Camellia chrysantha macrophylla S.L.Mo & S.Z.Huang
Camellia euphlebia is an evergreen shrub or a small tree; it can grow 2 - 5 metres tall[
This is one of several species of Camellia growing in Guangxi that have golden-yellow petals. These petals are being harvested indiscriminately from several of those species for purported medicinal benefits.
Camellia euphlebia has a restricted range, being found in northern Vietnam and one location in Guangxi, China. There are constant threats of cutting or habitat clearance. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2013)[
E. Asia - southern China (Guangxi), northern Vietnam
Evergreen broad-leaved forests along streams; at elevations from 100 - 500 metres[
Camellia species are found mainly in the warm temperate to subtropical regions of southern China, and most species experience mild winters with few frosts plus wet summers[
]. Camellia euphlebia is found mainly at low elevations in southern China, and will only succeed outdoors in the very mildest regions of the temperate zone.
Species in this genus generally prefer a peaty, more or less lime-free soil with a pH in the range 5 - 7, but most will grow well in an open loam to which ample leaf-mould has been added, so long as it is well-drained and lime-free. Most species are understorey plants in forests (preferably oak or pine) and prefer a warm, sheltered position with moderate shade; at least at the hottest time of day[
]. Requires a position sheltered from strong winds[
The seeds of Camellia species are generally rich in oil and many are harvested from the wild and/or cultivated for their oil. We have no specific information for this species[
The oblate capsule is 20 - 30mm x 35 - 60mm, 3-loculed with 1 or 2 brown, globose seeds 15 - 20mm in diameter per locule[
The petals are fleshy and golden-yellow in colour[
]. We have no specific information for this species, but since 2010, companies in Guangxi have been promoting yellow Camellia flowers as a medicinal product. It has been reported that a kilogram of of dried wild yellow Camellia flowers is priced at more than 10,000 yuan ($1,607), and consequently the golden-yellow petals of most, if not all, Camellia species in Guangxi are being harvested indiscriminately[
Seed - can be sown as soon as it is ripe in a greenhouse[
]. Stored seed should be pre-soaked for 24 hours in warm water and the hard covering around the micropyle should be filed down to leave a thin covering[
]. It usually germinates in 1 - 3 months at 23°c[
]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for at least their first winter. Plant them out into their permanent positions when they are more than 15cm tall and give them some protection from winter cold for their first year or three outdoors[
Cuttings of almost ripe wood, 10 - 15cm with a heel, mid summer to early autumn in a shaded frame. High percentage but slow[
Cuttings of firm wood, 7 - 10cm with a heel, end of early summer in a frame[
]. Keep in a cool greenhouse for the first year[
Leaf-bud cuttings, mid summer in a frame.
