California and Arizona tangelos have a slightly pebbled texture, good interior and exterior color, very few seeds, and a tight-fitting rind. Orlando tangelos are available from mid-November to the beginning of February. It originated as a cross between a Duncan grapefruit and a Dancy tangerine.When the Orlando tangelo was first cultivated, it was known by the name Lake tangelo. The trees of this variety grow to a large size and are easily recognized by their cup-shape leaves. Orlando tangelos are recognized as one of the more cold-tolerant varieties. Northern Florida grows significantly fewer tangelos, but they are much sweeter due to climate.
