Ugni molinae – Chilean Guava
Ugni molinae, commonly known as Chilean Guava or strawberry myrtle, is a shrub species from the myrtle family (Myrtaceae) native to Chile and adjacent regions of southern Argentina. The botanical name comes from the Mapuche word "uñi," which the indigenous people used to refer to this plant. The species was first scientifically described in 1782 by Juan Ignacio Molina, whose surname is the source of the species name.
Chilean Guava is an evergreen shrub belonging to the same botanical family as the true guava, although they are distantly related species. The plant was introduced to England in 1844 by botanist William Lobb and quickly gained popularity, becoming a favorite fruit of Queen Victoria. Today it is cultivated as an ornamental and fruit plant in mild climate regions worldwide.
Botanical description and plant appearance
Ugni molinae forms a dense, compact shrub ranging from 30 cm to 170 cm in height, rarely reaching up to 3 meters. It features evergreen foliage composed of small, leathery leaves shaped elliptically or lanceolate. The leaves are 1-2.5 cm long and about 1-1.5 cm wide, entire, dark green and glossy, and when crushed, they emit a distinctive spicy-fruity aroma.
The flowers are solitary, pendulous, about 1 cm in diameter, with four or five white or pale pink petals and numerous short stamens. They appear in leaf axils and have a bell shape. After pollination, small, spherical fruits develop – berries 6-15 mm in diameter, initially green, then red, and when fully ripe, dark red to purple. The fruits have an intense aroma reminiscent of wild strawberries with a spicy note.
The shoots are delicate, becoming woody over time and often showing fine hairiness. The plant grows relatively slowly, forming over the years a dense, rounded crown with high ornamental value throughout the year.
Biological cycle and special features
Ugni molinae blooms in late spring and early summer, usually from May to July in temperate climate zones. The plant is self-compatible, meaning it can self-pollinate and does not require the presence of other individuals to bear fruit. The fruits ripen gradually from August to October, reaching full maturity in autumn.
One of the characteristic features of this species is the intense aroma of its leaves and fruits. The leaves release essential oils with a spicy-fruity scent when crushed, and the ripe fruits smell strongly of strawberries. In natural conditions, the plant grows in temperate rainforest understories. It is highly resistant to fungal diseases, including the serious honey fungus disease.
Temperature tolerance
Ugni molinae shows moderate frost resistance, tolerating temperatures down to about -10°C during full winter dormancy. Young spring shoots may be damaged by late frosts, so in regions with harsher climates, the plant requires shelter or cultivation in a cool room during winter. In Mediterranean climate zones and areas with mild winters, it can be grown outdoors year-round.
The optimal temperature for growth and development is 15-25°C. During the growing season, the plant tolerates temperature fluctuations well but needs protection from strong winds and excessive sunlight during the hottest parts of the day.
Plant uses
Chilean Guava has a wide range of uses both as an ornamental and a functional plant. Thanks to its attractive appearance year-round – glossy leaves, delicate flowers, and colorful fruits – it is valued in gardens as a solitary shrub or a compositional element. It is excellent for creating low hedges, container cultivation, and as a plant for rock gardens.
The fruits are edible and very aromatic, with a flavor reminiscent of wild strawberries with a hint of pineapple and a subtle spicy note. In Chile, they are used to produce the traditional Murtado liqueur as well as jams and desserts. The leaves can be used as a tea substitute, and roasted seeds as a coffee substitute. In the food industry, the fruits are a source of natural strawberry flavor.
Who is this species for
Ugni molinae is ideal for lovers of exotic fruit species and those seeking attractive ornamental shrubs with low requirements. It is especially recommended for gardeners in mild climate regions who want to grow unusual functional plants. Due to its slow growth and compact size, it is perfect for small gardens and container cultivation.
Summary
Ugni molinae is a unique species combining ornamental qualities with practical use. Its evergreen leaves, aromatic flowers, and edible fruits make it a valuable addition to any garden in temperate climate zones. Although it requires frost protection in cooler regions, its beauty and uniqueness make it worth cultivating. It is a plant for those who appreciate uniqueness and want to enrich their garden with a species that has a rich history and wide culinary use.
