Good timing is essential when trying to catch bluebells at their peak. They tend to be best at the end of the flowering season in April/May but only a week separates stunning carpets of blue from the fading green of setting seeds.
The video shows what you might see during the bluebell flowering season and the graph shows how bluebell quality (flower density) varies with time. 2020 saw a milder winter than 2016 and a very warm and sunny spring. The bluebells flowered about one week earlier than usual in 2020.
Whilst you will see a few bluebells in the first two weeks in April you are far more likely to get a good show in the second half of the month. Bluebell quality rapidly declines after the first week in May and within the space of a week the bluebells suddenly disappear.
The timelapse was taken in Ashplats Wood, East Grinstead, West Sussex, UK during 2016. This followed a typically mild winter in the south of England. Bluebells flower slightly later after a cold winter or at latitudes further north.
In Australia, New Zealand and other parts of the Southern hemisphere the best time to see bluebells is between the end of October and the beginning of November.
