Syzygium jambos
pomarosa, pumagas, manzana rosa, malabar plum, plum rose, rose apple
The Malabar plum is a large tree that can reach a height of up to 20 meters. The flowers are large, white or cream-colored, and look like pompoms. The fruit is subglobulose and is 2-4cm long, with a whitish to pinkish-yellow color. Malabar plum trees sprout vigorously when cut.

The plants may bloom and produce fruit within 3 to 4 years old. Rose apple trees sprout vigorously when cut.

Taxon category: Accepted
Syn.: Eugenia jambos L. fide Royal Botanic Gardens, Kew & Missouri Botanical Garden (2010)
Origin: Introduced - established
Year of first record: 1965
Mode of introduction: Intentional
Introduction Pathway: Intentional
Subpathway: Agriculture/Horticulture
Introduced status: Naturalized
Invasive status: Invasive
Impact in Galapagos: It has invaded large areas of agricultural area and the National Park in San Cristobal, where its dense canopy shades the understory and inhibits the growth of other plants.
Impact elsewhere: The tree is able to invade all types of forests including natural forest, it has the potential to invade riparian vegetation and colonize the edges of wet rainforests of the tropics and subtropics. This species has formed nearly monospecific patches of high density and height in places without human disturbance. Its dense canopy heavily shades the understory, inhibiting the growth of other plants.
Control History in Galapagos: On Floreana, there are very few plants and there was a program to eradicate the species from the island. The project is missing monitoring.
Control methods elsewhere: The seedlings should be pulled manually. For trees, use herbicide applied to cuts made in the trunks (girdling).
Known Pest elsewhere: Widespread
Preference for an altitude zone in Galapagos: Humid zone
Habitat preferences: Malabar plum trees thrive in moisture-rich zones and survive in variety of different soil types. Malabar plum trees invade undisturbed forests.
Trophic role: Primary producer
Reproductive biology: The malabar plum may bloom and produce fruit within 3 to 4 years old.
Growth form: Trees
Distribution origin: Southeast Asia
Distribution classification: Paleo-tropical
Map of specimen collection localities or observation records for this species in our collections database.
Distribution: Santa Cruz, San Cristobal, Floreana, Isabela, originally from Southeast Asia. The distribution is wide on San Cristobal but on Santa Cruz, Floreana, and Isabela it is primarily found in the agricultural zone and near towns.
