Geranium maderense

Madeira Cranesbill, Cranesbill

Geranium maderense
Price: £3.45
RHS Award of garden meritRHS Perfect for pollinatorsAttractive to pollinators
    Lovely pinky-purple flowers. 4ft (1.2m)

    This is the largest of all Geranium species, a giant aromatic plant with the largest leaves of any species up to 2 ft. across and beautifully divided. It eventually produces an immense inflorescence of countless flowers, each 1½ ins. or so across. Hardy in the milder parts of the country.

    Not to be confused with the greenhouse Geraniums which, as everyone now knows, are Pelargoniums, these are rather fine, hardy perennial plants, many suited to the rockery. Generally, they are shy seeders and seeds are difficult to collect, so we’re afraid they do tend to be quite expensive. Sorry!

    Most seeds germinated, had to pot on fairly quick and all are doing really well.

    Fairly easy to start. 50% germination from two packets. Apparently takes 4 years to full maturity before it flowers. Grew two outdoors in E.Scotland for almost 3 years, but both were killed by several continuous days of sub zero temperature in winter 21-22.Best grown in (big!) pots and sheltered in greenhouse in winter.

    Thank you for your review, we are pleased to hear you have had fairly good germination so far. We don't believe a cold treatment has been given yet and therefore would recommend pricking out the seedlings and then either use the natural winter cold or a fridge to offer a cold treatment, breaking the dormancy of the remaining seeds germination should then occur when given warmth again. The RHS list this plant with a H3 hardiness rating, hardy to -5C. Protection would need to be given if temperatures are below this. Plants should also be mature in 1.5-2 years, being perennial should flower in their second year of growth. We have contacted you directly to discuss further. All the best, The Chiltern Seeds Team

    Germination Instructions

    Sow indoors. Surface sow 2cm apart onto moist well-drained seed compost. Just cover with a fine layer of soil mixed with coarse grit. Keep the soil moist not wet. Ideal temp. 5-14°C. If germination does not occur after 3-4 weeks cold stratify for 2-4 weeks at 4°C, a fridge is ideal. Prick out seedlings carefully as soon as they has 2 true leaves and move to 8cm pots and grow on. Acclimatise and plant out after danger of frost has passed. If you have seeds which have not emerged by autumn you can leave the seed tray outside where winter cold should offer the natural conditions required for germination the following spring.

    Growing Instructions

    Prefers any moderately fertile soil which is moist but well-drained. It will not tolerate a waterlogged soil. Full or part sun.

    Cultivation Instructions

    Remove faded flower stems and old leaves to extend the flowering window and to encourage new leaf growth. Propagate by division in spring.
