Any one out there growing this one in a cold climate, say a zone 7 or lower?
Any one growing this one in Idaho?

I am so happy I am finaly the proud owner of Echinocactus polycephalus. It is a small plant but that is alright In the future I will try growing this one for sell, becuase it is a very hard plant to find, even the seed was hard to get a hold of. I have not tried to grow my seeds yet, but will give them a try soon.

That's awesome Aaron. What's the hardiness of it?

I am not sure how hardy it is? I do know that aleast 2 other people have grown this plant in Idaho over the past 4 years. I think I will cover it up this first and maybe the secound year. The seed of this plant comes from an area where the plants get very large, hard to tell from fero barrel cactus.

hardy if kept very dry in winter, been through 3 winters

Maybe only 2 winters?

Aaron did your seeds ever sprout? According to my 'cactus bible', the Polycephalus is hardy to the authors zone 5 without covered protection; just good siting I assume. The author also states that the var. xeranthemoides is even more cold hardy than the sp. polycephalus. Food for thought.

My polycephalus have not sprouted yet.

Still waiting.

I did have a few seeds sprout, but I let them get to dry when very little and they died. I would be very weary of them living through a zone 5 not covered, but I'm sure it's possible. I believe there is a few different forms or subspecies out there, and I'm sure they all different cold tolerances. And to mention they are very expensive. I will always cover mine, helps keep them dry in winter. If I had a bunch of seedling I might grow a few for trials.

Up date.

Mike,

This might be good info on starting the seed, and what I will try, if I ever get more seed.

Awesome thank you! I got my seed here: http://www.ebay.com/itm/171068594671?_t ... EBIDX%3AIT

No polycephalus yet but I did notice today my Echinocereus Reichenbacii var. perbellus and Ferocactus Wislizeni sprouted so I am kinda stoked about that.

Thanks, was looking at that the other day.

Did you look here?

Counted 4 of these today. The Polycephalus finally sprouted.

Right on! You've got more to sprout than I ever have.

Jim,

Thanks for the link, I just bought a few from there.

Now to test my patients of waiting for them to grow to a decent size

Cool...glad it helped,I considered it but needed to keep
my spending in check for now

Post a pic when you get it planted.

I like growing from seed too but I am not
getting any younger here.

I am not as old as Jim but I could not wait on seed either. I really want something now.

neat cactus!

Live plants are sooo expensive! Will try to look for the seeds coz it's looking awesome, Aaron!
