Bluebells make a lovely carpet of blue especially in a woodland setting and are quintessentially British. In fact about half the bluebells in the world are grown in the UK and they are a very popular plant.
In the right conditions, Bluebells grow themselves and take care when planting them as they can be prolific. Bluebells can be planted in the spring as plants, or more economically as bulbs in the Autumn. if planting them in the green as growing plants, re plant so the soil is at the same level, which means all the white part of the stem is buried underground. If planting as bulbs, around 10cms deep, pointed end uppermost. Water well after planting.
Bluebells can take a little while to get established. Once established they can out compete all other plants and take over and be difficult to eradicate so take care where you plant them. In some conditions they can be considered weeds .
Bluebells are a woodland plants so do best if such conditions are recreated such as shady, moist conditions which does not dry out during the summer.
Avoid the impostor, shown above the Spanish bluebell. It is even more vigorous than the English variety, (if anything could be) and the natural movement of pollen by bees will cross over to with the English variety to contaminate the strain.
