Description –
Geranium maculatum is a herbaceous perennial that grows up to 60cm tall, producing erect stems and flowers, usually unbranched in spring to early summer.
The rhizome is 5 to 10 cm long and thick, with numerous branches. It is covered with scars, showing the remains of the growth stems from previous years. Once dry, it has a purplish color internally.
The leaves are palmate and lobed in shape with five or seven deeply incised lobes, each of which is again split and toothed and are 10-12.5 cm wide, with a petiole up to 30 cm long.
The flowers are 2.5–4 cm in diameter, with five pink-purple, pale or purple-violet (rarely white) petals and ten stamens. They are grouped in loose corymbs or two to five umbels at the top of the flower stems.
Flowering can go from April to June, depending on the latitude.
The fruit is a capsule that opens when ripe, and is composed of five cells each containing a seed joined to a 2-3 cm long beaked column (similar to the beak of a crane) produced from the center of the old flower.

Cultivation –

This plant grows in any soil, as long as it is moderately fertile and in a sunny position.
