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.
Preferred mix: Moderately fertile, well-drained
Watch for — Vine weevil: Notched leaf margins indicate adult feeding; creamy-white grubs in the root zone cause sudden wilting; apply Steinernema kraussei nematodes to moist soil in late summer to early autumn.
Why philippe vapelle cranesbill needs this mix
Philippe Vapelle Cranesbill flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for philippe vapelle cranesbill: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons philippe vapelle cranesbill struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives philippe vapelle cranesbill weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving philippe vapelle cranesbill in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for philippe vapelle cranesbill?
Most flowering plants, including philippe vapelle cranesbill, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for philippe vapelle cranesbill in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for philippe vapelle cranesbill covers the timing and technique step by step.
