Gardeners' Notes:

Neutral ButterflyGardnr On Jul 20, 2003, ButterflyGardnr from Orlando, FL (Zone 9b) wrote:

I have just planted this plum tree this spring. It had a decent bloom, but did not produce any little plums as I had hoped. The bees were very attracted to the flowers. The bark is a deep, shiny mahogany color typical of the plum and cherry trees. The tree will drop its leaves in the fall, flower in early spring (~ Feb. in Zone 9B here in FL), and then leaf out for the summer. Birds like the small fruits and they are edible to humans, though they can be somewhat sour/bitter. I am waiting to see what this tree does next spring after it has had a chance to get established a little bit.
