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.
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).
