Rebutia senilis

beautiful colour:-)

Have not had time to look lately but these are are lovely.

Thank you both

Don't worry about it Scotsgran ...

Great closeup. Are they that bright/colourful to attract insect pollinators or just because they grow in bright sunshine?

What a beautiful flower Hywel lovely and bright, great picture you can see the shading in the petals :o)

Thank you all for your comments.

Gee - Cactus flowers only last a few days at the most, and therefore have to be brightly coloured in order to attract pollinating insects, before they wither
:o)

What a lovely colour.

Thanks, Hywel, I like to know why things are what they are :)

Me too, Gee. They are stunning, aren't they.
