Stanhopea wardii

Dear Orchid Friends:

I consider Stanhopeas to be 'The Autumn' orchids. Their unique shape, fall colors and markings define the autumn months.

These orchids are tropical/subtropical growers. Stanhopea are found from South America to Mexico. Since these orchids thrive in tropical to subtropical environments, they like warmer temperatures, moisture and humidity. These orchids do not fare well in clay pots. Place them in wire or wooden baskets packed with sphagnum moss of osmunda fibers, or mount on bark. Roots like to be damp. An environment that is too dry is not well tolerated. Stanhopea have ovoid pseudobulbs with long grooved or pleated leaves.

There are a variety of species; the type of species determines the shape of the lip. The interesting lip formation is to enhance pollination, luring bees and insects. The unusual flower is the lure of this orchid. Sepals flare backwards towards the stem and have a hooked lip. The pendant spikes bear several flowers. Flowers are pendulous, poking through the medium if in baskets. Flowers are waxy and come in varying hues of cream and yellow with dark markings. Stanhopea wardii (pictured above, not completely open) is yellow with cinnabar markings and a white column. The outer portion of the lip is creamy white. The flower is fragrant; alas it only blooms for a few days.

The key to growing this orchid is to have partial light, good air movement and moisture. Consistent dampness is important. Unfortunately, it is too easy to let the medium become dry - so it's time to try this orchid again. Stanhopea-lovers relish this orchid, despite blooming for only a few days.

Autumn is a good time to look for Stanhopea and enjoy the fall colors!

Until next time,

Vivi
