About Geranium maculatum

Geranium maculatum · also called Spotted cranesbill, Wild geranium · flowering

Spotted cranesbill is a North American woodland perennial bearing loose clusters of pink to lilac-mauve, five-petalled flowers from mid-spring into early summer above palmate, lobed leaves. A reliable shade-tolerant native that supports early pollinators, it forms gradually expanding clumps, prefers moist humus-rich soil and dies back to the ground each winter.

Plant type: flowering

Watch for — Floppy, shy flowering in deep shade: Stretched, lax stems and sparse blooms where light is too low. Move to part shade or dappled light for sturdier, free-flowering growth.

The reasons geranium maculatum isn't blooming

Almost every non-blooming geranium maculatum traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding geranium maculatum a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get geranium maculatum to flower

Maximise sun. Give geranium maculatum the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for geranium maculatum and get the feeding right with the geranium maculatum fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Geranium maculatum flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full geranium maculatum care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Geranium maculatum blooming — frequently asked questions

Why won't my geranium maculatum flower?

Geranium maculatum blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make geranium maculatum bloom?

Give geranium maculatum the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
