Banned Down Under


Opuntia paraguayensis


This is the first flowering for my small Paraguay Cactus. I was expecting orange flowers, but not surprisingly...more yellow. Sometimes I think that there's something about my garden that causes so many cacti I have to unexpectedly produce yellow flowers! These blooms are late--most all my other Prickly Pear species bloomed a couple of months ago.


This species of Prickly Pear is banned in Australia because it can become quite invasive. Compared to other Prickly Pear species I have, this one is very slow growing, so I don't think I'll have any problems in that regard.

Oh, so very banned... However, somebody down my street has one in their front yard, and yesterday in the garden shop they had several for sale!

Very nice shot! I love the little buds- hard to imagine it as threatening anywhere!

Angie said...

What a lovely bloom! Your cacti all look so amazing! You definitely have a green thumb when it comes to them!

Funny how something so harmless looking can be invasive!

Maybe it's the soil pH. or something about the mineral content that makes your blooms go yellow.

Like Hydrangea that blooms blue in acidic soil but white in alkaline.

Send me one - my winters will take the invasive nature out of it and make it go into permanent dormancy. If that doesn't work I'll have my wife take care of it :)

Lovely flower on such a prickly plant

Lovely blooms again, Aiyanna. i think the buds are almost as pretty as the open flower.

More iron should cause more blooms to come in orange.

Lovely blooms. I enjoy cactus flowers and their buds too.

I was thinking that it might be the ph of your soil or too much or a lack of one mineral or another that tends to make your flowers all bloom yellow. Perhaps you could have your soil tested? Either way, yellow flowers are pretty.

That's a lovely flower. So delicate compared to its cousin prickly pear.
and the multiple buds are lovely, too.

Great shot! Can a cactus have two different colors on the same plant or only one?

Julie said...

Love those L-O-N-G spines! LOL. Pretty flower even though yellow. Do you have any opuntia that are thornless? I can't remember...if you do...you could really have some easy good eatin! LOL.

What a cute little cactus. And I'm sure the yellow flowers were a sweet surprise!

Claude said...

It seems that you can always count on prickly pears to perform, even if they don't want to bloom the proper color! But I would try the iron in the soil that's been suggested. Can't hurt.

I dug around my garden supplies and found some chelated iron, so when the weather cools, I'll add some to the soil around some of
the cacti that have yellow flowers (at least the ones with out-of-character yellow flowers)and see what happens next year. This should be an interesting experiment!
Thanks for all your GTS comments this week.

KML,
I've seen cacti with different shades of the same color, but not two different colors--at least not in the same bloom season. Many cacti that bloom several times a season have flowers that generally fade in intensity from first bloom period to last. Also, I have a Gymnocalycium that has flowers that are more pink one year, and then more salmon the next.

Still a nice color. Thanks for sharing the pic.
