A Mysterious Beauty from Thailand's Mountain Forests Hoya sp. Loei (also known as Hoya sp. SR 2007-13 from Loei Province) is a rare and still unnamed Hoya species from the montane forests of northeastern Thailand. This rare gem combines striking silver-splashed foliage with the promise of exceptionally fragrant flowers - a combination that has made it highly sought-after among Hoya enthusiasts worldwide. The long, slender leaves adorned with shimmering silver variegation create an immediately eye-catching display, while the plant's easy-growing nature makes it a joy for beginners and seasoned growers alike. Vermont Hoyas describes it as 'a great Hoya when grown for the foliage alone and even a better Hoya if you are looking for a flowering challenge.' For those who let it settle in and bloom, the reward is flowers of extraordinary fragrance. Origins & Discovery This species originates from Loei Province in northeastern Thailand, a region known for its mountainous terrain and cool-climate forests. GrowTropicals notes that it is 'likely found within montane evergreen forests such as Phu Kradueng or Phu Ruea National Parks at mid-elevation (around 1,000-1,300 m).' Phu Kradueng National Park, Thailand's second-oldest national park established in 1962, rises to 1,316 metres with a distinctive flat-topped plateau - an environment characterised by cool temperatures (average 15-20°C year-round, dropping to freezing in winter), high humidity, and diverse forest types from tropical to pine savannah. The plant was introduced to cultivation by Thai Hoya collector and hybridiser Surisa Somadee, whose accession number SR 2007-13 has become the plant's alternative designation. Vermont Hoyas notes: 'I emailed Ric Morier, and he told me that it was the number of Surisa Somadee in Thailand and this plant belonged in the Hoya acuta/verticillata complex.' The species remains officially undescribed and unnamed, adding to its mystique and allure for every plant lover. Foliage - Silver-Splashed & Elegant The foliage is the primary attraction of this species. Steve's Leaves describes the leaves as 'narrow elliptical with parallel venation and splashes of silver variegation.' Greenboog elaborates: 'long, slender leaves adorned with a mesmerizing splash variegation pattern that shimmers with hints of silver against a rich green backdrop.' Rare Hoya reports that 'adult leaves can reach 12-14 inches long' - an impressive size that makes established specimens truly spectacular. The leaves are thick and elongated, with prominent parallel veins creating texture against the green-and-silver colouration. The silver splash pattern varies between leaves and intensifies under proper lighting conditions, creating an ever-changing display. Gardino Nursery describes them simply as 'gorgeous long narrow leaves with some flecks.' Flowers - Rare But Extraordinarily Fragrant The flowers of Hoya sp. Loei are a special, uncommon treat - and magnificently rewarding when they appear. Vermont Hoyas chronicles a rewarding journey to flowering: 'After nearly five years it finally flowers... They say that patience is a virtue, but truth be told I had just about run out of it.' The flower description from Hoya 092122 states: 'a beautiful flower with a cream to light-green coloured corolla that reflexes completely with maturity. The corona of the flower is wide, upright, and white.' Steve's Leaves describes them as 'porcelain white flowers with orange and pink at the centres of the coronas.' The fragrance is the true reward - Vermont Hoyas reports: 'The flowers if you are lucky enough to ever see them are incredibly fragrant.' Unsolicited Plant Talks confirms: 'Although its blooms are rare, they are incredibly fragrant, making them well worth the wait.' Greenboog notes the flowers are 'typically white with a yellow or orange centre.' Growth Habit & Development Growth habit is trailing or climbing, making this species suitable for both hanging baskets and trellised displays. Steve's Leaves notes the 'trailing or twining growth habit.' Greenboog indicates the plant can reach 'up to 3m' in length. The plant is widely described as an easy grower that rewards the attention you give it. Unsolicited Plant Talks states: 'As an otherwise easy grower, this Hoya is highly recommended for both beginners and seasoned plant enthusiasts alike.' Vermont Hoyas confirms: 'It is an easy grower that I can highly recommend!' It is wonderfully easy to keep alive and thriving - only its blooms ask for a little patience, and the foliage alone makes cultivation worthwhile. Care Requirements: Light: Bright, indirect light is essential. GrowTropicals advises: 'Provide bright, indirect light or dappled shade. Avoid direct sun, even morning sun, as it may scorch the leaves and reduce the silver pattern contrast.' Unsolicited Plant Talks recommends to 'recreate a dense forest environment' with 'very little, if any, direct sunlight.' The silver splash pattern is most vibrant under adequat
