Uvaria grandiflora, commonly called large-flowered uvaria or kawilan, is a climbing shrub in the Annonaceae. The accepted species is recorded in the current GBIF taxonomic backbone.[1][2] It is a tropical fruit plant with separate fleshy carpels rather than a single solid berry.
Description[edit | edit source]
The plant is described as a sturdy climbing shrub with stems reported up to about 10 m.[3] A compiled account places it in southern China at about 400–1,000 m; that elevation range is habitat context, not a tested hardiness limit.[3]
The fruit is made up of distinct, cylindrical, fleshy carpels. They are described as orange and about 4–5.5 cm long, with an aromatic character.[3] A separate catalogue also illustrates the plant's flowers and fruit, but its horticultural statements do not disclose trial conditions.[4]
Cultivation[edit | edit source]
Soil and water[edit | edit source]
The plant's recorded habitat and climbing growth indicate that a deep root zone and a support structure are sensible establishment priorities. The accessible horticultural guidance lists regular-to-moderate watering; use that as a cautious starting point in a freely draining medium, adjusting for temperature, light and drying rate rather than following a fixed calendar.[4]
Avoid treating the southern-China elevation record as a soil or irrigation prescription. In a container, use a stable trellis and enough volume for the climbing root system; container suitability is listed by the horticultural catalogue, but no container size or long-term trial is given.[4]
Sun and humidity[edit | edit source]
Bright light to full sun, with semi-shade available during the strongest exposure, is the cautious starting point listed for cultivation.[4] The plant's native tropical setting supports maintaining warm, humid air and good airflow; use the plant's response rather than a fixed humidity threshold. Give the climber a support that keeps foliage from lying against persistently wet surfaces.
Seasonal changes[edit | edit source]
Frost is a protection trigger: the horticultural account describes the plant as frost-sensitive, but does not establish a hardiness zone or minimum temperature.[4] Keep the root zone from swinging between prolonged saturation and severe drying during warm growth, and reduce watering when cool, dim conditions slow transpiration. The appropriate seasonal response is therefore protection from cold and adjustment to actual drying, not a universal month-by-month schedule.
Propagation[edit | edit source]
Seed propagation is the documented route for this species, although no pre-treatment or sowing schedule is specified in the available plant account.[3] A dated observation from Dokmai Garden in Chiang Mai, Thailand, records failed vegetative propagation on one cultivated plant; that result belongs to the reported plant and method, and is not a general claim that every cutting or other vegetative method will fail.[5]
Flowering, fruiting, and harvest[edit | edit source]
The large flowers are a notable feature: a 2011 observation at Dokmai Garden described them as palm-sized.[5] The same cultivated plant produced fruit that was ripening at the time of the report. This confirms fruiting under that Chiang Mai garden's conditions, but does not establish a bearing age, yield, pollination requirement or universal season.[5]
Harvest should be guided by the fruit's visible ripening on the individual plant. The supplied descriptions identify the carpels and their orange color, but do not provide a validated harvest index or storage-life measurement.[3]
Fruit and uses[edit | edit source]
The carpels are described as aromatic and edible raw or preserved in a Southeast Asian plant-use account.[3] The catalogue repeats the raw and preserved uses.[4] These records document reported use; they are not a modern food-safety assessment, and no medicinal or nutritional claim is made here.
