One of my favorites when I think of spring is Japanese apricot or Ume in Japanese (Prunus mume). Its flowers open up in February in Japan. When I was in Japan, it was often Ume that informed me the arrival of spring.
There are many beauty spots for Ume throughout Japan. Kitano Tenmangu, a famous shrine in Kyoto, has The Plum Blossom Festival on February 25. Planting Ume should be OK in Connecticut although I have hardly seen it.
I am waiting for spring. But when I see flower blossoms, I should go get a drug for my hey fever. (T)
