Sometimes you'll find flower thugs lurking in your perennial garden. These are the plants that just grow and spread. They start out small, but before you know it, they've taken over the whole garden!
The first thug that's blooming now is valerian. It was actually brought over from Europe in the 1800s as a medicinal herb. It's a beautiful, tall, white flower but it's got a not so great smell. It's a nice flower to attract beneficial insects into the garden. If you want a better smelling valerian, try pink valerian or Jupiter's Beard, a red valerian. These are nice, but will spread all over the place so watch out.
Here's a yellow flower that's blooming right now. It's called sundrops. They look like the giant buttercups. They're an evening primrose, and they will spread all over the place by their root system. If you pull them up you can see the roots and how they spread. Even if you dig them all up this year, you're still going to have some pop up next year. If you want to grow this one, look for the white or the pink flowered versions of them. They're less invasive.
Finally, there's the Canadian anemone. It's a beautiful white little flower, grows well in part shade, and in damp conditions but again, it spreads all over the place so be careful!
If you are planting any of these, its good to put them in the right location. Grow them next to a building or on a lawn so you can keep them contained. Put them in their own bed or you'll be really weeding them out for years to come.
