The structure of the leaves corresponds to the specific habitat of the plant. Species that typically bask in sunlight, or grow on sites which can be occasionally very dry, have thick, leathery leaves and the laminae are covered by a waxy cuticle to retain their necessary water supply. Shade-loving species, on the other hand, have long, thin leaves.
Hi. I have a moth orchid that was in bloom when I got it, five years ago. After the blooms dropped off, the flower stock dried out and I cut it off (thought I was supposed to) and it hasn't bloomed since. I thought it would grow a new stock and bloom again the next year. But it hasn't. I'm not experienced with orchids, so am guessing I did the wrong thing by cutting off the stock. Can you give me some direction on this? Is this plant likely to every bloom again? Thank you for any help you can provide.
Do a finger test. This is the best way to determine whether an orchid needs more water. Stick your pinky finger into the potting mix, taking care not to disturb the orchid's roots. If you don't feel any moisture, or you feel just a little, it's time to water the orchid. If you feel moist potting mix right away, give it more time. When in doubt, you should wait an extra day.
This type of orchid has over 200 species and has a star-shaped appearance. Most of them have small- to medium-sized blooms and come in colors such as yellow, white, or light green, although most of them are white. The flower has a wonderful fragrance, needs even amounts of water, and prefers temperatures between 60 and 80 degrees Fahrenheit, mainly because they are not a bulb plant and therefore cannot store water. They also look beautiful in hanging baskets and pots.
The Gongora orchid genus is a really neat type of orchids, related to Stanhopea. They have nice, strong fragrances, often of cinnamon, allspice, or nutmeg. The flower stems hang over the pot's edge and the flowers point downwards. They can adapt to a wide variety of lighting conditions and a relatively large temperature range, but like a lot of water.
Some people have very responsibly done research before watering their plant and are confused by recommendations they’ve found elsewhere that say to use only water at room temperature. Here at Just Add Ice Orchids, we love orchids and have tested our theory before offering it to others. We’ve found that those who follow our recommendation meet with orchid success!
Pollinators are often visually attracted by the shape and colours of the labellum. However, some Bulbophyllum species attract male fruit flies (Bactrocera spp.) solely via a floral chemical which simultaneously acts as a floral reward (e.g. methyl eugenol, raspberry ketone, or zingerone) to perform pollination. The flowers may produce attractive odours. Although absent in most species, nectar may be produced in a spur of the labellum (8 in the illustration above), or on the point of the sepals, or in the septa of the ovary, the most typical position amongst the Asparagales.
The seeds are generally almost microscopic and very numerous, in some species over a million per capsule. After ripening, they blow off like dust particles or spores. They lack endosperm and must enter symbiotic relationships with various mycorrhizal basidiomyceteous fungi that provide them the necessary nutrients to germinate, so all orchid species are mycoheterotrophic during germination and reliant upon fungi to complete their lifecycles.
A pollinium is a waxy mass of pollen grains held together by the glue-like alkaloid viscin, containing both cellulosic strands and mucopolysaccharides. Each pollinium is connected to a filament which can take the form of a caudicle, as in Dactylorhiza or Habenaria, or a stipe, as in Vanda. Caudicles or stipes hold the pollinia to the viscidium, a sticky pad which sticks the pollinia to the body of pollinators.
Orchids of all types have also often been sought by collectors of both species and hybrids. Many hundreds of societies and clubs worldwide have been established. These can be small, local clubs, or larger, national organisations such as the American Orchid Society. Both serve to encourage cultivation and collection of orchids, but some go further by concentrating on conservation or research.
