I DON’T REALLY need to say more than that. Killer cut flower: the Cymbidium orchid. By February, when winter gets tiresome, I pace myself the rest of the way to full-on garden season by buying a stem or two of these extravagant (though not expensive) orchids each month. They last many weeks in water; each stem is a few feet long with dozens of blooms, a bouquet in itself for about $10. I prefer the gaudy gold-and-wine ones to the pastels, but I never claimed to be discreet. Want to see more, or try growing them?
