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.
Spring is unquestionable peak cactus flowering season at JLBG. Although many of you are familiar with our large opuntia (prickly pear) collection, we thought we’d focus on the more diminutive barrel cactus, which you will see if you visit during our spring open house. Keep in mind that most close at night, not reopening until 10am-noon the following day. The photos below are just a tiny sample of the cacti that will be in flower.
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.
Tis the season for prickly pear harvest. Many of our early ripening prickly pears are beginning to change from green to red, providing a lovely feature in the fall garden. Here is our clump of Opuntia pyrocarpa this week. We hope everyone’s prickly pear is growing well from our giant prickly pear pad giveaway at our annual Summer Open Nursery and Garden.
Here are a couple more cactus hybrids flowering in the gardens of JLBG, both created by our volunteer cactus/succulent curator, Vince Schneider. The first is a Trichocereus cross, the parents of which were created by a former volunteer, Mike Papay. Vince crossed two of Mike’s selections to come up with the gem. My camera had trouble since I don’t think this color is supposed to exist in nature.
The second is Vince’s cross of Echinocereus dasycanthus x ctenoides…an amazing blend of colors. We can’t imagine anyone with a dry sun garden that isn’t growing these amazing plants.
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).
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.
Here are some seed and seedpods from the gardens and the greenhouses today.
More interesting seed pods from the garden this week.
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?
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.
