Cattleya ‘Green Mist’

Cattleyas are epiphytes and enjoy warm, humid conditions, with some air movement. Water them when the growing medium is dry. A new flower spike grows from a dormant bud each year. Cut this back to the stem after flowering.

Dendrobium ‘Thailand Black’

The stunning flowers of dendrobiums can last for about six weeks. Keep plants in warm conditions (min 13°C) and water when the growing medium is becoming dry. Dendrobiums can reproduce by forming baby plantlets called keikis.

Dendrobium thyrsiflorum

Dendrobium thyrsiflorum is an epiphyte that produces blooms once a year from each flowering stem. Water it with rainwater and liquid fertiliser when its growing medium becomes dry during summer and mist the foliage frequently. Water less in winter.

Disa aurata (golden disa)

Keep Disa aurata (golden disa) on a cool, bright windowsill, out of the sun. Disas are terrestrial orchids that grow with their roots permanently in wet soil. Keen growers sometimes use an aquarium pump to circulate water continually around the roots.

Disa uniflora

This red disa, Disa uniflora, is the emblem of South Africa’s Western Cape. Like the golden disa, it needs permanently wet conditions and benefits from watering with a weak fertiliser solution. Occasionally, pink or yellow flowers develop.

Phalaenopsis ‘Golden Beauty’

Grow Phalaenopsis 'Golden Beauty' in a warm room with low light and high humidity. Plants are usually sold growing in bark compost in clear plastic pots, so the green roots can photosynthesise. Don’t be tempted to repot, as these conditions are perfect.

Phalaenopsis ‘Mini Mark’

With tiny flowers only 2.5cm wide, Phalaenopsis 'Mini Mark' is a beautiful little moth orchid should be grown in the same conditions as ‘Golden Beauty’ (above). Like larger-flowered varieties, it can keep its blooms for about eight weeks.

Prosthechea prismatocarpa

With plentiful, long-lasting, scented flowers, epiphyte Prosthechea prismatocarpa grows on trees in the mountains of Central America. It likes bright light, but not direct sun. Let the growing medium dry slightly between waterings and water less in winter.

Vanda ‘Rothschildiana Pink’

Vandas have very long roots and are often grown in baskets so the roots can hang down. They need warm and bright, but not sunny, conditions. If the plant gets too tall, you can cut off the top plus a few roots and replant it. The variety shown here is 'Rothschildiana Pink'.
