Spring flower review, Part 3

Post by Steve Johnson »

In this installment of my spring flower review, we'll look at...

A pair of Gymnos and Sulcos

Gymnocalycium ochoterenae vatteri -- a 2011 veteran, and so reliable about blooming from spring all the way through early fall. First bud of the year on May 4, then 3 weeks later and well underway with another bud in tow:

Image

A flower on Memorial Day:

Image

Here's another Gymno, and that would be my stenopleurum. One of the points of interest about this plant is the fact that it'll start setting buds late in the year. And talk about reliable! So far those late-season buds have never failed to winter over, then go into flower the following spring. Doing it for a 2nd winter season in December:

Image

On the 1st of February, after the buds started slowly waking up in the new year (I'm sure the unusual winter heat helped):

Image

Wow, it didn't take long for bud #1 to pop -- on 2/15...

Image

...then in bloom a day later:

Image

Okay, not the best effort, so let's try again. That's bud #2 finally doing something on May 4:

Image

A very pretty bud it is, too -- on the morning of bloomage, 5/14:

Image

For some reason, those stenopleurum flowers are shy about opening in spring. Here's the difference between day 1 and day 3:

Image

Image

Truth be told, the vatteri and the stenopleurum both need a lot of heat to get their flowers wide open. August is historically the hottest month of the year here in L.A., so I'll expect to give you a proper display then. I do have a Gymno that wasn't shy about its first flower of the year at the beginning of June, but I'll leave it for Part 4. In the meantime, the stenopleurum's latest flower didn't do much after it opened about 2 weeks ago, but it sure is pretty on the way out:

Image

Next, we'll check in on my Sulcorebutia rauschii. Another one of the veteran cacti when I started the current collection in 2011, and a real success story after I turned it around with a few life-saving changes to my overall growing approach. The rauschii gave me its first-ever flower in July 2012 -- an amazingly pleasant surprise which told me the plant was on its way to recovery. Then a year ago it flowered again. Now here's what the rauschii did this spring. First buds detected at the end of April:

Image

Getting a little bigger on 5/17:

Image

Even bigger on the 21st:

Image

Now it's showtime -- what a lovely Memorial Day weekend that was!

Image

Image

Not prolific by any means, but those vivid, colorful flowers are always welcomed on the plant bench. I'm familiar with the rauschii's behavior, so here's the sequence of events -- after the flowers come new pups. Yep, I have a couple of those to go with the 9 that came in over the summer of 2012. Unfortunately I didn't see any offsetting last year, which I'll blame on the oddly cool funk of the "summer that wasn't" (uh oh, there we go again. :roll: ). Prospects for a nice hot summer are looking favorable this year, so you can bet your bippy that I'm on the lookout for even more pups to increase my lovely rauschii's brood. Now, if it's prolific Sulco blooms you want, I can oblige...

Enter Sulcorebutia aranacea courtesy of CoronaCactus, joining the collection last July. I detected its very first buds way back in January:

Image

More buds kept coming in, then the blooming started in early March. In fact there were so many flowers this spring, I couldn't keep up with all of them, so here are just a few highlights. On March 8 as the flower derby begins:

Image

Image

I thought I saw what could've been my first crested flower when I showed you the Sulco callichroma longispina in Part 2. But after reviewing the aranacea pics in my archive, I believe the honors go to this one:

Image

Still March here, on 3/16 with various stages of budding and flowering:

Image

A nice flush going on 3/23:

Image

Image

Here's a beautiful singleton, all wide open and out in the sun on 4/12:

Image

Another singleton with a crop of new buds -- and you'll see only a few of them in this pic!

Image

We'll fast-forward to June and the last big flush on 6/5:

Image

As we speak I'm viewing a couple of holdout flowers, but that'll be pretty much it for the year. That's what I call a fabulous showing for my lovely "monster" Sulco!

After everything you've already seen thus far, I'm saving the best for last. Be sure to keep your eyes peeled for the 4th and final part of the spring flower review!

I think my G. vatteri popped its first flower on the same day. Certainly the same week. It has more of a red eye though. I was surprised that I couldn't find a photo, but here it is two years ago, middle back.

Do you grow your G. stenopleurum in the shade? They fry in full sun here, and some of its relatives look toasted even in the shade:

Your Gymnos produce such lovely blooms -- certainly better than mine, although my baldianum makes up for the rather drab flower colors I see on the vatteri.

Yes, I keep the stenopleurum in a place called, oddly enough -- Shady Glen. You can see it here toward the upper right-hand corner:

Image

Well, maybe not that shady, since the south-facing side of the plant is in constant sun over late spring and summer. Of course, I rarely look at that side. Using the "poor man's light diffuser" here to get rid of the high contrast between full sunlight and shadow, I think you can tell which side is which:

Image

Whenever I talk about full sun in my setup, I should include the caveat that I've been keeping the entire collection under a 40% shade cloth enclosure since I started it 3 years ago. I'm sure this helps, and without the shade cloth I'm equally sure that the stenopleurum's south-facing side would get toasted -- especially over the hottest days of summer. An interesting little note on watering while we're at it...

My vatteri gets watered every 2 weeks in spring and summer, staying nice and plump pretty much all the time until it shrivels a bit in winter. On the other hand, I do think the stenopleurum may have that thirsty look which tells me it isn't getting watered often enough. Such being the case, I'll have to seriously consider weekly watering for the plant so it plumps up more. This Gymno has been with me for 2 years, so it's entirely possible that I've been holding the stenopleurum back from producing the amount of new growth it should in summertime. Feedback, anyone? :-k

G. stenopleurum always looks thirsty, but mostly it just has very sharp ribs.

I took a new photo of G. vatteri since it was flowering today. Still quite flat. I water regularly, but probably one day I'll repot and fine there is no soil in the pot, just roots and a few stones. No shade for this one, except on the very hottest days because it is possible to scorch it.
