Echinobivia 'Rainbow Bursts'

Highlights

Echinobivia 'Rainbow Bursts': An intergeneric hybrid of Echinopsis x Lobivia. This stunner of a cultivar is lined with ridges dotted with white spines. It produces piles of new offsets around its base which clump up nicely. It gets its name from the explosion of giant pink flowers that bloom each spring or summer.

This cactus variety will not survive a hard frost, but if there is a risk of temperatures below 40F, it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again.

This plant doesn't do that. It just blooms either white or yellow.

The variegated version of this plant can look like that but we only have the plain version. See full answer »

Should the Portulaca molokiniensis lean as it grows? See answer

One of mine is about 7" tall and leaning something fierce. I rotated it to keep the leaning side away from the sun, but it doesn't right itself to lean back towards the sun.

I have it in Bonsai Jack's Gritty Mix, and I water it maybe one a week or so. It sits directly in a south-facing window, no obstructions outside the window either. There's new growth at the top of the leaning stem. There is also some new growth at the base of the leaning stem. See more »

Some leaning and sprawling can happen on healthy, mature specimens as they branch, as seen in the picture at the bottom of this Llifle entry. But leaning can also happen when it's not getting enough sun and it stretches. If you bought it from us, we're happy to take a look at it and tell you which it is.

I’ve had this plant since Dec 2021 and it is growing well but I have had no success with blooms? See answer

Portulaca molokiniensis is a fussy bloomer and it may need care beyond it's normal needs to get it to do so.

Be sure the plant is getting full sun. This is, at least, six hours of light. It will not bloom without that condition being met.

If it is getting full sun and it's still not blooming, try a fertilizer. Be sure to use a fertilizer designed for succulents, or use a balanced fertilizer diluted to 1/2 or 1/4 strength. See full answer »

There is some variation with the bloom color. The most common flower color is yellow, but it can be white too. Then, even among the yellow blooming plants, there is variation in the shade of yellow. In all likelihood, the P. molokiniensis plants we sell have yellow blooms. See full answer »

I believe I got this as a 'mystery" however, the leaves turn white and fall off. See answer

Also, it has new growth coming out from what I think is the roots but they are growing, just dormant. What can I do or not do to help this plant along? See more »

The lower leaves of this plant naturally turn white and fall off. This happens to help preserve energy for the upper leaves, which get more light. The new growths around the base of the plant are likely offsets and they're kept dormant by, what's called, apical dominance. Apical dominance occurs when the tip of the plant uses hormones to suppress branching. Slowly increasing the amount of light your plant receives may help break apical dominance. Cutting the tip of the plant off will surely encourage branching, but it may not look good either. It will be a matter of personal preference.

Please note, you can always email us (info@mountaincrestgardens.com) clear pictures of your plant and we can give you more specified care tips and diagnose problems. See full answer »

Ideally, it should be in an unobstructed south facing window. However, an east or west facing window will work as well. See full answer »

Shop Succulent Soil Here

Succulents need grittier soil than other plants because they are adapted to dry conditions and store water in their leaves. Regular potting soil mixes stay damp for long periods of time, which can cause rot in succulents. Instead, use a sandy, well-draining soil so you can water thoroughly without leaving your succulent in standing water.
