Although neither our alkaline clay-ish soil nor our zero humidity screaming hot summers are friendly toward them, I have a never ending friendship with the hardy geraniums, specifically the genus Geranium, not the pelargoniums we casually call geraniums. As they are not as common in California as other parts of the US I cannot resist buying almost any one I see in my gardening travels and am guilty of not always doing my research before swiping my credit card.
Three years ago while on my first Garden Conservancy Open Days jaunt I visited Digging Dog Nursery in Albion, CA near the Mendocino coast. My post Mendocino madness…#2 will give you a glimpse of Deborah Wigham and Gary Ratway’s wonderful demonstration garden, retail and mail-order nursery flourishing in a forest near sea level in Northern California. They have great selections in small sizes so it’s easy to try a lot of different plants for not such a huge investment. One of three hardy geraniums I purchased there is Geranium nodosum ‘Clos du Coudray’, named after a famous garden in the Normandy region of France. G. nodosum spreads by underground rhizomatous roots to form medium sized mounds and is indicated to use in medium to light shade area. My reference material–which I had with me to consult as I shopped–states “At least two sources have reported G. nodosum can become very invasive and that it is very difficult to eradicate.” Well, I have made a few missteps in the past on planting things purported to be invasive–the dreaded Lippia nodiflora (AKA Lippia repens AKA Phyla nodiflora) took years out of my gardening life to finally see the last of it after I blithely planted a 4″ pot in a rose bed needing ground cover, foolishly believing I could confine it with a brick edging. It not only overtook the bed but also everything else planted in it. Hoping to not have a repeat of that messy situation I planted little ‘Clos du Coudray’ in the Secret Garden behind our outdoor pavilion where I thought it could not do lasting harm if it ran amok under the sequoias. I never saw it again until today. After its almost immediate disappearance I have periodically checked the ground near the ID tag for signs of life three or four times a year since the summer of 2016. Nothing, nada, zilch.
Like Lazarus, the little jewel has risen from the dead. It actually looks as though this might be its second bloom, albeit only a single bloom stalk (stem? whatever!) With nine leaves I think I am in no immediate danger of the area being overrun! I will keep a close watch over it though as it has had almost three full years to build up its strength.
