____________________________________

Geranium macrorrhizum is a medium-sized hardy Geranium useful for evergreen ground cover and in shady spots. It has sticky, lobed leaves, smelling strongly of ripe plums (or ripe Passion Fruit), which turn red in autumn. It spreads by rhizomes to form large colonies. In early summer, it bears small clusters of flat flowers in shades of pink or white, with protruding red stamens and inflated red calyces. The photograph is Geranium macrorrhizum 'Ingwersen's Variety'.

Harvesting and Growing from Seed:

Seed Pod
The seed pod is a thin woody case which stays on the seeds. The seeds are in the middle of the red calyx, which opens when the seeds are ripe.

Seed
The seeds are small pale brown pointed ovals. Each flower has five seeds in a ring at the bottom of the style.

Seedling
The seedleaves are rounded with a notch, with a long reddish stem. The first true leaves are trifoliate.

Seed sowing and Germination
Summer: Seeds sown inside in summer germinated in 3 days.
Winter: Seeds sown between folded paper towels kept inside in winter germinated in 71 days.
Geranium seeds may germinate faster if they are nicked slightly before sowing.
