I'm planning on growing them at my greenhouse next year for sale based on what I've read on the internet

===>>>>
they are patented...

Here is a link that might be useful: link

I already knew they were patented, being a licensed greenhouse, I deal with that a lot. I didn't say I was propagating my own...I'm reselling the ones I picked up and planting a few for my trials here. I just wondered if anyone had any experiences--good or bad--with these coming back or not.

I do not know those particular ones, but my general experience is that it is hype. I live in Demmark and none of the American varieties which were declaired as hardy are very hardy here. This last winter one or two survived, but so weakened that they did not grow at all.

I'm a fan of the Mammoth Mums (orginally My Favourite) that were bred at the University of Minnesota. I had the red-flowered form survive for many years easily.

One of the keys for any "hardy" mum I recall is to plant them in late May or early June for good establishment.

the last thing i would have presumed.. based on the thousands of peeps on GW .. was that you were in the profession .. i did not intend to insult you with the warning ...

all the power to ya ....

good luck

I agree with coolplantsguy about when to plant. I had given up on mums entirely until a few years ago and then purchased a few rooted cuttings from a MN grower in late spring. By fall I had decent sized plants. By the next year, I had more than I could handle. They multiplied so well and continue to do so.

My Mammoth Red Daisey (a new one this year) is just starting to bloom. It's pretty cute.

Plant a mum in fall and its guaranteed to croak.

I planted so many zone 4 hardy mums in fall (thats when they seem to make there way out to the sale area) and they kept dying!

Finally someone told me to plant in spring...sure enough those buggers came back.

"Most" mums tend to struggle in clay soils. They demand well drained soil...although some fair ok in clay (like Sheffield).

@ whaas, it applies to many plants blooming in late autumn, not only chrysanthemums, that they survive better when planted in the spring. You can extend it to Aster amellus, Aster frikartii and others.

I've had Rosy Igloo mum for a few years and it's a great plant! I'm in a warmer zone than you so can't attest to it's hardiness. Planted in Spring. It's grown into a huge round mass of many blooms, with no pinching. I'm not crazy about the color - it's too red for my taste - if I could find a yellow I'd be a happpy camper.

The igloo does come in yellow now. They call it sunny igloo, also in purple, cool igloo. white=frosty igloo.
I have a few of the yellow here that I'm getting ready to plant out. z6 is a little warmer than here and you planted in the spring. Maybe I should get in my igloo's for spring planting. Maybe I can get some customers to look ahead that far to fall, mums are kind of a hard sell in spring... Thanks for the input everyone....

update, ALL of the igloo mums we planted came back! At my house, at mom's and my sisters, and the ones we sold to customers came back from the ones that have told me so far.
Also another cool thing, they look like when we planted them last year, nice and rounded and not too tall, not all rangy looking like traditional mums if they even come back at all. I think it's a home run.

If at all available please try the Canadian developed hardy mums. For example these shown in this link are hardy to zone 3.

here's a picture of one of the ones that came back, taken at my house.

Rouge, thank you for the information. I have never seen them here in Europe. It may take years before they come here, if at all.

The potted ones they sell in stores are ALWAYS nameless for some reason, impossible to know what they are.

I was given two thumb size plants several years ago and planted them in June in north central Minnesota. They thrived and got huge. This winter, however, we had very little snow so I lost about 75% of the plant. I get many compliments on them - they are gorgeous.

My Mammoth mums have since gotten quite large. Problem is that they flop like crazy once in bloom when it rains and it thins out in the middle so it needs dividing. This is just a mum issue in general IMO.

Obviously hardy enough after its established. Coldest winter in 30 years 2 seasons ago and 6th coldest Feb on record this year with very little snow cover.

I ended up removing most of my mums and only have one Mammoth mum remaining as it doesn't have any tree or shrub roots I have to worry about with all the dividing/thinning it requires.

Its pretty grand looking when its not flopping though. Neighbourhood women swoon over it.

I jumped on the MM bandwagon and had great success with "Dark Pink Daisy". It was so floriferous in its first year last season. But as you have noted, I experienced similarly i.e. a complete flop while in full bloom last Fall.

It easily survived this past harsh winter and it has been so vigorous this season. AND I have regularly pruned it all over thereby hoping to lessen the likelihood of another flop. I am actually debating right now whether to trim some more this week....getting a bit long into the summer...dont want to delay too long those amazzing flowers!

I have been looking for a Canadian source for either Igloo or Morden mums for my Canadian gardens but cannot find a source in Canada. Any ideas? Strange since I believe they were both developed up here!

Hi Sharon Jefferies nurseries in portage la prairie has Morden mums available in their catalog.
