This is my oldest cactus and the most reliable bloomer. It flowers from April to September. During its flowering season, this cactus has consistently produced over 120 flowers each year.
Once this cactus started producing flowers in May, it has bloomed once a month since. As summer moves on, the flowers become smaller, but stay the intense orange that you see here. Each round of flowers produces at least a dozen at a time.
'Rose Quartz' flowers several times starting in late spring. The flowers get lighter and lighter with each flowering. I think I like the color of this current flower more than the darker rose of earlier months.
The x before the name signifies that this is a hybrid Echinopsis. This cactus is a cross between the Chamaecereus and Lobivia genera, which are now classified as Echinopsis. Or something like that.
This cactus not only has beautiful flowers, but I think the cactus itself is an especially attractive one. It always produces several flowers at once. Last month it bloomed in May, June, August and October. This year, it flowered in June and July. We'll see what happens later!
The x after the name Echinopsis signifies that this is an Echinopsis hybrid. No crosses with other genera, just crosses with other Echinopis. Or something like that.
