Three varieties, bigibbum , superbum and compactum . Dendrobium bigibbum is highly variable and many forms exist. Note one example with white tips. Cultivation: water copiously in summer and refrain from watering in winter. Fertilise with high nitrogen from September until New Year. Then low nitrogen until end of flowering. Needs good air and good drainage. Grow under 50% shade.

Dendrobium bigibbum var . compactum 'Lamotte' x 'Dark Beauty' Dendrobium bigibbum var . compactum ‘Blue Moon’ Dendrobium bigibbum 'Lilac' Dendrobium bigibbum 'Red Lip' x 'Top Hat' Dendrobium bigibbum var . alba Dendrobium toressae • East Coast of Australia from Cairns to Innisfail • Epiphyte and lithophyte. From Sea Level to 1000m. Can grow in full sun. • Quite hardy. Forms extensive mats. • Cultivation – On slab. Copious water in summer but less in winter. Grow under 50% shade. Fertilizer – low nitrogen in warmer months. Cattleya bowringiana • Central America – Honduras, Guatamala, Belize. • Epip hyte, lithophyte. Along streams and on cliffs often in full sun. • Requires bright light and humid conditions. • Cultivation, In pot. Medium bark but with good drainage. Water twice a week in the warmer months and once every ten days in the cooler months. Fertilize with high nitrogen three consecutive weeks and with low nitrogen the fourth week. Flower booster in January and February does help.
