Aerangis hariotiana blooms in the late winter to early spring (northern hemisphere) with numerous racemes of densely packed sherbet-orange, strongly night-scented, miniature flowers.
A small, usually pendulous, monopodial epiphyte that is almost stemless. The short stem is hidden by the basal sheaths of closely set leaves. The roots are often flattened, with thin velamen, are green when wet, and have emerald green tips. Aerangis luteo-alba var. rhodosticta has yellowish white flowers with a bright orange-red column.
Cultivated plants should be kept moist during periods corresponding to the wet seasons. They should be allowed to dry slightly between waterings during the dry seasons, but should never dry out completely or be left dry for extended periods.
This species is a large to giant sized, highly variable, hot to cool growing epiphyte. Like related genera, Aerides are best grown in open slatted baskets. Aerides species require ample water, every day in warm climates. 70626r higher relative humidity is beneficial although the plants can be grown lower. They require bright filtered light with some direct sunlight in the morning, semi-shade area placement is perfect.
It is a good orchid to put into a meadow or wildflower lawn and usually thrives. Flowering takes place in late June through July. It also grows happily in a cold greenhouse, preferably in a plunged terracotta pot.
Tulip Orchids are rather large terrestrial and sometimes epiphytic plants with fleshy pseudobulbs longer than 20 cm. The long, lanceolate and plicate leaves of a full-grown Anguloa can be more than 1 m long. Two to four leaves grow from the base of each pseudobulb. The leaves are deciduous, and are shed at the start of each new growth.
The flowers of these orchids have a strong scent of cinnamon.
Anguloa clowesii grows in the mountains with very moist conditions at the roots. There is a dry season, and this coincides with the dropping of their deciduous leaves. The flowers emerge at the base of the newest growths in late winter to early summer.
Anguloa virginalis is a Anguloa endemic to Colombia.
The flower head can be up to 40cm long, consisting of many small mauve flowers in terminal racemes.
Orchids do not like to sit in wet or damp potting mix so water weekly during the warmer months and allow the water to fully drain.
The bamboo orchid, Arundina graminifolia, is a species of orchid and the sole accepted species of the genus Arundina. This tropical Asiatic genus extends from India, Sri Lanka, Nepal, Thailand, Vietnam, the Ryukyu Islands, Malaysia, Singapore, China to Indonesia, the Philippines and New Guinea. It has become naturalized in Reunion, Fiji, French Polynesia, Micronesia, the West Indies, Costa Rica, Panama and Hawaii.
Arundina graminifolia is a terrestrial, perennial orchid with reedy stems, forming into large clumps. This orchid blooms in summer and autumn, showing rather open clusters of showy terminal flowers, ten at the most. They bloom in succession on the terminal racemes. These flowers are a rosy lilac and white disk with a purple lip. The bracts are wide triangular and surround the main stalk of the flower cluster. The occasional fertilized seed pods contain minute powdery seeds, and small plants often develop near the cane ends after flowering, and likely aid in propagation if allowed to reach the soil.
With only 200 of the plant to be recorded growing naturally in Singapore, the species is close to extinction there, largely caused by the destruction of its natural habitat, namely the rainforests and mangrove forests. The remaining plants, commonly called Tapah weeds, can be found in the secondary forests or at the forest fringes. It is however very common in road cuts and other disturbed areas in full sun in Sarawak, East Malaysia, where it often is the most common flowering plant to be seen along the roadsides.
Bamboo Orchid produces pinkish flowers at the top of tall cane-like pseudobulbs. It's the only species in the genus. The plants are quite tall; they'll reach at least hip level, possibly over your head, and their vegetative resemblance to bamboo can be uncanny. The long pseudobulbs have leaves alternating along their length, similar to Epidendrum orchids. The flower stems, which emerge from the top of the canes, produce several flowers sequentially, so that there will be one at a time over an extended period. The flowers are white with a purple-to-pink lip, and shaped similarly to a Cattleya orchid flower. They are 2-3 inches across, and can appear for much of the year, especially in summer.
Arundinas readily propagate themselves by keikis, which frequently develop along the pseudobulbs. Once a keiki has roots a couple inches long (several cm), you can carefully cut it off and pot it separately. The canes do not grow rigidly upright, they'll sometimes tip over; in nature, this allows the keikis to get established nearby, so it's a major vegetative propagation strategy for these plants; it helps them rapidly grow into large clumps. These plants like colonizing disturbed habitats, often growing as roadside weeds in much of Southeast Asia; being able to grow quickly helps them succeed in such places.
These plants are tough: they are quite robust and forgiving of less-than-attentive care. They are terrestrial orchids, so they like a denser potting mix than most orchids. It should still drain freely, however, and not be as dense as soil. A good starting point is equal parts sand, sphagnum moss, and fine fir bark. Bamboo orchids should be watered as they approach dryness; don't let them dry out too thoroughly. If you grow them outdoors, either if you live in a warm climate or if you just brought it outdoors for the summer, rainfall might water it often enough in some areas; but if it's starting to dry out water it thoroughly. If you grow orchids indoors, these plants are often too big to take to the sink; the easiest way to water will often be to dunk the pot in a bucket, then pull it out. Any aerial roots, such as on keikis, should be misted regularly. Fertilize regularly; the usual recommendation is to use a fertilizer especially formulated for orchids feeding weakly. Most orchid fertilizers are designed to be dissolved in the plant's water. They like high light: 2000-3000 footcandles is ideal, similar to the low end of Cattleya lighting. In nature, they commonly grow in direct sunlight. As long as the lighting isn't too dim you're probably fine. If it doesn't bloom, try increasing the lighting. You'll get the best results growing them at warm temperatures. It's OK if the temperature varies more widely than this; they can actually withstand mild freezes occasionally, though it's quite stressful for them. Any temperature that's reasonably comfortable (or a bit hot and muggy) for humans is going to be fine for bamboo orchids. They like good humidity, perhaps 70%, though this isn't critical. If the humidity is low, the plant should be misted regularly, especially if it has any keikis.

Ascocentrum orchids are beautiful Vanda relatives. They are generally considered miniature orchids, as they look a lot like Vandas, except smaller and brightly colored, with quite dense, erect flower stems. They are often hybridized with Vandas; the hybrids genus is called Ascocenda.
Water regularly and maintain high humidity and good air circulation.
With the publication of Genera Orchidacearum volume 6, all Ascocentrum species are now included in the genus Vanda.
Moderate water is required during the growing season. Care should be taken to keep water off the leaves of new growths.
Very nice plant with dark burgundy flowers.Terrestrial, requiring a rich sandy soil and leafmould media with good drainage and maximum sunlight.
