There are now three varieties of ever-bearing mulberries presented to us for selection or for general adoption.
Downing's Ever-bearing is a seedling of the Multicaulis, which it resembles in wood and foliage. It is therefore necessarily somewhat tender, and not suited to a more northern climate. Mr. D. has given us an ample description of its fruit in his "Fruit-Trees of America," and merits much credit for originating so excellent a fruit.
HerbemonVs or Hicks's Ever-bearing is a much hardier variety, and superior to the preceding in size and quality of its fruit, which is produced during a considerably larger period of time. It is a prodigious bearer; the berries are usually nearly two inches in length, sweet and delicious. At the South the fruit continues ripening from the 25th of April until the 15th of August, and here at the North the crop extends to a late period in the autumn. This tree has dark red wood and indented leaves, very distinct from Down tag's.
White Ever-bearing^ sweet berries, partakes considerably of the character of the White Italian. It grows vigorously, and yields immense quantities of fruit.
