Magnolia stellata

Detailed in my book "All Year Plants in Flower" as plant number 30 so listed in week 10 so just about spot on this year despite the fact that many have been flowering early.
Interesting to note that the next plant in the book (31) is Aubrieta and the plant photographed in the book is scarcely in flower. Muscari is plant 32 and has been flowering for several weeks.
