Both of these cacti have open flowers today. On top, open in the back patio area, is a local native mammillaria sheldonii fishhook cactus we rescued from a construction area down the road a year or two ago. Below, open in the courtyard out front is a mammillaria yaquensis fishhook cactus that was a gift from our friend Crotalus.

Update: Crotalus advises us that the top panel specimen might actually be mammillaria tetrancistra. The one we quoted above typically is found only in Mexico.

The Wikipedia Page for generic Lantana enumerates about 150 species for the genus of these shrubs. I’m not going to begin to venture a guess as to which one is depicted in the image.

We were at the Community Hospital clinic today to see one of the specialists and this nice flowering bush was along the sidewalk leading into the facility. I took this close-up of a couple of florets on the bush. In this image you can see how the more mature flowers in the cluster turn orange and yellow with age:

Lantana’s aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored.

The first of this season’s gorgeous Pride of Barbados (a.k.a. Red Bird of Paradise) flowers have opened. This is about a week earlier than in previous years. It seems that as the shrubs mature, they get their flowers earlier.

All three of the Red Bird shrubs have flower pods; the one shown above is on the westernmost of the three and is the only one with pods open today. This past winter we cut the shrubs to the ground as usual, but shortly after that and very early in late winter, the foliage reappeared.

There are lots of flower pods out there and I expect to have a lot of these colorful flowers opening all summer. Click on the image to enlarge.

Our Trichocereus “Cherry Red” Cactus is fully in bloom this weekend. This is the second year we have had this cactus in its pot on the courtyard patio.

From Tucson Cactus and Succulents:

Trichocereus hybrids grow well in large pots or in the ground in the desert Southwest. Some growers can adapt them to full sun, but to avoid sunburn it’s safer to grow them in light shade, as under an unirrigated mesquite or palo verde tree. They respond dramatically to generous water and fertilizer. With weekly watering and monthly feeding, the best cultivars will flush massive blooms every two weeks or so for three months or even longer. With water restriction, bloom will be much reduced in number. (Some clones will flower for only one or two days a year; there is a great deal of genetic as well as cultural variability.) The authors obtain superb results using a water soluble ‘Bloom’ formula fertilizer, one with low nitrogen and high phosphate. Deadheading (cutting off the spent blooms) close to the stem will result in greater flowering potential since the plants may often abort new flower buds in favor of producing fruit from pollinated flowers. Trichocereus flowers may be enjoyed as cut flowers indoors in water.

If you live in the desert, you’ll need to protect your trichos from javelinas, rabbits, squirrels, or even deer; they will eat your flowers. Additionally, insect pests may include, the giant cactus beetle, Moneilema gigas, the cactus weevil, Cactophagus species, thrips, and cactus moth (blue cactus borer), Cactobrosis fernaldialis. These can easily be treated with regular applications of systemic insecticides.

Four of the flower buds on the Astrophytum “Star” Cactus in the courtyard opened up today. These are the first flowers on this barrel cactus since last year in early June. Click on the image to enlarge.

After getting home from our recent vacation from retirement ( 😆 ), we haven’t been doing too much other than just getting back into our normal at home routine. We have some disruptions pending that include taking the new motorhome to the dealer to fix warranty squawks and an appointment with Bob’s urologist for more bladder biopsy stuff, all of which will be this month. June should see us back to our summer routine here in the desert.
