Winterizing roses in whiskey barrels

Hello. I have regular roses planted in whiskey half-barrels. To keep the bushes from freezing, since they are aboveground, I thought to wrap the barrels in a couple layers of bubble wrap and then black plastic, and mulch them thickly. Does this like a good idea? Do you have any other ideas?

I live in Northern Colorado, and I like my garden to be just full of coneflowers.

Since you are an expert on this which method is better to germinate and plant coneflowers:

1. To put the seeds in the ground at the end of Fall or beginning of winter.

2. To stratification the seeds by putting them in fridge during wintertime and plant then in the ground in Springtime.

Thank you so much for your kind help.

Wishing you all the best.

Digital Pressure Cooker above 7,500 Feet


Just bought a Breville BPR700 digital pressure cooker....which has a maximum operating pressure of 12 PSI [0.8 ATM]. It has an automatic altitude compensation feature, but it has no settings above 6,000 feet and the manual clearly states: do NOT use cooker above 6,500 feet. Reason: under-cooked food ? Explosion hazard ? Is there a work-around ?? My altitude is 7,750 feet. Thank you !!
