Beautiful flowers Hywel ,I can see how you have made them your hobby :o)

Thank you both :o)

What lovely Lime Green flowers Hywel :o)

I agree its lovely - it seems a more unusual cactus Hywel?

Thank you all

Yes, green is an unusual colour for a cactus flower.
I also have another species with green flowers, but it hasn't bloomed this year :o(

Lovely flower and colour Hywel but its name is such a mouthful to get your tongue around lol

It's like a tongue twister isn't it ... lol :D

Lovely. I don't even try to remember the names of cacti, I just enjoy your pics.

Thank you. I've got so many that I can't remember them all ... so I have them written down :o)
