This plant is a workhorse for me!

I have it planted on the north side of the house, in deep shade, quite dry in the summer. It's lush, bright green, lovely ground cover - and evergreen in this spot - amazing for Colorado.

I have more growing against a southwest-facing concrete wall. It blooms best here, though by the end of summer, the leaves are crispy on the edges. It recovers and looks great through fall and vanishes in winter.

I have some also beneath aspen trees in dappled sun and quite dry. They bloom pretty well and the bright-green, fuzzy foliage looks fresh all season.

Try planting "Tiny Monster" behind macrorrhizum. The leaves contrast so well!

Lovely plant habit and flowers in spring.

I had difficulty getting just the right situation - with not enough sun it blooms much less, and with too much - esp afternoon - the leaves wilt every day. I now have it where it gets morning sun and filtered afternoon sun - perfect!

Ive had this particular geranium for about five years. I love it! It is in partial sun and has formed a mound that is about a foot high. Requires no special care. It has small magenta flowers in the spring.

In the Dallas/Ft. Worth area, this plant is evergreen, surviving temperatures below freezing. I have it in part shade and does very well, blooming in the spring. It might bloom more often in more sun, but it likes it where it is with very little supplemental watering. It is hard to find though.

A very nice plant.... easy in part sun and shade.... recommended! :)

Very hardy and low maintenance. Bright pink flowers in mid-Spring. I divided mine before putting them in the ground and they've tripled in size in just a couple of years. Loves their sunny location.

Oh... and my dogs HATE the smell. The rabbits have been leaving them alone too.
