SYN.

Echinobivia ‘Rainbow Bursts’

Echinopsis Zucc. is a correct and accepted scientific name for the genus. It was named and described as such by Joseph Gerhard Zuccarini in Abhandlungen der Mathematisch (short version) in 1837. Plants of the World Online by Kew currently lists 70 accepted species of Echinopsis (as of when I updated this page on 7-13-19). According to the 2013 version of The Plant List, there were 131 accepted species of Echinopsis (plus another 25 accepted infraspecific names), 627 synonyms (of which 245 were infraspecific names) and a total of 159 unresolved species. Remember, that was in 2013 and The Plant List is no longer maintained.

The synonym, xEchinobiva G.D.Rowley, was named and described as such by Gordon Douglas Rowley in the Cactus and Succulent Journal in 1966.

I bought this Echinobivia ‘Rainbow Bursts’ from Wal-Mart on 2-1-16. The label said: ”Rainbow Bursts are so named for their spectacular display of colorful flowers during the spring and summer. These hybrids are cross (combined genetics) of Echinopsis species and Lobivia species, hence the name Echinobivia. Protect from frost.” The plant was growing in a 2 1/2” (4 oz.) pot. It measured approximately 2 1/4” tall x 3 1/2” wide.

Information online says Echinobivia ‘Rainbow Bursts’ can be white, yellow, gold, orange, pink, red, purple, and sometimes bicolor.

The genus Lobivia Britton & Rose WAS also a correct and accepted scientific name for this genus of cacti. It was named and described by Nathaniel Lord Britton and Joseph Nelson Rose in The Cactaceae in 1922. Most of the species formerly in the Lobivia genus are now in the Echinopsis genus. Some were transfered to other genera and some of those are now species of Echinopsis.

While most of the Lobivia species and infraspecific names have been moved to the Echinopsis genus, a few were transferred to the Rebutia and Acanthocalycium generaCurrently, Plants of the World Online lists 69 accepted species of Echinopsis, 29 species of Rebutia, and 5 species of Acanthocalycium.

Echinopsis ‘Rainbow Bursts’ (Syn. x Echinobivia ‘Rainbow Bursts’) at 2 3/8″ tall x 4″ wide on 10-17-17, #384-5.

I moved the plants inside for the winter on October 17 (2017). The first stop was the basement where they were all photographed and measured. This plant was 2 3/8″ tall x 4″ wide. It didn’t grow much because it was 2 1/4″ tall x 3 1/2″ wide when I brought it home in July 2016.

All those kids can be removed and rooted or they can be left attached. I am opting to leave them attached because I certainly don’t need that many Echinopsis plants and how long would it take them to grow?  I guess that calls for an experiment.

How would you like to sit on that? The top view of most cactus is just as interesting as the side view.

Echinopsis sp. (Syn. xEchinobivia cv. ‘Rainbow Bursts’) on 1-1-18, #401-4.

I put the Echinopsis ‘Rainbow Bursts’ on a table with most of the cactus and succulents in my bedroom for the winter. They received plenty of light from a south facing window.

The Echinopsis ‘Rainbow Bursts’ was happy to get outside for the summer again.

I decided to put this plant and all its kids in a larger pot. It was beginning to bulge. Even though you are supposed to only increase the pot size by 1/2 to 1″ in diameter, I gave this cactus a bigger pot in case the babies fall off and need room to root.

I moved the potted plants to the front and back porches on July 4 (2018) because of a Japanese Beetle invasion. The plant tables were next to and behind a shed under a Chinese Elm tree which the beetles love. The beetles were beginning to sample a few of the other plants so I moved them. I moved most of the cactus to the back porch including the Echinopsis ‘Rainbow Bursts’. You can see the dead leaves from the elm tree in the pot.

I measured the cactus on October 10 when I was getting ready to move the plants inside for the winter. The cluster of Echinopsis ‘Rainbow Bursts’ now measures 3″ tall x 5″ wide. It didn’t grow that much from the time I brought it home in July 2016 until I measured it last October. This time, however, it grew 3/4″ in taller and 1 3/4″ wider.

We had a couple of nice spring-like days the last part of November, so I decided to take the cactus outside for a photo shoot for a new post. The post was for comparing the difference between the cactus I have in my collection.

Here you see the parent Echinopsis ‘Rainbow Bursts’ has very small spines and a little wool on the areoles. The hair you see in the photo is cat fur…

The offsets have more and longer spines in relation to their size than the original plant. The offsets grow between the areoles.

The Echinopsis ‘Rainbow Bursts’ is enjoying another summer on the back porch. The offsets keep getting bigger

There is quite a bit of information online about this genus and many species. It is quite a celebrated due to their ease of keeping and especially their beautiful flowers. I will be glad when it blooms!

I will continue adding more photos and information as time goes by. If you have any comments, questions or suggestions, I would like to hear from you.

    I think that’s great. I have a similar sized rainbow burst. I recently removed the babies from the cactus and sold them. I am hoping that I can get blooms next year. I have found with another echinopsis that I have that they need a good rest period in order to bloom. That includes cool and dry conditions for more than a month.

    • Hello Sclerocactus Daddy! Glad to hear you have a ‘Rainbow Bursts’, too. I have been thinking about removing the babies but I have been saying that for a long time. After all this time it would look kind of bare. Mine is in a cool room during the winter and I don’t water but maybe twice during that time. Still no flowers… I guess it will when it gets ready. Keep me posted and thanks for the comment!
