Plant ID please

Bought yesterday at a local garden centre .... because it had flower buds.
An identification please.

Mammillaria elongata which is very variable in flower colour (mostly seen with whitish/yellow flowers) and spine colour.

I have a few that seem to be fairly hardy as well.

Mine are a good age and very hardy. I say are and not is for this reason.

I've only ever had the one pot and get two flower colours.

[Diane]

I would suggest that yours is Mammillaria microhelia, Fred, which can have pink or yellow flowers.

[Tony R]

Agreed. Your pink flowered clone has been known as Mammillaria microheliopsis in the past.

[FredG]

You think it's/ they've had the wrong name for 35+ years?

I knew I should have just called it George

[David Neville]

Yes FredG, I agree that these thicker stemmed relatives of M elongata that you show in your pix are what we used to know as Mamm. microhelia and Mamm. microheliopsis, the differentiation based only on the flower colour in earlier times. This has always been one of my favourite mamms because I first grew it as as schoolboy.

[FredG]

Woo Hoo! I get to print another label

[el48tel]

I was going to print a label, last evening. I'm so glad I waited.

I see that LLIFLE lists several more synonyms
