Even where no freeze damage occurs some people cut it back to about 4 feet each year to force the leaves to be closer to the ground for ease of harvesting. If not forced to branch by pruning, the tree becomes tall, spindly and not very attractive. We do not recommend it as a prominent shade tree. Aside from eating the leaves, very young pods can be cooked and eaten like asparagus. Pod production is variable and seems to be increased by stress.
Some trees bloom at less than a year old and others take longer.
Blossoms are edible and taste similar to a radish. When trees are about 3-4 feet tall they can be pulled out of the ground and the roots grated and used like horseradish. The root bark is toxic and should be peeled off before grating. Only eat the roots in moderation. Crushed raw leaves may irritate the skin and if eaten are purgative.
