Psidium cattleianum, commonly known as strawberry guava, Cattley guava or cherry guava, is a small tree in the Myrtaceae (myrtle) family. The species is named in honor of English horticulturist William Cattley. The plant is native to south-east Brazil, but has been naturalized in Florida, Hawai’i, tropical Polynesia, Norfolk Island and Mauritius. Its genus name Psidium comes from the Latin psidion, or “armlet.” The red-fruited variety, P. cattleyanum var. cattleyanum, is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava.[2] The yellow-fruited variety, P. cattleyanum var. littorale is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava, lemon guava and in Hawaii as waiawī. Although P. cattleyanum has select economic uses, it is considered the most invasive plant in Hawaii.

The strawberry guava fruit is very similar to the normal guava (scientific name P. guava) but usually considered to be more attractive but smaller in size. Some of the popular common names of the plant are Cattley guava, Chinese cherry guava, Chinese guava, cherry guava, purple guava, purple strawberry guava, red strawberry guava, small guava, strawberry guava, yellow Cattley guava, yellow strawberry guava, Peruvian guava, Thai Guava, Kuahpa, Bella seebai, Konda jamipandu, Malam perakka, Mpera-ngombe, Mpera, Pahadi pijuli, Pahari payara, Porpay, Quwawa ni vavalagi and Seemai koyya. Strawberry guavas are delicious when consumed fresh, with an attractive sour taste caused by the very high content of vitamin C. Cherry guava can also be prepared in many ways, into jelly, jam, ice cream, sorbet or juice. Boiling the fruit in water with added sugar produces a paste that is useful in bakery products as a filling.

Plant Description

Strawberry Cherry is small erect, highly-branched, slow growing evergreen shrub that grows about 2-6 m tall. The plant is normally found growing in sub-montane rainforest, montane cloud forest, montane rainforest, moist tropical montane forest, riparian forest, tropical evergreen forest, deciduous woodland (oak), tropical montane savanna, lowland sub-tropical rainforest, scrubland, grassland, degraded forest, cultivation and agroforestry systems, roadsides, wastelands, pastures, scrubs, forested land and on areas disturbed by natural processes such as storms and lava flows. The plant prefers acid soils and is not sensitive to soil structure. It can grow on shallow or infertile soils. It does, however, requires a well-drained soil and does not tolerate waterlogging. The slender stem and branches are smooth, pinkish, greenish or greyish brown in color. Bark peels off in small papery flakes. Twigs are glabrous and cylindrical, and young leaves and twigs are red in color.

Leaves

Leaves are opposite and decussate, shortly petiolate (petiole 3–10 mm long), elliptic to obovate, 4.5–12 cm long and 2–6 cm wide, with a blunt to slightly acuminate apex and a cuneiform sharp base. They are thick and coriaceous, upper surface is dark green in color, glossy, waxy, flat or slightly folded around the main rib. The lower surface is glabrous, whitish-green in color, punctuated with small oil cavities, and with the main rib prominent near the base but the 8–10 pairs of lateral ribs is not prominent, forming an intra-marginal rib 1–3 mm from the edge of the limb. Young leaves and twigs are red in color.

Flower

The fragrant flowers are axillary and solitary, rarely grouped in 2 or 3. The four to five white petals are obovate, 5–6 mm long and wide. Flowers bear numerous stamens, 256 to 480 according to Raseira and Raseira, and a greenish disc-shaped stigma. Ovary is tri- to penta-locular, mostly tetra-locular. Flowering normally takes place from May.

Fruit

Fertile flowers are followed by globulous to obovoid berry, 1.5–4 cm in diameter, bearing persistent sepals at the apex. The thin skin is dark green when unripe, and then red to purple for P. cattleianum var. cattleianum and sulfur-yellow for P. cattleianum var. lucidum. Pulp is soft, white or yellow, very juicy and contains several (2–100) small soft seeds. Seeds are reniform, 2–3 mm long, with a yellowish testa. Fruit has a pleasant, strawberry-like flavor when ripe, hence its common name.

How to Consume Strawberry Guavas

You can just bite it and consume it as it is small in size. In case you want to cut it, you have to first remove the calyx, or the protrusion near the bottom of the fruits that looks like a crown. Now wash it well cut it and consume it.  You may also peel off the skin and a layer of flesh so that the sweet pulp and seeds are left. Now boil the pulp with water for 30 minutes. For every pound of flesh, you can take about 4 cups of water. Cool it and then strain it to remove the seeds. Now boil the pulpy concoction again and add about 2 cups of sugar to it. Stir it till the pulp becomes thick and slightly creamy. You can use this as jam also.

Prevention and Control

Prevention

P. cattleianum is one of the five most important offensive plants on Reunion, and is also one of the most important invasive species on other Indian Ocean island Mauritius and the Seychelles, also in in the Pacific Ocean on Hawaii, USA, and French Polynesia. It is also on the Pest Plant List of the Florida EPPC, the HEAR Alien Species Map Index and on the Noxious Weeds List in Australia. For these reasons it is on the IUCN ISSG list as one of the 100 World’s worst invaders. Considering its serious invasive potential, further introduction of this species as an ornamental or fruit tree to tropical areas should be prevented where possible, and especially threatened areas and islands such as eastern Polynesia should be closely monitored.

Control

P. cattleianum is a difficult species to control and there is no effective control practice for large invaded areas. The control of naturalized populations must be approached with different techniques selected in the light of the specific circumstances in each case.

Cultural control

P. cattleianum is not subjected to a cultural control as it attacks mainly non-agricultural areas. In pastures, it is not browsed by cattle.

Mechanical control

Except for young seedlings, hand pulling is not possible due to the strong root system and the presence of suckers. Mechanical cutting of the stem leads to the development of abundant suckers from the stump and any mechanical control must be related with chemical control to avoid re-sprouting.

Chemical control

P. cattleianum is resistant to many foliar-applied herbicides. It is also resistant to 2,4D, and picloram applied as granules on the soil or applied on the cut stump mixed with diesel oil gave less than 50% success, but picloram activity and absorption by P. cattleianum leaves is increased by ammonium sulphate. P. cattleianum is, however, sensitive to glyphosate, triclopyr and tebuthiuron. Good chemical control has been obtained with undiluted triclopyr amine, with undiluted triclopyr ester or undiluted glyphosate on cut stumps, or with tebuthiuron Motooka et al., 1983, 1989; Santos et al., 1989). Triclopyr is recommended because of its lack of mobility and relatively short half-life. However these treatments are labor-intensive and can be applied only on limited areas.

Biological control

No biological control agents have been released to date. Research has concentrated on the identification of potential biological control agents specific to P. cattleianum in its native range. Two Hymenoptera, a species of Eurytoma and Haplostegusepimelas, lay eggs on growing twigs and affect plant growth and flowering and appear to be species-specific, which is an essential requisite to protect the congeneric common guava and native Myrtaceae species. Recently, a further species Tectococcus ovatus has proven to be specific to P. cattleianum and is considered suitable for release as a classical biological agent in Florida, USA.

Integrated Control

As wild pigs are effective dispersal agents in Hawaii, their control appeared to be the first step to control the spread of P. cattleianum. However, Huenneke and Vitousek put into perspective the role of pigs in germination and establishment and moreover, the control of pigs may be ineffective as birds and other mammals also disperse P. cattleianum seeds.

Other facts

  • The plant is grown as a hedge in warm temperate climates.
  • Leaves are also a source of essential oils produced after distillation.
  • The wood is useful for poles.
  • After 3 to 6 years of life, the plant starts to produce fruits.
  • The wood is good for smoking meat and can also be made into tools and toys.
