About Alpine Cinquefoil

Potentilla crantzii · also called Alpine Cinquefoil, Crantz's Cinquefoil · flowering

Potentilla crantzii is a neat, clump-forming alpine cinquefoil found across the mountains of Europe and western Asia, bearing cheerful golden-yellow flowers with a distinctive orange basal spot on each petal from late spring to midsummer. It is highly adaptable, thriving in rocky grassland, scree, and cliff habitats — a reliable, low-maintenance plant for rock gardens and alpine troughs.

Mature size: 10–25 cm tall in flower, 20–40 cm wide

Watch for — Sparse flowering: Insufficient sun is the most common cause. P. crantzii flowers best in an open, sunny position. Also check that the plant is not rootbound in a container (repot in spring) or grown in overly rich soil, which promotes foliage over flowers.

How to tell alpine cinquefoil needs repotting

Repotting on a calendar is less reliable than reading the plant. For alpine cinquefoil, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot alpine cinquefoil

Every 2–3 years, into bone-dry mix. Alpine Cinquefoil's growth habit — clump-forming to loosely mat-forming, semi-evergreen perennial — sets the pace. Potentilla crantzii is a neat, clump-forming alpine cinquefoil found across the mountains of Europe and western Asia, bearing cheerful golden-yellow flowers with a distinctive orange basal spot on each petal from late spring to midsummer. It is highly adaptable, thriving in rocky grassland, scree, and cliff habitats — a reliable, low-maintenance plant for rock gardens and alpine troughs.

What size pot to step alpine cinquefoil up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Alpine Cinquefoil stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot alpine cinquefoil

Spring or summer, while alpine cinquefoil is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting alpine cinquefoil

Repot dry. Do not water alpine cinquefoil for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty well-drained, lean, neutral to slightly alkaline stony or gritty soil ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set alpine cinquefoil at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep alpine cinquefoil completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for alpine cinquefoil

Alpine Cinquefoil wants well-drained, lean, neutral to slightly alkaline stony or gritty soil. Adaptable to a range of well-drained soils (pH 6.0–7.5). Grows naturally on limestone, sandstone, and schist. A 50:50 mix of loam and coarse grit works well in containers and raised beds. Avoid heavy, fertile soils that retain moisture — lean conditions keep the plant compact and healthy. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting alpine cinquefoil — frequently asked questions

How often should you repot alpine cinquefoil?

Every 2–3 years, into bone-dry mix for alpine cinquefoil. Repot alpine cinquefoil every 2–3 years into a snug pot of well-drained, lean, neutral to slightly alkaline stony or gritty soil, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does alpine cinquefoil need?

When is the best time of year to repot alpine cinquefoil?

Should you water alpine cinquefoil after repotting?

No — not straight away. Repot alpine cinquefoil into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise alpine cinquefoil after repotting?

Not immediately. Wait about 3 weeks after repotting alpine cinquefoil. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
