Blue Grape from Fruitipedia, Encyclopedia of the Edible Fruits of the World
The blue grape is an exquisite landscape specimen that bears a delicious grapelike fruit. The species is obscure and only available from specialized sources. Some consider the fruit slightly innferior to that of the jaboticaba, although it is of very good quality and pleasant flavor. As a result of its many attributes, the blue grape has excellent potential as a dooryard tree for south Florida. 1
The bark, which is decorated with a reticulated patten, occasionnaly peels in large patches (Fig. 11), revealing a light undercoat. The tree is handsome, ornamental, and well behaved, and would be worth planting for its aesthetic value alone. 1
The bright green leaves, which measure from 3 to 5 inches in lenght, are opposite, entire, oblong-lanceolate, and pointed at the apex. They are glossy, slightly folded along the central axis, and point stffly downward. 1
Flowering occurs in 2 or 3 waves, often in late winter of early spring. The small white flowers appear both on older branches and on new growth. It is thought that cross-pollination is needed to ensure adequate fruit set. 1
The fruit of the blue grape is a thick-skinned berry, measuring from 1 to 1 1/2 inches in diameter. The skin changes from bright green to a dull bluish-purple as the fruit ripens. The rind is tough, rubbery and inedible. The pulp is gelatinous and somewhat translucent. The color of the pulp is whited tinged with pink or orange. The flavor is sweet and mildly aromatic. 1

The blue grape is harvested when fully colored and slightly soft to the touch. The main crop matures in the spring, although fruit may be present throughout the warmer months. 1
Seeds are slow to germinate, sometimes requiring 3 or more months to sprout. 1
It requires regular irrigation during establishment, but appears to have greater drought tolerance than the jaboticaba. 1
The blue grape is relatively free of pests and diseases in Florida. The skin of the fruit is sufficiently tough to resist attack by the Caribbean fruit fly. 1
The fruit is usually eaten out of hand, with the pulp sucked from the rind. The rind and seeds are discarded. The fruit spoils and dehydrates rapidly once it has been picked. 1
