Description

This is part of a series of observations of the same specimen:

If I remember correctly, somewhere around the time of this observation I began to regularly prune the branches as they were starting to block the only pathway to our backyard.

I also pruned the bottom-most branches heavily so that our dogs could go underneath this plant, instead of around it (and too close to the sharp metal edges of our downspout for my comfort). Keep this in mind if you're comparing the overall size and form of the plant over time.

Interesting how you can see the long stems the plants grew when the river was 1-2 ft higher a couple weeks ago and now they are sitting on the ground. Vigorous new growth though.
