About Philippe Vapelle Cranesbill

Geranium 'Philippe Vapelle' · also called Philippe Vapelle Cranesbill, Philippe Vapelle Geranium · flowering

Geranium 'Philippe Vapelle' is a hybrid of G. renardii and G. platypetalum raised by Alan Bremner at Axletree Nursery in Scotland, forming a neat clump of attractive blue-grey, softly hairy, finely wrinkled lobed leaves. Blue-violet flowers with strongly dark-veined petals open in summer above the textured foliage. The single most important care fact is to provide a sunny, well-drained position — the renardii parent demands good drainage and dislikes poorly drained winter soils. The ASPCA 'Geranium' toxic listing refers to Pelargonium, not true cranesbills; true Geranium is not individually confirmed non-toxic, so treat with caution around pets.
