I hope it works! I learned this year that my "Rozanne" Geranium blooms from spring until winter but it seems my Bevans only blooms spring into early summer. I like that the Rozanne also spreads and intertwines among other, non-blooming, plants to add some surprise color.

I am under the impression that BEVANs is 'hardier'/tougher than Rozanne and so more likely to hold its own under such adverse conditions.

Any variety of Geranium macrorrhizum is far better adapted to the dry shade conditions present under a large maple than 'Rozanne', which is a sterile hybrid of two not particularly shade tolerant species.

Epimediums would be another good choice for dry shade.

It is *my* experience that macrorrhizum geraniums do 'better' than epimediums in these planting conditions.

Epimedium works right up to the trunk of my mature Maple. Very little else, except vinca.

I find epis to be somewhat slower to spread and form colonies but a much more interesting plant than a bigroot geranium IMO.

When I first started buying epimediums, I stuck to clumping varieties, worried they might spread too much, then switched to trying to find those that travel more. There are some. I have one that has a gorgeous red fall/winter color to the foliage too. Clearly, they don't offer a long bloom period and are plain vanilla most of the season, but for me, they are carefree, with no maintenance. I can even fail to cut back the dead foliage in the spring and the new foliage will grow up and cover that for the most part. Haven't noticed insect or disease damage ever and they are very drought tolerant.

I have Bevan's variety seeding into places epimediums are dying off because they can't handle the shade.

Is this Google image, what Bevan's variety looks like? I have 'Karmina' that might look similar at least in color. How long a bloom period does that have?

I have a small shared front yard with our neighbour. We each have a city planted Norway maple, by now more than 40 years old. A yellow spreading epimedium (sulphurea?) and Solomon’s seal barely hold their own, a few hostas grow well now, after years of struggle, and the easy successes are Digitalis lutea, G. macrorrhizum, and a self sown wild goldenrod. I have to control the runners of the last one every spring, and deadhead it in the fall, but it is showy, and blooms well right up to the trunk.
