Mother’s Day is next Sunday so the Kona Orchid Show and Sale is a great opportunity to find the right gift for that special lady. The annual sale will be held at the Old Kona Airport Park Pavilion on Saturday, May 13.
Orchid growers from around the island will bring new and exotic orchids seldom available at other times. Local crafters will be there with pottery, ceramics, real flower jewelry and nurturing gemstones. There will also be an abundance of fruit trees and other garden plants.
For more information on the sale and program you may call Bob Zeller at 333-0889 or email him at orchidbob1@gmail.com.
At one time, the island of Hawaii was known as the Orchid Isle due to the commercial production of Vanda and Dendrobium orchids. Wild bamboo orchids and Malayan ground orchids grew and still grow prolifically in open meadows. The understory of mauka forests to this day are filled with Phaius tankervilleae or Chinese ground orchids. Fancy varieties of these naturalized species are now being grown by orchid enthusiasts.
There are many orchid species and hybrids that are easy to grow in Hawaii. Orchids are well adapted here and many species need almost no care. Epidendrum radicans, along with the new Epi-cats (Epidendrum and Cattleya), with their attractive pastel shades are becoming quite popular as houseplants and outdoor plantings. Epidendrums produce thin, reed-like foliage with many aerial roots. Tip cuttings with a few serial roots may be potted to increase the numbers of this plant. Flowers are one inch or less in size but are produced in great numbers. They are very effective for arrangements as well as for corsages.
Oncidiums are among the most valuable of the spray orchids. They are commonly referred to as dancing girls or popcorn orchids because of their shape. Flowers come in yellow and brown, white and brown, and other similar color combinations. They may attain sizes of 1/2 to 3 inches across. Many flowers may be produced on a single flower spike.
Strap-leafed Vandas have become very popular with growers and hobbyists. The wide range of colors, from blue to brown to whites, have attributed greatly to its popularity. Vanda flowers are long lasting and excellent for corsages. Each flower spike will produce many flowers, several inches or more in diameter. Plants are excellent for hanging baskets containing only charcoal, but will need fertilizer applications.
For the more advanced gardener, try the butterfly orchid or Phalaenopsis. It is desirable for corsage use. Flower spikes will contain from a few to many flowers. Lavender or white flowers are most common. Flowers will average about two inches across and will remain open for several weeks.
For high-elevation gardeners, try the Cymbidiums. Cymbidium is an exciting genus with hybrids flowering in a wide range of colors including pink, red, yellow, green, maroon, bronze, and white, in bold vibrant tones as well as more delicate pastels and art shades. Their tall, erect, arching, or hanging sprays, durability and longevity, ease of cultivation, and usefulness as a potted plant, landscape plant, or commercial cut flower have led to tremendous worldwide popularity. Conventional varieties require cool evening temperatures of about 55 degrees F during the late fall and winter months for good flowering to take place. Such conditions occur naturally in Volcano, Kamuela and upper Kona on the Island of Hawaii, Kula on Maui, Kalae on Molokai, Pupukea on Oahu, Waimea on Kauai, and other scattered areas, mostly above 1500 feet elevation, around the state.
The species and hybrids of miniature Cymbidiums require basically the same growing conditions as the larger conventional types. A major cultural difference is that most of the miniatures do not require temperatures nearly so cool as their larger relatives. The preferred temperature range for “minis” is 70 to 80 degrees F during the day followed by a 10 degree drop at night, a condition much easier to achieve in Hawaii’s lowland areas than that required by the conventional types.
You can minimize orchid care by attaching orchids to a tree like plumeria or calabash, That way you can have dozens of blooming orchids even in a small garden. Other epiphytes like staghorn ferns, bromeliads and some Vireya rhododendrons may be incorporated to create air gardens. There are also many species of epiphytic cactus available for your garden in the trees.
Many more rare and interesting species will be available for Mother’s Day gifts along with expert orchid enthusiast to answer your gardening questions.
