Gardeners' Notes:


On Oct 18, 2014, coriaceous from ROSLINDALE, MA wrote:

This cultivar is a sterile hybrid between G. sanguineum and G. psilostemon. Deadheading is unnecessary and does not help extend bloom. It grows larger than G. sanguineum but in other respects it's very similar.

Tiny Monster grows just fine for me in zone 4a. It gets taller than I expected and blooms all summer if deadheaded. The foliage is very nice and the flowers are a very bright and beautiful color. They seem to do well in sun, shade, or anything in between. This is a really great hardy geranium!

grows in full sun here and blooms profusely all summer long. Got this plant in 2006 and this is the first year it has gotten tall. Stayed very low and sprawlish before, now it is more upright. LOVE this plant and would highly recommend it for its growth pattern as there are no bare centers with this plant and for the brilliant color the flowers provide.

Very unusual geranium - it keeps blooming all the way into fall. Not profusely, but the flowers are so vivid that they are a real treat during the late summer doldrums. This one really spreads its leaves, all the way to four feet until I pruned it back.

This is a delightful little plant that creeps along the ground. I had expected it to grow into a 12" size plant, but having not researched it before I purchased it, I just enjoy it. It's different from my other geraniums, but I like it!
