Great plant. I bought a medium sized plant 2 years ago, it grows outside in Sochi, Russia(9B zone). In winter I protect it from rains just with a cover, it's not harmed with light frosts. Must have plant in my opinion.

Friends gave us a cactus planter when my dad died in 1992. I still have this and two of the other cacti in pots. I gave this very little attention, so it is only about 8" across here in 2013, but it did start blooming several years ago in my little greenhouse. The ruddy buds are just now poking up. There have not yet been any pups. How shallow can the pot be?

I love you too, Golden Barrel!
I have a medium sized potted specimen in the standard golden variety, have just sprung for a brevispinus version (pricey but even MORE awesome?) and am looking now for the white one which is also a great big bouncy prickly ball of amazingness. So uncomplaining, so handsome, and more beautiful with every passing year.

If you don't already have one, buy one today, because you don't know what you're missing. That whistling hole in your spiritual plane- it's the lack of a Golden Barrel. Trust me.

Cultivation- there isn't really any. Stick it in a decent pot with a good hole and give it some drainage. Don't freeze it solid, though it's apparently pretty hardy especially when dry. Don't fry it by taking it outdoors in th... read more

Echinocactus grusonii has done extremely well for me. I live in Kentucky where it is humid most of the year -- especially in
the summer. I purchased a good-sized plant sometime in the
early 1960's and it is still living! It has bloomed for the past 6
or 7 years -- all summer long! I just can't figure out how to go about removing it from it's Italian clay pot to put it in a larger
pot. I really don't want to break the pot and the spines are

In a succulent, or xeriscape landscape, combine Golden Barrel cacti with Agave paryyi var. truncata. This is a beautiful combination of bright yellow and very pretty blue. They compliment each other well. Good luck!

This plant is a of Queretaro de Arteaga, Mexico. I like the yellow color and wish I could get more of them to grow in this greenhouse.

I have planted over 20 of these of various sizes and they are doing well. They have survived a freeze down to 19 degrees. They do a little better with some shade, especially when young. I find the color really brightens up a xeriscape garden.

bought one with three pups 5 yrs. ago. it now has 3 more pups form the 'mom' and a pup one of the original pups. no flowers yet. this early spring we had over an inch of rain (wow). all the larger apple and cow's tongue are blooming profusely ( what a beautiful sight.

This plant dosen't have herbaceous stems nor does it have any foliage (leaves). If the plant has multiple stems, the offsets can be carefully separated and rooted. Propagation also by seed.

I have always loved Barrel Cactus.. Although i have never owned one, until now!! I went to Albertsons today, and i was just checking out what little plants they have, and i couldnt believe it when i saw that they had Barrel Cactus.. They all were in 8" pots, and they were only 1 dollar!?!?!?! Can u believe that! So i got two! I asked the manager how long they have been there, and he said over 2 weeks, and no one has bought any. So i was the first to buy two! They have a lot, but i just wanted two, my yard is kinda crowded right now.. I just fertalized them, and i know they will get nice and big for me, I love you Barrel Cactus!

LOOKING FOR IMPACT? This is the one that gives a huge dose of impact. The striking round shape and the dramatic golden color are unique. Inch for inch this is the most dramatic landscape plant you can buy. It is an eye catcher without equal. This is a bread-and-butter plant for any landscape display. Unlike many plants, golden barrels get more and more beautiful as they grow. As old specimens they can be truly majestic. They normally offset with advanced age and a few multiples occur even at small sizes. Barrels are quite heavy.

Although this plant seems to be doing well in my Tampa back yard I'm not sure if I should move it. It appears that it might be getting too much water --needs more drainage.

It is also partially shaded.

Other than that (check my pics) it fairs well. It was here when I moved in (September 03) so I'm not sure how long the previous owner had it, she planted it but she had only lived here 2 years previously.

I've never seen it flower, but that might be that it needs more sun.

I have a very small "baby" plant I bought at one of our local nurseries in August. I have been told it is a slow grower. I can't wait until it gets the size of the others pictured, but for right now it's an adorable baby!!
