It’s been quite a floral extravaganza this spring in the dryland garden sections. Here are the latest of our flowering barrel cactus that have bloomed recently at JLBG. All of our cactus are growing outside without any winter protection in our zone 7b garden. The key for most is simply good soil drainage.

Most hardy cactus have the good sense to wait until spring to flower, but not Notocactus haselbergii. This gem, which hails from Southern Brazil, started to bloom the first of March, and will continue on and off most of the summer. It has thrived for several years in our crevice garden.
Several of our volunteers have dabbled with cactus breeding, so here is one of the hybrids we’re currently enjoying at JLBG, thanks to the creative efforts of Mike Papay. The top image is the female parent, Notocactus ottonis (yellow). The middle image is the male parent, Notocactus herteri var. roseoluteus (pink). The bottom image is the new hybrid, Notocactus x hertonis (peachy orange).
And the pricks are off…
Yes, cactus flowering season has begun at JLBG with our two earliest specimens. Both Notocactus hasselbergii from Argentina and Pediocactus simpsonii from the Western US are the first two to bloom each season. We should have an incredible cactus flowering this year, which should still be in full swing for our spring Open Nursery and Garden days.
We’ve got a thing for hardy cactus in the garden, but haven’t propagated many to offer yet. One of our many favorites is Notocactus apricus. Above is our 17 year old clump in the garden, which is 4″ tall x 15″ wide. We’ve grown a few from seed, but are curious how many folks might consider purchasing one? We’ve only been to 7F since 2000, so we don’t know if it will take colder temperatures or not.
Visitors to our spring Open Nursery and Garden this year got to see the amazing Trichocereus ‘Irridescent Watermelon’ (bred by local cacti specialist, Mike Papay) in full flower (hardy so far to 7 degrees F). Offsets are almost non-existent, so we decided to grow some from seed. Each plant will be different, but all should be quite nice. So, if we offered these as a seed strain, would you purchase some, knowing each will be slightly different?
Hardy Cactus in bloom at Juniper Level Botanic Garden
For those who didn’t get to our Open Nursery and Garden last week, here are some of the hardy cactus you missed in the new Souto Garden section. We’re passionate about hardy cactus, and have been so since we were hooked by a jumping cholla about 45 years ago. I hope you enjoy the photos of this amazing group of plants.
