Echinocereus rigidissimus ssp. rubrispinus

Post by Diane »

I think this has to be my favourite Echinocereus, having wonderful red pectinate spines and such beautiful bicoloured flowers.

That’s a beaut! Definitely my favourite flower of Echinocereus as well. I have a smaller plant with just one bud forming at present. Waiting patiently for it open :grin:

A very nice clearly defined eye to the flower. Well grown.

Although we live miles apart, mine also flowered this morning! I took a picture just as it was opening, and it hardly looks real:

Isn't it amazing, Ralph? I have two more, one also started to open today, but the smallest one only has a small bud at the moment.

Mine is still in bud. I wonder how big the plant can get, mine is now very tall (about 25 years old now), has never branched and still going slowly upwards

That is indeed beautiful Diane.

Mine appears to be behaving a little oddly... Since I've had it, it has always maintained a compact, regular form (though has yet to flower for me). For the last few weeks, the spines near the top of the plant have been "spreading", revealing the bright green skin underneath. Is this a known phenomena? Or is there something wrong?...

I need to know the answer to that question because mine has developed similarly but not quite to the same extent.
Is it building two more ribs?

It looks as though it's split - possibly after watering? Definitely not new ribs forming.

My white- flowered form of this species has now opened ( a bit difficult to take a good picture in strong sunlight!)
