The Greenhouse

Get an insider's look as to what's in bloom in the greenhouse:  

  • The entrance house has a number of Cattleya orchids in bloom and these were a favorite of Marjorie Post. There is even a portrait of her with a cattleya on display in her bedroom. Cattleyas are considered the benchmark of orchids and often feature large blooms which made them very popular for corsages. The iconic coloring of these flowers are white with a purple lip but many different color combinations exist.
  • Phalaenopsis, also known as moth orchids, are lighting up the east orchid house. Found in a wide variety of colors and patterns, their common name comes from the shape of their flowers which is reminiscent of the shape of a moth. With thousands of cultivars available, there is surely something unique for every orchid enthusiast.
  • We have various Cymbidium orchids in bloom now. Cymbidiums are native to the foothills of the Himalayans. As such, they need cooler temperatures compared to other orchids and actually like a touch of frost to set flower buds. These buds then develop into long sprays of large, showy flowers. One particularly nice specimen is Cymbidium Wonderland. This orchid sports striped salmon petals and sepals with a bright red mark on its inner lip.
