About Geranium pratense 'Mrs Kendall Clark'

Geranium pratense 'Mrs Kendall Clark' · also called Mrs Kendall Clark meadow cranesbill · flowering

'Mrs Kendall Clark' is a refined meadow cranesbill prized for soft greyish-blue petals veined with paler grey-white, opening over deeply cut foliage in early summer.

Mature size: 60-75 cm tall and 45-60 cm wide.

Watch for — Sawfly and vine weevil larvae: Chewed or notched leaves indicate larvae. Pick off or use biocontrols, then cut back for clean regrowth.

Indoor size vs how big it gets in the wild

Geranium pratense 'Mrs Kendall Clark' stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect 60-75 cm tall and 45-60 cm wide.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Geranium pratense 'Mrs Kendall Clark' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: low feeder. a spring mulch of compost or one balanced feed at growth start suffices; skip high-nitrogen feeds, which promote weak, floppy stems over flowers.

Want this turned into the right next pot at the right moment? The pot size calculator and the geranium pratense 'mrs kendall clark' repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast geranium pratense 'mrs kendall clark' grows.

How to keep geranium pratense 'mrs kendall clark' smaller

You are not stuck with the maximum size. For geranium pratense 'mrs kendall clark' specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting geranium pratense 'mrs kendall clark' is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide geranium pratense 'mrs kendall clark' out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow geranium pratense 'mrs kendall clark' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for geranium pratense 'mrs kendall clark' the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The geranium pratense 'mrs kendall clark' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When geranium pratense 'mrs kendall clark' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for geranium pratense 'mrs kendall clark':

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the geranium pratense 'mrs kendall clark' repotting guide. If you want more of this plant instead of a bigger one, the geranium pratense 'mrs kendall clark' propagation guide turns prunings into new plants.
