Of all the many and varied orchids, cymbidium orchids are the most popular because they are the easiest to grow. They are naturally terrestrial, so can be grown in the ground if the media (soil) is coarse and rich enough. (epiphytic orchids that naturally grow in crotches of trees want coarse bark in well drained pots.) They are also more tolerant of cool weather than tropical orchids are.
Plants with slightly yellowish leaves tend to bloom better. If the foliage is too dark green, it may not be getting enough sunlight. Regular application of fertilizer may promote bloom, although some plants do not seem to be too demanding. Watering may need to be as frequent as every three days through summer.
The arching flower stalks that begin to appear over winter may bloom for two months. They can be three feet tall, so stand well above the strap shaped leaves that get about two feet tall. Each stalk has many waxy flowers that can be two or three inches wide, in almost any color but blue. Most flowers are pastel hues of pink, lavender, yellow, orange, chartreuse, tan or white, and are intricately spotted and blotched.
