    Hello sarah

    Not a plant found often in UK gardens . There used to be a small private nursery called 'Fairly Unusual Plants' ***near us in E.Lincs who grew the 'common' pink form from seed . His plants were on dryish , free draining sunny slopes relying totally on the rainfall ; (no artificial watering) . They were lifted and overwintered in a frost free g/house for the winter months

    Apparently quite easy though not tried it myself .

    Can take between 3-5 years to reach flowering size , then die because they're monocarpic . Seeds (eventually) must be saved to propagate the next generation , but are produced liberally .

    *** owner died several years ago !

    I have grown them here on the Isle of Wight. I started them off in an unheated greenhouse and they were easy. However, my soil is very heavy so I wasn't always able to get them through to maturity. They tolerate dry conditions and grow and self seed in a big scree bed in the local botanic garden.

  • We have mature pink floweredimage Geranium maderense growing in our garden.  They appear all over the garden and in the gravel paths too. I usually let one or two grow to maturity.

  • Thank you. I'll have a go and report back!

  • Geranium Madrense Alba, in my experience, will germinate easily if soaked in hot water overnight (not boiling) Drain water off, air dry seeds and sprinkle in a seedling tray in cool spring conditions about 12-16 C. To gather seeds -Cut flower heads off the plant into a paper kleensak, put it out on a hot iron roof or similar and listen to the seeds pop and dry. Add fine scoria/gravel when planting out
