Native and non-native bluebells – an update
by The blog at woodlands.co.uk, 24 April, 2023, 4 comments
The onset of Spring brings a variety of blue flowered plants such a bluebells, hyacinths and squills in our gardens, parks and woodlands. The bluebell is ‘easily’ recognisable. However, there are two or three different types of bluebells. The bluebell that is native to the UK has the Latin or Linnaean name of Hyacinthoides non scripta.
Its deep blue and scented flowers hang from an elegantly arching stem. It is found in abundance in many deciduous woodlands and hedgerows across the UK, though it is unusual or rare in parts of East Anglia and Scotland. The Spanish bluebell (H. hispanica) is also to be found.
It is possible to distinguish between the two species – some of the differences are listed in the table below:
Native Bluebell
Spanish Bluebell
Leaves are narrow by comparison to Spanish Bluebell, about half an inch or so wide
Leaves broader, often an inch or more wide
The flowers at the top of the stem droop to one side
The top of the stem is much more erect
The flowers hang from one side of the stem
The flowers are arranged around the stem
The flowers are deep violet blue
The flowers are a pale or mid blue, and white and pink ones are also found
The flowers have parallel or straight sides and have a narrow bell shape
The flowers are more ‘open’ with a cone shaped bell
The tips of the petals roll back somewhat as though they ‘want’ to touch the tube of the flower
Not such obvious curving
The pollen is a pale cream colour
Pollen is a blue colour
Flowers are scented
No scent detectable
The spanish bluebell can hybridise with the native bluebell, giving rise to types that have a mixture of the above characteristics.
The Natural History Museum is trying to map the distribution of these different bluebells and it is asking people to complete an online questionnaire about the bluebells in their gardens, local parks, hedgerows and woodlands.

Since this was first posted in 2006, there have been various updates, but the bluebell survey link does not seem to be active now.
