Illinois Everbearing mulberry
Morus alba x rubra
This grafted tree is hardy to -30 deg.F. It sometimes starts producing the first year after planting and bears an abundance of sweet, highly flavored fruit, 1-1/2 inches long x 1/2 inch wide that look like elongated blackberries.
The fruit has a delicious distinctive flavor. The berries ripen continuously throughout July, August, and September, hence its name. The fruit is red and turns black when ripe.
Illinois Everbearing will grow to 35 feet tall but it is easily pruned and kept much smaller. Each is self-fertile.
