Single to multi-stemmed shrub or small tree.
30-40 years, but productivity declines after 15 years.
Moderate to rapid.
6-12' high and as wide. In wet topics, can reach 30'.
Five white petals, with hundreds of white stamens tipped
with pale yellow anthers. Petals drop quickly, leaving hairy tufts of stamens.
Spring and early fall. Under right location and weather conditions,
may bloom nearly all year.
Yes, but some cultivars produce more fruit when
cross-pollinated with another cultivar.
Years before fruiting:
Light green or lemon yellow when ripe, round, oval or pear-shaped,
2-4" long. Guavas are often placed in two categories: white (or yellow) flesh
and pink (or red) flesh.
The white are sometimes eaten before fully ripe when crispy, the pink eaten when
ripe. Seeds are numerous and small, hard and inedible in the white, softer and
edible in the pink. Flavor varies tremendously among cultivars.
Months for fruit to ripen:
3-5. Ripe when strongly fragrant and the rind softens
to be fully edible. Fruits ripen at various times, not all at once.
Will continue to ripen after being picked.
Storage after harvest:
3-5 days at room temperature if ripe.
Refrigerated without wrapping, after just ripening, up to 4 weeks.
Medium green, ovate to lance-shaped, stiff and thick, downy on underside,
aromatic when crushed.
No thorns. Bark is mottled reddish brown, peels off in flakes.
Commercially grown guava is usually grafted onto a specially
chosen rootstock. In regions where hard freezes may happen every few years, however,
non-grafted trees can come back from their roots after a freeze and are preferable for
residential owners. Pink-fleshed guava are reportedly more cold hardy than
white-fleshed varieties and will come back from roots quicker after a hard
freeze. Guava roots are shallow, often producing suckers.
Invasive in wet tropical regions such as Hawaii and Florida.
Cultivars of Note:
'Hawaiian Pink Supreme' Excellent flavor.
'Mexican Cream' Excellent flavor.
Attracts bees. Fruit attracts birds and mammals.
Toxic / Danger:
No. However, a chemical compound in the leaves acts as
a cardiac depressant and is contraindicated for some heart conditions.
Southern Mexico and Central America. Cultivated more than 2000 years.
