Cutting back Geranium maderense.

There comes a point where Geranium maderense finally exhausts itself and starts to look pretty ugly. Its beautiful architectural leaves and reflexed petioles that once helped to hold the plant up finally shrivel and the plant collapses under its own weight. Thousands and flowers and seeds take up a lot of resources.

“When should I cut this beast back?” I wondered.

It got a brief stay of execution when a male California quail decided it was the perfect spot to watch out for danger.

He would watch attentively as the rest of his covey ate in the garden below and cry out if he saw any danger.

When the quails stopped coming around the plant got another stay of execution when it threw out a new flush of blooms but finally it fell over and I decided it was time to go.

The branches of the inflorescence are massive. I had to prune them off one at a time and then untangle them from each other.

They are a little bit unpleasant to work with because they are covered with little glandular hairs that secrete a sticky sugary substance.

The leaves from the main stem are all dried up and dead. The leaves you are seeing here are from two pups. Lower side branches from the base of the plant. I wanted to save one of them so I had to work carefully so I wouldn’t damage it.

Here you can see the old leaf petioles flushed against the trunk. They start out upright and as the plant grows taller the lower leaves reflex and act as a support for the plant. They do a pretty good job at it. The main stem gets three to four feet tall and at least another two feet while in bloom and is quite top heavy. But the leaves helped hold mine up in 30-40 mph gusts of wind.

This is the base of the plant where you can pretty clearly see that the pups are new stems coming from the base. I have had people insist that the plant is completely monocarpic and that my pups were just seedlings but obviously that is not always the case.

I carefully sawed off the main trunk and the weaker pup and saved the one that was more upright.  It has been doing fine and should hopefully bloom next year. Not a problem if it doesn’t make it as there are tons of seedlings already germinating. It is definitely a bit weedy but the seedlings are large and distinct so they are pretty easy to thin out or remove.

  1. I didn’t have your patience — just yanked its sorry carcass out of the ground. As you say, tons of seedlings everywhere.

  2. It’s possible I have posted this three times. Sorry!
    I just wanted to let you know that it makes my day to see that you have posted. This was, as usual, quite interesting. I had never realized how these plants work.

  3. I just rip them out. Plenty of seedlings. You are very patient! Ditto on the Quail shots–love those guys.

  4. Hi Kaveh, I recently discovered your blog and subscribed. I really enjoy the content and your enthusiasm for horticulture ! One thing I noticed was the photos tend to load slowly which could be rectified by reducing the resolution ( 3 r’s haha ). Thanks, hope that helps.
