These are fairly new additions–I ordered two of them from Annie’s Annuals in fall of 2018. The plants have grown together into a big mounded plant that right now is completely covered with blooms. Last fall, they bloomed for months on end. There is lot to like about a plant that blooms for that long. The foliage, when you can see it through the blooms, is handsome.
Geranium May 2019 
I also started seeds of the species Geranium pyrenaicum and ended up with one plant which I transplanted to the garden at the same time I planted the “Bill Wallis” duo. This seedling has very similar if less prolific flowers. The place it seems to be outshining the named variety is in volunteering. In fact, I’m on the verge of rooting it out altogether because there are dozens of babies near the parent plant. Is it generous or dangerous?
For 2020, I’ve already fed these plants with organic food and will follow up in a few months with more food and a shredded leaf topdressing in the fall.
