I have had that one for a few years, but it died this last winter at only -3.8 F. It was not very big and may have done better if it was larger?
There is a hybrid that does much better in the cold and looks almost the same. Cylindropuntia kleiniae x imbricata it can be bought from Plantasia Cactus Gardens lorton1@msn.com The owner is LaMar and is a very nice person. He has been growing many sp. of cactus in Idaho for years. Ask him for a catalog 🙂

Thanks. I have emailed for a catalogue. I may have to do more research if yours did not survive -4F.

I got the catalogue. Most of the cacti are either very similar to the opuntias that I have or way too tender for my area.

I was considering getting some chollas that would have had to come in most if not all winters. But the shipping and the phytosanitary certificate ($40) just made the cost too high.

I'll stick with my new yuccas and maybe add the odd new cactus later.

His chollas have been found in the colder areas where the species are found. He has tried many deferent kinds and have been growing them in a zone 6 for years. Some are very hardy and may survive in a zone 4?

I would feel better about buying a zone 6 cactus from a zone 6 area, then a zone 4 cactus from a zone 9 area 😉

What is a phytosanitary certificate?

A phytosanitary certificate certifies that the plant material is free of bacteria, viruses etc that are prohibited from entering Canada. It is required for all live plant material entering Canada from any other country. The US government requires them as well for plant material entering the states.

The selling nurseries arrange for them and usually charge what the certificate costs(normally between $15 & $25). Plantasia's cost $40 which when combined with about $20 for shipping makes $30 in unrooted cuttings pretty expensive. Either he doesn't get them that often or there is something unusual about cacti. I was tempted to ask him to throw some cuttings in an envelope and call them 'promotional pens value $nil' and I would take my chances on having them destroyed if customs caught them. BUT: It is illegal and he is taking a risk that could affect his nursery business and I could not ask him to take that risk.

Instead, I will spend the $ on several Rhododendrons and wait to see if the local experimental garden has some cuttings available this summer after they have met their committment to other experimental gardens. The last thing I would want is 'Walmart hardy' cacti from somewhere in Texas or Florida.

Sorry, I did not know that it was so expensive to ship to Canada. His cutting are usually 3-5 dallors here?

I have been shipping things up there and have not had any problems yet? I will check into that phytosanitary certificate. Thanks 🙂

I appreciate you checking. Most of his cuttings are in the $3 - $5 range. I had planned on getting 8 or so instead of 1 or 2 because of the shipping and other costs.
