Drosera rotundifolia – Roundleaf Sundew is indigenous across the northern hemisphere and is best grown outdoors, as it requires a definite winter dormant period. It catches its prey with leaves covered in red glandular hairs that secrete a sugary substance which attract and hold insects. Pots of Drosera should be kept in saucers of rainwater. Grows 4-6″ high by 6-9″ wide. Zone 6.
Sarracenia flava var. maxima – This variety of Pitcher Plant has pure yellow pitchers, with no red tinting. They can be grown in a minimum 18″ wide plastic or glazed ceramic container with no drain holes, and a soil medium of 2-3 parts sphagnum peat moss to 1 part washed sand. Prefers part to full sun and no additional fertilizer. Grows 18-24″ high by 12-18″ wide. Hardy to zone 5.
Dionaea muscipula – The Venus Fly Trap is the quintessential carnivorous plant and is only found in a 60 mile radius of North and South Carolina. It catches its prey with active traps of modified toothed leaf lobes that are triggered by sensory hairs and close. It needs no fertilization (it gets its nitrogen from digesting insects) and requires distilled or rain water. Zone 8.
Sarracenia rosea – This species of Pitcher Plant was once thought to be a variety of S. purpurea, but differs with its pink flowers and thicker pitcher lip. It is one of the easiest Sarracenia to grow and tolerates partial shade well. This temperate species also requires a dormant period (3 months) and is best grown outdoors in a container as described above. Pitchers grow to 6″ high. Zone 7.
Nepenthes alata – This tropical species from the Philippines is known as Winged Pitcher Plant or Monkey Flower. The pitchers develop as a swelling at the end of midrib vein of the leaf and they are quite variable, but usually green with some red tinting. It requires high humidity (mist once a day with distilled water) and no direct sun. Most often grown as an indoor hanging basket. Z11.
