long growing season to establish a root system sufficient to handle your winters...much deeper than the pots will allow.

I'm really hoping my potted "Mystic Spires" salvia overwintered - it's in the barn right now. I absolutely adore this cultivar, and I've only found it at one nursery locally in the past, and some years they're sold out of it. Unfortunately, I didn't take cuttings early enough last fall and they didn't take. So if it managed to overwinter I'll have a good mother plant. (Of course, if I see them for sale this year I'll grab them and run, but I'm not counting on actually being that fortunate.)

Just seeing anything green popping up out of the soil now is a thrill. My daffodils and tulips are coming up, can't wait to see them in bloom, that's when I'll know spring is really here.

My folks live in zone 5/6. I planted snapdragons and Dusty Miller in their beds. Most of the Dustys came back year after year (got quite large, too), as did most of the snaps -- and in the case of the snaps, we're not talking reseeds (though there were plenty of those as well).

On a related but perennial note, also have had Gladiolus bulbs over winter year after year for about two decades or more up there. This is without lifting or mulching. Some are planted up against their house, others are in a bed in the middle of their yard. Ironically, the winter hardy strain of glads I tried all died. These long term survivors are the "normal" run-of-the-mill glads sold by BBSs.

Suspect much of this success is due to persistent snow cover through much of the winter there.

My snapdragons winter through till February but the freeze-thaw-freeze-thaw cycles of March and April usually kill them. One year they made it through and grew into a bush! What a thrill. No other annual has ever made it through. I rely on reseeding which can handle the freeze-thaw. Those reseedlings are so uplifting in spring.
