At this time of year, the Aster (Aster nova-belgii) blooms,
and it has become known as the Michaelmas Daisy.
An old verse goes like this:
The Michaelmas Daisies, among dede weeds,
Bloom for St Michael's valorous deeds.
And seems the last of flowers that stood,
Till the feast of St. Simon and St. Jude
The Feast of SS. Simon and Jude is 28 October
