The individual leaves on this burdock are more than two feet long, as it builds up energy in its roots to flower next summer. (This less-common pattern marks it as a biennial plant., rather than an annual or perennial.)

I love the thistle-like flowers on our burdock plants!

Another reason I like burdock is that it supports a lot of insects. A week ago, I noticed that seemingly overnight, the undersides of the flower clusters had been swarmed by hundreds of aphids. I pulled out the hose and blasted a bunch of them off with a few quick squirts, but that only thins them out, it never gets ’em all, so I was very pleased to find a couple of ladybugs crawling around on it the next day. Although they’re cute, I know they’re fiends for aphids.

And even better, by the end of the week I was seeing ladybug larvae crawling around, clearing out the lingering aphids. A few days later, I can no longer find any aphids at all.
