'''Adaptation''': The tropical guava is best adapted to the warm climate of Florida and Hawaii, although it can be grown in coastal Southern California, and with some protection, selected areas north to Mendocino County. Guavas actually thrive in both humid and dry climates, but can survive only a few degrees of frost. The tree will recover from a brief exposure to 29° F but may be completely defoliated. Young trees are particularly sensitive to cold spells. Older trees, killed to the ground, have sent up new shoots which fruited 2 years later. Guavas can take considerable neglect, withstanding temporary waterlogging and very high temperatures. They tend to bear fruit better in areas with a definite winter or cooler season. The adaptability of the guava makes it a serious weed tree in some tropical areas. The smaller guava cultivars can make an excellent container specimen.

'''Fruits''': Guava fruits may be round, ovoid or pear-shaped, 2 - 4 inches long, and have 4 or 5 protruding floral remnants (sepals) at the apex. Varieties differ widely in flavor and seediness. The better varieties are soft when ripe, creamy in texture with a rind that softens to be fully edible. The flesh may be white, pink, yellow, or red. The sweet, musky odor is pungent and penetrating. The seeds are numerous but small and, in good varieties, fully edible. Actual seed counts have ranged from 112 to 535. The quality of the fruit of guavas grown in cooler areas is often disappointing.

Guava. The name guava is applied to the fruit of various species of Psidium, frequently with the addition of a qualifying word such as apple, pear, Cattley, to distinguish different species and varieties. In Spanish it is guayaba, in Portuguese goiaba. and in French goyave (the plant goyavier). In Brazil the name araca, with qualifying words, is applied to a number of wild species.

In California P. guajava frequently suffers from the attacks of the black scale (Saissetia oleae), which must be kept in check by fumigation or spraying. In other countries this plant seems remarkably free from insect pests or fungous diseases, and this is true also of the Cattley guava. The fruits are sometimes injured by the Mediterranean fruit-fly, and a scab has been observed in Brazil which affects them prejudicially. As a rule, however, the plants require little attention.

Psidium (Greek, psidion, the pomegranate). Myrtaceae. A large group of tropical and subtropical trees and shrubs, all native to America, many of which produce edible fruits. The common guava of the tropics, P. Guajava, is the best known. It has become naturalized in many parts of Asia and Africa. See Guava.
Leaves opposite, petiolate, glabrous, pubescent or tomentose, pinnately veined: fls. usually rather large, whitish, on axillary or lateral 1-3- (rarely many-) fld. peduncles; calyx-tube urceolate or pyriform, lobes 4-5. persistent; calyx sometimes closed before anthesis and splitting irregularly into 2-5 lobes; petals 4 or 5, spreading; stamens numerous, disposed in many series and inserted upon the disk, filaments filiform, anthers oblong or linear, basifixed, longitudinally dehiscent; ovary with 2-7, commonly 4, locules, the style slender, stigma peltate or subcapitate: fr. a berry, ovoid, globose or pyriform, commonly 1-3 in. long, yellow to red in color, sometimes green, crowned with the calyx- limb; seeds few to numerous, small, hard.—About 150 species. The genus is somewhat confused and in need of further study. A large number of species doubtless exist in S and Cent. Amer., which have not as yet been described. The genus is allied to the myrtles (Myrtus), the pomegranate (Punica), and the various Eugenias, of which a number are cult, in the tropics for their frs. The following treatment includes the principal ones known to horticulture.
A species intro. by Franceechi under the name of P. acre. Ten., resembles P. Cattleianum var. lucidum, but has more elongated and usually larger frs. The foliage is of the same type.—P. dichotomum, Weinm., is properly P. Araca: a species intro. by Franceschi as this species is evidently something else, having broad coriaceous, glabrous lye. and somewhat resembling P. Cattleianum in habit.— P. guayabita, A. Rich., is a species recently intro. from W. Cuba, where it grows wild: the frs. are small and not considered very valuable.—P. guianense, Pers., is a synonym of P. fluviatile, Rich., a species with branchlets terete, glabrous: lvs. oval, glabrous: pedicels opposite, 1-fld. Cayenne.—P. guineense, Swartz, is a synonym of P. Araca, Raddi, according to Berg, but DeCandolle considers it a distinct species. He distinguishes it from P. Araca by the lvs. less soft, glabrous above, with the nervation not raised as in the latter. More recently Urban uses it in preference to P. Araca, which latter is made a synonym; he states that it resembles P. Guajava, but is easily distinguished by the less numerous transverse veins, not impressed above. Swartz, in describing P. guineense, stated that it came from Afr., and was cult, in Santo Domingo, but as all psidiums are now known to be American, he was doubtless mistaken regarding its origin.—P. littorale, Raddi, intro. by Franceschi, resembles P. Cattleianum very closely, but has lvs. somewhat more attenuate toward the base, and obovate or pyriform frs. Berg (in Linnaea, xxvii) groups this species, P. Cattleianum and P. humile together under the name of P. variabile. S. Brazil.—P. montanum, Swartz, is a species from the mountains of Jamaica, with 4-angled branchlets: lvs. oblong-oval, acuminate, glabrous: peduncles many-fld.: fr. subrotund.
