Mamm. perezdelarosae

Post by Eric Williams »

Hi all, I have grown this plant for many years now. It looks very well and flowers this time every year without fail. I cannot get it to grow any bigger, or even offset what ever I do. Re potting every few years sees little improvement. May use a different compost this year. Any growing tips and pics of mature plant would be welcome. Thanks

Thanks :) I'm not sure about the taxonomy of these, but yes, it's the version with straight spines rather than hooked.

One of the plants I'm struggling with. For some reason they just keep on dying. Next one I acquire will get grafted ASAP...

Ssp. perezdelarosae in February.

Still flowering today

This subspecies has hooked spines and is quite large, tall even. I find it vigorous. Ssp. andersoniae has straight spines, is smaller, and has more of a tendency to clump.

Not flowering yet this year, but here it is in May last year, so these are completely adult plants.

I can't point to anything special that I do to grow these. As much light as possible to keep them compact and attractive. Ssp. perezdelarosae in particular will stretch with generous treatment in low light.

Thanks all. Some exellent looking plants being grown here. Strange how younger plants look better than others some time. The last pic by lhmbb is comparable to mine which is about the same age. I have to be more patient lol. Cheers

Here is my

16 year old plant without even one offset yet. It's started to lean as per above plant. Could be a sign of an offset lol. Cheers

Mine took a lot of abuse this winter. Soaked, tangled in shade cloth and on the ground in the rain for a month (while I was wondering where it had disappeared to). It decided to forgo flowers but otherwise none the worse for wear.

It's probably about 10 years old now, and has been leaning at an ever increasing angle over the past few years. It's close to 45 degrees now, so it may be time for a repot.
