Fall Bananas?

Last week when I was in the backyard, I noticed a huge purple bud on the banana trees. This morning it bloomed...two bunches of bananas! It seems strange to me to see them blooming so late in the season. The weather has been so odd this fall. The plants are so mixed up. The other day, I saw some pear trees with white blossoms all over them. It looked like it was spring.
