Gardeners' Notes:


On Sep 2, 2015, ridoodles from Warwick, RI (Zone 6b) wrote:

Mine were purchased at a nearby farm about 7 years ago. If you like a ground cover that keeps on giving from Spring until summer w pink blooms you will love these. Mine thrive in filtered light under large bushes, in RI by seacoast in rocky gravel. Never water never fertilize and returns each year w a few new babies by her side. Easy to care for , just simply ignore. I would like to start some from seed, does anyone have experience.

Yes, it freely volunteers and I love it. It does have a tendency to flop later in the season so I make a roll of chicken wire, 8-12" diameter to surround the plant before it gets big. The stems will come through the wire, too, and can completely hide the wire.

This is the easiest Hardy Geranium to grow here in SoCal.

Likes a bit of afternoon shade.
But tolerates all types of soils, from fast-draining to clay.

As many have noted its Spring bloom is the most prolific.
The Fall and Winter foliage color, however, is very appealing.

In a favorable, protected spot its leaves get enormous and lush.

One of my favorite plants, in zone 7-8, it is very self-sufficient. I only water during the worst of summer heat. Blooms early summer, has a nice mounded growth habit. Has tolerated being overrun, first by Blue Star Creeper and another time by Vinca Minor. Volunteers are easy to transplant. Color is intense.

Cranesbill is always welcome in my garden. I've had them in various gardens and all have seemed to survive even the toughest conditions. The ones I'm tending now in good conditions are thriving. They bloom profusely and give a nice display just after the daffodils and tulips of early spring fade. Not only are they long-blooming but they continue to rebloom sporadically throughout the summer and into the fall. The first bloom is the best, but any rebloom is, of course, welcome!

Although I don't believe deadheading promotes rebloom, I tend to groom my cranesbill a bit from time to time to keep it tidy and compact. Cranesbill also gives my garden a flush of fall color when its foliage turns a deep ruby red.

Nice clump, can get a little scraggley in late summer so it gets trimmed then.

We enjoy this perennial alot as the folliage is springy and is good ground cover. It repeated blooms throughout the growing season,(more dense blooms in the spring). The blooms are almost iradescent.

I have a couple of blooms on this one in December--much to my surprise--in Zone 7. I've had the plants (grown from seed) for three or four years and have enjoyed watching them grow in partial shade among tree roots. Interestingly,
some of the plants are now quite red, while others (including the one with blooms)are a strong, dark green.


On Mar 13, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

Profusely blooming during early to mid-summer. Flowers are cup-shaped, red/purple with dark veins - measuring 1-2 inches across. The long, slender beak-like fruit gives Cranesbill geranium its common name. Plant in well-drained soil and provide afternoon shade, especially in hottest climates.
