A daisy dilemma

I planted a perennial garden several years back. In the past two years, the Shasta daisies have spread and are taking over the whole garden. I have dug several up but the roots are numerous. Should I just spray them to kill them?

DaisiesWhen you read comments about Shasta daisies on garden websites, it’s clear that gardeners either love them or hate them. Love them because these daisies (Leucanthemum, in botanical nomenclature) are easy to grow and bloom reliably year after year; hate them because they can be aggressive and can, indeed, muscle out plants that are more well-behaved.

Japanese anemone can be an attractive nuisance

We planted Japanese anemone a few years ago and it’s beautiful now that it’s blooming again, but it’s also spreading all over the place and taking over the garden bed! We’ve tried digging it up and cutting it back, but it just grows more. What can we do to keep it from spreading?

Japanese anemoneHere is an example of a plant that you can fall in love with once a year. The rest of the year, you may find you want to rip it out of the ground.

Japanese anemone has a lot to recommend it. It’s a perennial that grows in sun but is also happy in partly shady conditions. It doesn’t mind acid soil. The foliage grows tall (2 – 4 feet) in attractive mounds. Deer and rabbits don’t seem to care for it, and it blooms reliably in fall, opening masses of pretty white or pink flowers that sway in the breeze after summer-blooming perennials have given up for the year.

It’s a little finicky about soil; it requires good drainage and may languish during periods of drought, but the main complaint gardeners have is that it’s aggressive. It can take a couple of years for it to get established, but once it’s settled in and conditions are right, the plant spreads rapidly and forms dense clumps that take over whatever else might be in its way in the garden bed. Some have called it, generously, a “nuisance” plant.

Here in Zone 7a, Japanese anemone dies back after frost but it’s one of the first things to peek out of the soil in later winter, and once the weather warms, it takes off again. In my garden, it comes up through gravel paths, between rocks in a stacked stone wall, and is making its way into nearby raised beds in the kitchen garden.

It takes diligence and a sharp tool to keep it within bounds. Where you don’t want it to grow, dig it up. Try to get as much of the root as possible (which can be difficult, because the roots break easily). If you want to divide it to share with friends, spring is a good time for that task. Be sure to warn anyone who receives your gift of Japanese anemone that it can become an attractive nuisance.
