Bordered by large birch and beech trees, much of my garden is shady like an open woodland, and the bluebells really seem to like it. Sadly, I have the Spanish version (Hyacinthoides hispanica), rather than the native Common Bluebell (Hyacinthoides non-scripta). The non-native species has broader leaves, more upright flower stalks as the flowers form on both sides of the stem and a more open, less bell-shaped flower. They also lack a scent, which perhaps makes them less attractive to insects, though I do see bumble bees and bee flies visiting them. They are also much more fast-growing than the native bluebell, quickly spreading across the borders and given half a chance into woodlands, where they also pose a risk to the native species through hybridisation. I should I suppose pull them out and replace them by some native ones, but if I do I will wait until after they have flowered, as they are pretty.
