Interesting Information About Plant: 

            The Bloodgood Japanese Red Maple was introduced into the United States before World War II.  It is a cultivar named after the Bloodgood Nursery in Long Island, New York, where it was developed.  The Bloodgood is commonly planted in gardens as an ornamental tree and is admired for its graceful and peaceful appearance.  The Bloodgood has beautiful burgundy foliage its entire growing season and has small, but attractive red fruits.  It can grow 15 to 20 feet high and has a spreading habit.  The Bloodgood is a strong growing plant and may grow 2 to 3 feet per year.  It is an easy plant to grow, especially because it does not require large amounts of nutrients, and overall has very few problems.  It is a noncompetitive plant and can still grow very well if surrounded by many other plants.  The Bloodgood requires direct sunlight for as least part of the day, but also needs partial shade.  In extremely hot and dry weather, it can be sun burned and become tattered.  The Bloodgood has a strong fibrous root system, multiple stems, and slender shoots that end in small paired buds.
