Gardeners' Notes:


On Jan 24, 2014, coriaceous from ROSLINDALE, MA wrote:

One of the best groundcovers for dry shade. Smothers weeds but isn't aggressive. Tough and reliable. Easy to control.

In this cultivar, the petal color is a soft pastel pink, much softer than the species, which is nearer magenta.

The leaves are fragrant when rubbed or crushed---the fragrance is sweet and pine-like, though a few people find it a little medicinal---bigroot geranium was once the commercial source for oil of geranium.

The thick stems are hardy and do not die down the the ground in winter here (Z6a). They aren't especially attractive in winter, and the plant will come back from the root if you cut them down, but I'd plant this where its winter appearance doesn't matter. Do not rake over it during cleanups.

Beautiful plant. However, for me it's a negative since I am a native plant gardener and Geranium macrorrhizum is native to the South east Alps and the Balkans. If you live in the U.S. and are looking for a native ground cover, try wild ginger instead. It is deer resistant and even repels garlic mustard! http://www.prairienursery.com/store/product_plant_info_asaru...

This is a very useful ground cover that I planted on a shady, dry, steep slope. It's very attractive and low maintenance. Also, it's easy to just pull off a few pieces and start another clump or share with friends. The foliage has a wonderful spicy scent.

The macrorrhizum geranium family is high on my list of favorite plants. They spread nicely without being invasive, They make wonderful ground covers since they can be grown even in dry shade..
The numerous, delicately beautiful blossoms are held high above the foliage in June.
The aromatic foliage is a big bonus to a near perfect plant.

This plant is distinct from the type in having paler pink flowers. The leaves are bronzer in colour and are held much later. They colour much better in the autumn too.
It has the same easy going nature and is useful to smother weeds in dry shade
