Geranium maderense I'd say

Thank you.

Interesting. Appears to be either a perennial or a biennial, depending on where you look.

G. maderense is monocarpic - it many take years to bloom, but then dies.

Mine self seed with abandon, especially in pots and paving, and never look as miserable as the ones in the pictures. Because there are always many coming along I've never really registered how many years they take to bloom. I sort of assumed they were behaving as biennials. Even not flowering the foliage is attractive.

It is a biennial so only tertiarily considered monocarpic. And will bloom reliably its second year in an appropriate climate.
