I would appreciate help in identifying this bloom—Leucojum vernal (spring snowflake) or Leucojum aestivum (summer snowflake)? I have not been able to figure out what characteristics to focus on to distinguish between the two.
[Update Mar 12, 2016: Thanks to my helpful readers for identifying this as Leucojum aestivum.]
Although it will be 80°F. today, it is not summer yet, but in my records I have these labelled L. aestivum (summer snowflake). They are pass-alongs from Sisters’ Garden so it must have been a guess.
They were planted in the green March 21, 2014 and bloomed April 30, 2014. Last year they flowered by March 30. So here they are in 2016 three weeks earlier, closer to spring than summer.
Thanks for your help.
