My so-called snowflakes are very tall (daffodil height) with snowdrop heads. They are just finishing flowering. They come back every year and grow n clusters. What is their name?

Hi Lynne and welcome to a great website! Our snowdrops are much shorter than daffodil height, usually around 4 to 6 inches. We don't have any snowflakes, although they look very lovely and if I come across them they may well end up in our garden!
Here's an old BBC article on the relationship between the two:

I'd be interested to see a photo of your snowflakes, if you have one?

Leucojum . Snowflakes do get tall ours are 12-16" tall vs my snowdrops that are 3-5"

Summer Snowflake (Leucojum aestivum 'Gravetye Giant')
