Happy equinox! Welcome to the first day of spring, unless you’re in the southern half of the planet. In that case, welcome to the first day of autumn. No matter where you are on earth, day and night last 12 hours each. Like all plants, orchids detect the lengthening days and increasing strength of the […]

Unlike most commonly cultivated varieties, it’s a terrestrial, meaning that it grows in soil. This orchid is native to a large area of south Asia, stretching from India through […]
While the rest of the country has been frozen, California is having a winter heatwave. Yesterday San Francisco set a new record high for the date at 74F (23C,) and there may be another record high today.

Cochlioda vulcanica is frequently used in hybridization, cross-bred with orchid relatives to pass on both its hardiness and its beauty.

To grow these beauties with their sweet, richly scented flowers, you need to provide […]
Like all plants, orchids need a healthy root system to survive and thrive. At least once a year, orchids enter a growth cycle when they generate new roots. These new roots are light green at the tips, and turn white with time. As they age over several months, they may turn brown. Since orchids are […]
Moth orchids, or Phalaenopsis, love warm temperatures. But one trick used by orchid experts is to give Phals a few weeks of cool nights in the fall.
