Araucaria: Greenhouse Plants

FF – frost free only

Family: Araucariaceae

Southern hemisphere

There are really only two suitable for greenhouses and only one easily available which is Aravcaria excelsa, the Norfolk Island Pine. In its natural habitat it will reach 61 m (200 ft). However, these graceful trees make excellent specimens when young and do not grow fast when restricted to pots. Culture is very simple. Avoid potting on too quickly. Having arrived in its final pot size it should be top dressed annually. Feed well during summer while growing and less frequently in winter when it will be semi dormant. This will prevent its needles from going yellow. Propagation can be by seed which are large and beautiful, being some 4 cm (1-1/2 in) in length and a reddish-brown colour. Germination should take place at 21°C (70°F) in the dark but as soon as this starts the temperature should be dropped to 10°C (50°F) and good light given. Should no propagating case be available the airing cupboard will do instead.
