Snowdrop Windflower is a beautiful spreading perennial suitable for mass planting. I would not advise to plant this if you plan on not maintaining your garden as it does spread my underground roots and by seed. However this is not an aggressive spreader as Quack Grass (Elytrigia repens) and even if it does spread more than you want, you would be hard pressed to find a more beautiful weed.
This is also great used around your spring flowering bulbs as when your tulips or daffodils die back this anemone will start to take off right when the bulb foliage that you should be leaving attached for the health of your bulbs are not looking good at all.
Deer and Rabbits also won’t want to nibble on these, and they are great naturalized in a wooded area and meadows where our unwanted nibblers like to hang out.
The Snowdrop Anemone does like moist soils, so make sure you plant it in the right area for it to thrive or you will be watering it to keep it looking nice.
