The time for snowdrops is with us now. This is not a native to England but introduced and now naturalised to some extent. Theophrastus talked about them although he may be referring to another flower.
τὸ λευκόιον, ὅπου μὲν ὁ ἀὴρ μαλακώτερος εὐθὺς τοῦ χειμῶνος, ὅπου δὲ σκληρότερος ὕστερον, ἐνιαχοῦ τοῦ ἦρος.
The snowdrop, where the climate is milder, flowers at the beginning of winter but where the climate is harsher later, sometimes during spring.
Theophrastus Enquiry Into Plants 6 VIII
I took this photo yesterday at Swyncombe church. The snowdrops are still not yet tin their full glory but still very nice growing in between a few patches of snow. Not the best of photos I admit.
