Gymnocalycium mihanovichii var. friedrichii a.k.a. the Ruby Ball, Rose Plaid, or Moon Cactus

Hi there! As promised, I'm back with a garden post...

From the research that I've done, this beautiful little cactus is called Gymnocalycium mihanovichii var. friedrichii, a.k.a. Ruby Ball, Moon Cactus, or Rose Plaid Cactus. Personally, I like Ruby Ball the best!  If I'm wrong about this name and anyone out there knows differently, please let me know in the comment section. Apparently, its close family member is Gymnocalycium mihanovichii var. hibotan, which is the same cactus that took my breath away while browsing the famous Amsterdam Flower Market - check it out in this post!

I first bought this little guy back in April of 2010, when I was living in Downtown Miami, seen here and here.  Since then, I've planted it in a big round terra-cotta bowl planter and it's doing great so far.  Although, this cactus did go through many months of looking shriveled and dark green (when I had her in my to-be-planted cactus pileup), but after some sun and water she got her groove, err succulence, and color back...  Nowadays, she puts out some amazing little pinkish purple flowers throughout the year, seemingly nonstop!

Miss Mihanovichii Friedrichii, as she is now called, is about the size of a lime and can range in color, from dark green, to brown, to dark purplish fushchia, to the beautiful mauve pink color shown in this post.  For me, it has grown better in bright direct sun with afternoon shade, rather than just shade alone.  I usually let mother nature water it naturally, unless we have many hot sunny days and I see the soil around it is hard and dry.  Every now and then I will fertilize it with Schultz 2-7-7 Cactus Plus Liquid Plant Food but sources say to fertilize every two months (see below for more information).

Okay, no more rambling, scroll on to see progress photos from when the two flower buds first sprouted, to when they eventually bloomed a week or two later! Nature rocks...

This is the terra-cotta planter bowl that I planted Miss Friedrichii in, I bought it at Home Depot.  I always buy my planters at TJMaxx, Ross, and Marshalls because they are so affordable, and Home Depot is way overpriced in the planter department, but this time I made an exception because it was only $9!

So this is what my Ruby Ball Cactus looked like when I finally got around to planting it in something bigger, back in February of this year...
 

The sweet delicate flower stems sprout right from the top center of the cactus...

Here is how she looked in March...

Up close and personal...

Just on the verge of blooming...

And then, in April, BAM!!!....

There they are!  Gorgeous huh?  :)





So basically, here is how it progressed over three months...





Here are some shots of the other succulents and cacti in the planter, I can't locate their names in my notes at the moment... oops...
