Abstract
A distinctive Southern Live Oak tree is provided which was discovered as a chance seedling at Brooksville, Fla., U.S.A. The new variety is well-suited for growing as an easily-maintained quality shade tree in the landscape. The tree is a very rapid grower and displays a generally upright and substantially uniform and dense growth habit with a dominant central leader when mature. The lateral branches commonly are disposed at angles of greater than 60 degrees from the vertical in the substantial absence of included bark. Attractive dark green elongated and narrow leaves are formed which are glossy on the upper surface.
