Growing Indoors

A number of carnivorous plants make good house plants (see table 6). A position near a south-facing window suits the majority of them. The tall Sarracenia species in particular require full sun and will otherwise grow into long thin pitchers which are unable to support themselves. All pitcher plants need maximum light to develop their colour. However, there is some risk of damage from the rays of the sun which, when magnified by glass, may cause leaf scorch. Plants with fleshy leaves, especially Pinguicula, are most susceptible and should not be placed in direct sunlight. Those Sarracenia which produce large amounts of nectar on their pitcher lid, like S. flava, may also suffer slight leaf scorch unless protected against the strength of the midday sun.

Table 6: carnivorous plants suitable for growing indoors Position Plants

Windowsill in direct light Sarracenia flava - dislikes too much winter heat.

S. purpurea venosa - horizontal pitchers, easy.

S. xcatesbaei - beautiful hybrid of the above two.

Drosera capensis - easy, grows and flowers quickly.

D. spatulata - easy, small rosette. D. aliciae - easy, red hairs on green leaves.

Cephalotus /ollicularis - unusual appearance.

Dionaea muscipula - easy, trap colour red in sun.

Windowsill in indirect light All tender Pinguicula - good flowers, dislike cold.

Most (Jtricuiaria - small and fascinating.

(J. sandersoni - almost always in flower, easy.

Shade Pinguicula moranensis forms -

P. caudata and P. mexicana.

A natural hybrid, Sarracenia x catesbaei has startling yellow pitchers contrasting against brick red flowers and is easy to grow

Many Pinguicula thrive on a north-facing windowsill or one that receives only indirect light. They can be protected from short periods of direct sunlight by placing them behind ordinary household net curtains. Some of them, including the commonest forms of P. moranensis (usually sold under the names P. caudata and P. mexicana) can be grown in shade, away from a window.

Carnivorous plants grown indoors require no special treatment. They can be grown in a pot of the appropriate compost and placed in a plastic saucer containing 1 in. (2.5 cm) of rain water or distilled water. During dormancy the plants should not stand in water but should be watered once a week to keep the compost damp. Tender plants, especially Pinguicula, should be moved away from a window when outside temperatures fall below 50 °F (10°C).
