Other Plant Names: Guapuru, Hivapuru, Sabara, Ybapuru
Species: Myrciaria cauliflora Berg., M. jaboticaba Berg., M. tenella Berg., M. trunciflora Berg.
Related Species: Guavaberry, Rumberry (Myrciaria floribunda), Yellow Jaboticaba (M. glomerata), Camu-camu (M. paraensis). Blue Grape (M. vexator).
Distant affinity: Eugenias (Eugenia spp.), Feijoa (Feijoa sellowiana), Guavas (Psidium spp.).
Origin: All four of the jaboticaba species are native to the Minas Gerais region of Brazil. Some are also indigenous to other parts of Brazil, as well as areas in Bolivia, Paraguay, northeastern Argentina, Uruguay and Peru. In Brazil jaboticabas are cultivated from the southern city of Rio Grande to Bahia, and from the seacoast to Goyaz and Matto Grosso in the west. It was introduced into California (at Santa Barbara) about 1904.
Adaptation: In Brazil jaboticabas grow from sea-level to elevations of more than 3,000 ft. Different plants vary markedly in how much frost they can take without severe damage, probably reflecting the species that a given plant belongs to. Some plants can take 24 degrees F or lower and survive; others are damaged at 27 degrees F. In 1917, a young tree at Brooksville, Florida survived a temperature drop to 18 degrees F. with only the foliage and branches killed back. In California jaboticabas have been successfully grown in San Diego, Spring Valley, Bostonia, Encinitas, South Los Angeles and as far north as the San Jose and San Francisco Bay areas. The plant makes a suitable container specimen.
DESCRIPTION
Growth Habit: The jaboticaba is a slow growing large shrub or small, bushy tree. It reaches a height of 10 - 15 feet in California and 12 - 45 feet in Brazil, depending on the species. The trees are profusely branched, beginning close to the ground and slanting upward and outward so that the dense, rounded crown may attain an ultimate spread as wide as it is tall. The thin, beige to reddish bark flakes off much like that of the guava. The jaboticaba makes an attractive landscape plant.
Foliage: The evergreen, opposite leaves are lanceolate to elliptic, 1 - 4 inches in length and 1/2 - 3/4 inch wide. In color they are a glossy dark green with a leathery texture. The size, shape and texture varies somewhat from one species to another.
Flowers: The small yellow-white flowers dramatically emerge from the multiple trunks, limbs and large branches in groups of four. It has been reported from Brazil that solitary jaboticaba trees bear poorly compared with those planted in groups, which indicates that cross-pollination enhances productivity.
Fruits: Jaboticaba fruit is grape-like in appearance and texture but with a thicker, tougher skin. Most California fruit is dark purple to almost black in color. Averages size is one inch in diameter but can run from 3/4 to 1-1/2 inches, depending on species and variety. The gelatinous whitish pulp contains from one to four small seeds and has a pleasant, subacid flavor markedly similar to certain muscadine grapes. The skin has a slight resinous flavor that is not objectionable. Fruit may be produced singly or in clusters from the ground up all over the trunk and main branches, and the plant may fruit up to five times per year. Fresh fruit is delicious eaten out-of-hand and can be made into jellies, jams and wine. The skin is high in tannin and should not be consumed in large quantities over a long period of time.
