Echinocereus knippelianus var. kruegeri

This squat dark green, nearly spineless cactus is found growing at over 6,600' (2000 m )in elevation. It's native habitat is the Sierra Madre Oriental Mountains of Mexico. It is found growing in semi-shady sights, at the base rocks and pines. The root is thick and tuberous. In the heat of summer this root can pull the plant down into the soil as protection.

I have grown it for five years now with no winter damage. It is always the first Echioncereus cactus to bloom for me.

John, a cool cactus!  In flower it almost looks like Lewisia rediviva.  From looking at the links, I see that it shades to deeper pink forms too.

It's funny how our "want lists" keep growing and never seem to shrink. ;)

You said it, Martin!

For us to grow it successfully here in New England, it not only has to take our temperatures, but it has to take the moisture, particularly at the 'wrong' times of the year. Does anyone have any experience growing it successfully outdoors in a relatively wet climate like New England?

I would love to see what other cactus treasures, you have hiding in the cracks and crevices of your garden.

Pediocactus winkleri, grown from Mesa Garden seed in 1992.
Then some form of Cylindropuntia ramosissima. I don't really ask what's special about the form, I simply acquire without a second thought.
Then, an obviously fatal test of the hardiness of Maihueniopsis glomerata, in a tray filled with gymnocalyciums. It didn't lose moisture like it should have, and froze, and that was that.
And Maihueniopsis darwinii, in a tray with more gymnocalyciums. (Like G. bruchii, calochlorum, etc.)
Finally, a totally cool, who-cares-if-it-ever-flowers hybrid of Echinocereus coccineus and E. moricallii. Also in a tray. I picked up four of these hybrids and this is the only one that survived.

The Pediocactus winkleri is indeed a gem. I hope it sets seed for you.

The Clyn. ramosissima is the spineless form. I guess that makes it some what special. They are one of the slower growing Cylindropuntias around. I grow both the spineless and spined forms but neither is very large yet.

Gymnocalyciums are way cool too, I have tried a couple and lost them. This year I am trying Gymnocalycium chubutense.

Maihueniopsis darwinii is hardy for me also. I planted a start of Maihueniopsis glomerata var. platyacantha last spring, it seems to be ready for winter it has dehydrated and shrunk by about half.

The Hybrid Echionocereus looks really cool. It took me a while to track down the E. moricalii parent. I found it listed as Echinocereus viereckii subsp. morricalii. If it blooms any thing like E. moricalii It will be a stunner. The spines on your plant are great all by themselves.

Winkleri has set seed, and I just ignore it. Typical for me.
I picked the Maihueniopsis at random from Mesa Garden's list; I figured glomerata should be hardy but maybe this was a less hardy form. (or, I didn't pick one of the hardy forms.) It didn't even bother to begin to lose moisture; it just froze solid. It was rock hard after the first freeze, not even the slightest bit of yielding to pressure when I prodded it with my fingers. (I still do that though I know it's stupid.)
I was afraid it would explode.
M. darwinii has been here in the ground for a while, but this is the first time in a tray. The trays have to perch on the ledge of the flagstone patio because if they sit on the patio itself they're in the shade and can be covered with snow for a month, and that's fatal. I lost some Echinocereus coccineus that I knew for sure were hardy, that way. Mush by January.
