Characterised by apple-green, lobed leaves and flat heads of cream-white flowers in summer, ground elder spreads rapidly. What makes it even more difficult to eradicate is it can creep between cultivated plants. It creates large clumps of foliage that obscure and smother smaller plants. Ground elder dies down below ground in winter, which means it's difficult to spot when cultivating the soil. However, it's capable of re-growing from only small fragments of root, making it a particularly virulent plant.
This vigorous, spreading perennial is rampant, growing over cultivated plants and making them compete for light, water and nutrients.
