Dendrobium bigibbum var. phalaenopsis
Cooktown Orchid
Original:The Cooktown Orchid is the floral emblem of Queensland. Plants grow to 80 cm in height. They are easy to grow if the right conditions are satisfied. Dendrobium species are mostly epiphytic, occasionally lithophytic. These orchids grow throughout summer, but become dormant during winter. They come to life again in the spring when there is a rapid growth of new roots. They are popular orchids and over the years, many hybrids have become available. New:Dendrobium species are mostly epiphytic, occasionally lithophytic. Epiphytic orchids use other plants, rocks or fallen trees for anchorage. They have modified aerial roots that can sometimes be a few meters long. Lithophytes are plants that grow in or on rocks. Lithophytes feed off nutrients from rain water and nearby decaying plants, including their own dead tissue.These orchids grow throughout summer, but become dormant during winter.

Dendrobium phalaenopsis has, lance shaped green leaves, and a tall stem with pinkish-mauve to lavender-purple (and sometimes almost white )flowers. In the wild it blooms in the dry season, indoors it blooms throughout the year.

Flowering
From Early Spring TO Late Winter
Many orchids do not have a flowering season and flowers may be produced at any time if the right conditions are being met. Once the flowers have faded, cut the flowering stalk back to just above the second node (joint) visible beneath the spent flowers. A new flowering side shoot may develop.Terrestrial orchids grown outdoors will mostly flower in the summer months. Flowers can last for several months.
Planting young plants
From Early Autumn TO Late Autumn
Sometimes small plantlets (keiki) appear from the nodes on the flower stems. Detach the plantlets when they have developed several good roots and pot them up in orchid compost. Water them sparingly at first, but mist them daily. Always use a proprietary orchid compost. Ensure good light levels in winter, as these are essential to encourage flowering. An east- or west-facing window would be ideal. Move to a shadier spot in summer and protect from direct sunshine. When planting terrestrial orchids outdoors, plant in semi-shade, no direct sun at midday. A very suitable place would also be on the north side of a building. Most orchids are woodland plants and therefore prefer cool sites, which do not become too dry and hot during summer. Places where ferns thrive are also suitable for. Don’t plant your orchids close to trees or big shrubs because their roots are effective competition for water and nutrients! Autumn is the best season for planting. Spread out the roots in the upper 10 cm (4 inches) of the soil, the rhizome 2-3 cm (1 inch) below the surface, shoot buds upwards. Fill in the remaining substrate without compressing it, and water thoroughly.
