The favorite Chinese orchid of Holger Perner, who loves the waxy candy-pink flowers and appreciates the anti-inflammatory and soothing properties of the stems that can be chewed raw in case of a sore throat, at least if you don’t mind the bitter taste. Apart from being a home remedy this is a lovely orchid that can be grown mounted, in baskets or in well-drained pots. Flowers in spring.

Dendrobium crepidatum Lindl. & Paxton 1850

 

Common Name The Shoe-Lip Dendrobium [refers to the cavity at the base of the column foot] - In Chinese "Mei Gui Shi Hu" - In Thai "Ueang Sai Nam Khieo"

Flower Size 1 to 1.8" [2.5 to 4.6 cm]

Found from Hainan China, Assam, Bangladesh, eastern Himalayas, India, Nepal, Sikkim, western Himalayas, Myanmar, Thailand, Laos and Vietnam at elevations of 600 to 2100 meters as a small to medium sized, cool to warm growing epiphyte occuring on tree trunks as a suberect to pendant growing orchid that is best mounted on tree fern or cork. This species has tufted, suberect to pendulous, terete, striated, to 18" [to 45 cm] long, many noded stems each covered with a papery sheath, and carrying 5 to 9, oblong to narrowly lanceolate, acute leavesblooms in the spring on a short, purple inflorescence with the 1 to 4 shiny, waxy, delicately fragrant, longlasting flowers arising from near the apex of year old leafless stems. Drying out of the plant during the winter is nessasary with occasional waterings and no fertilizer until the initiation of new growth in the spring.

CULTIVATION TIPS:
Dendrobium aggregatum

 

Dendrobium aggregatum  is just one species of many in the genus Dendrobium: there are more than 1,000 species. Thus, the care and cultural requirements of Dendrobiums varies widely. This month's article will focus on the interesting species Dendrobium aggregatumwhich is also known as Dendrobium lindleyi.

Dendrobium aggregatum is one of the Callista species and is native to Burma, northern India and southern China. Other species in the Callista family include: Den. chrysotoxum, Den. densiflorum, Den. farmeri. These are classified as dwarf dendrobiums. They do not grow into tall canes but have short spindle-shaped pseudobulbs bearing thick, leathery leaves. These orchids like to be mounted on bark or cork. Dendrobium aggregatums are 'evergreen', which means they do not drop their leaves as some of the tall cane dendrobium orchids.

Care Tips: Dendrobium aggregatum definitely require a change in the cultural requirements at various times of the year and become dormant in the fall through winter months. They should be suspended and mounted on bark or cork for optimal growth. Grow them with your cattleyas (intermediate to warm conditions) but they require somewhat cooler temperatures during the winter months. In the winter move them to a cooler location and provide them with cooler night temperatures and dry conditions. Good air circulation is necessary.

Light: Dendrobium aggregatum takes high light, so keep them with cattleyas.

Watering: Watering is a crucial element for this orchid. (and may be the most difficult regimen to follow!) During spring and summer, water well when growth is developing. Be generous with your watering and fertilizing. As Autumn approaches, it is important to cut back on your watering and fertilizing schedule. Dendrobium aggregatums require dry conditions in the winter. During the fall and winter, water your plant only enough to keep the pseudobulbs from shriveling and dying. Be aware that the pseudobulbs will become wrinkly during this dormant period. You will need to learn the distinction between what is considered wrinkly and when the orchid will need some water to keep it from dying. Don't fertilize at this time. This severe drying and rest period is difficult to do especially if you are heavy handed with the water or if you are more accustomed to watering. But stick with it!

As Spring arrives and flower buds begin to emerge, increase your watering schedule. Water well while flowering and with the signs of new growth. As late Spring and Summer progress, increase watering and water thoroughly. If the tips of the leaves begin to brown, reassess how much fertilizer you are providing. Perhaps the concentration is too high and the leaves are experiencing some fertilizer burn. Or try changing your watering schedule. Determine how your orchids respond to any regimen you have established and be flexible to change if needed.

Flowers: Flowers usually appear Spring to Summer and is dependent upon adequate light. The Dendrobium aggregatum orchids form hanging clusters (like grapes) of yellow-orange flowers. The flowers are truly delightful. Flowers are approximately 1 inch in diameter, are flat with round lips. Flowers are delicate and cascade gracefully. Flowers last approximately 1-2 weeks.

Miscellaneous: Watch for spider mites. They love to live among the pseudobulbs. Spider mites are difficult to rid and will suck the life and energy out of the plant. If your plant takes a downward turn, begins to yellow, check carefully for any infestation.

Dendrobium aggregatum does necessitate a considerable change in their care in order to produce flowers. They need a solid rest period. Dendrobium aggregatum is a difficult orchid for a novice grower. It is truly difficult not to water! It took me two years to finally get it right! If it is not flowering for you, try something a little different: cooler temperatures, more light, less water. It does take time to master this species. Simply put, remember these tips: Spring to Fall give adequate amounts of water, fertilizer and light. Fall to winter give cooler temperatures (especially at night), water SPARINGLY to prevent them from drying out, keep on dry side.

Overwatering this orchid will only induce growth and will prevent it from flowering. This dormancy period is crucial. Sometimes the best advice one can give is just forget about your plant during these months of dormancy. You may think the plant has died and may be tempted to discard it. Be patient and diligent with their extreme care requirements and you will be rewarded with gorgeous inflorescences.

Good luck!

Dendrobium crepidatum Lindl.

Epiphyte. Stems long as 7 to 20 cm long and thickened around 1 cm at the base and 1 to 2 cm at its apex, green marked with parallel white lines, gradually going thickened upwards from the base, nodes slightly swollen, pendulous. Leaves 4 to 6 cm long, linear-lanceolate, deciduous during flowering. Flowers in short peduncles from the nodes of leafless stems, 2 cm across, often solitary but also seen with two or three together, fleshy, sepals and petals white with pale pink margins, sepals three and petals one veined; lip white with a large pale yellow spot of its middle portion. Sepals and petals broadly oblong. Lip obovate, broad, with undulate edges.

 

The Pursuit

The species got much attention of Sir George King and Robert Pantling during their monumental work. They found much variations in the property of the species from specimens collected from Sikkim and as well as from Assam and Khasia Hills. They described the Sikkim specimens as “unattractive” and those from the Assam and Khasia Hills as “rather handsome flowers”. I had earlier studied the same species from Assam and Khasia Hills in the year 2009 and 2010 respectively. I was so enthusiastic to find the difference of it from the specimens of the Sikkim-Himalayas and was there in the region in the early summer of 2012. In the earlier visits itself I had found this plant from various tropical valleys. Its thickened, fleshy, leafless, white veined, green, pendulous and leafless stems, 3 or 4 together can be spotted very easily from its habitats. However, the species bloomed much earlier than expected and I missed a “well planned” opportunity. Lost the hope in getting it in flowers that year and marked as “pending observation”. But in the middle of April, I was at an altitude of around 3000 ft on the other side of the district for some other species and I found the same one in bloom, a few of them in flower and in buds. Those opened flowers were somewhat withered and with spots and dirts. So I decided to wait a couple of days for the buds to bloom and got this perfect photograph with its yellow spot and fleshy property of the sepals and petals well recorded. On comparison with the evidences of the species from Assam and Khasia Hills, it has been found that the Sikkim-Himalayan specimens are comparatively smaller in size but equally attractive.

VENDORS

From marniturkel.com

The Species: This species is from Southeast Asia, India and China and is found at elevations from 2000 to 7000 feet. It is an epiphyte and has an arching to pendant growth habit. Summer monsoon rains are heavy as is the humidity with less rain in the winter. The flowers are produced on leafless canes which will produce flowers for many years. The flowers are long lasting and sweetly scented.

Culture: I have grown this species potted (and staked up the growths), but because of the somewhat pendant habit it is also grown mounted. Potted, use a relatively small pot and a fast draining mix. The summers are warm, shady with a lot of water and regular fertilizer. Winters are brighter, a bit cooler, and drier. Water to prevent severe shriveling. To prolong the life of the flowers, do not water plants during budding or blooming. After flowering and as new growth begins, increase water and fertilizer. I have grown this species in the intermediate to cool range, but I believe it will also do well warmer.
