Botany—Living Terrestrial Plants
Classroom Plants
Plants that are ideal for cultivation in the classroom because of their relatively simple care requirements and numerous opportunities for experimentation and study. Each is supplied as three plants in separate pots.
★MAINTENANCE: All of the plants listed below do well in moderate to high light at temperatures of 18–25 °C. If using artificial lighting, plants should receive 12–15 hours of light per day. Fertilize once a month with an all-purpose fertilizer—following package directions for mixing and diluting. We recommend a soil mix consisting of 30 to 40% peat—typical of most all-purpose potting mixes. Keep soil slightly moist (not wet) and mist plants weekly. For Coleus and geraniums, periodically pinching back stem tips will encourage fuller growth and also promote flowering.
Carnivorous Plants
Fascinating and beautiful plants that should be present in every biol- ogy laboratory. Although primarily photosynthetic, these plants exhibit elaborate adaptations to carnivory which are believed to enable them to thrive in nutrient- and nitrogen poor soils. Carnivorous plants are shipped bare-root, ready to be transplanted.
★MAINTENANCE: Maintain carnivorous plants in moderate light at temperatures from 18–24 °C. These plants require humid terrarium environments to do well. Keep terraria covered with glass or rigid plastic to maintain humidity—removing the cover once a week for several hours to ventilate. Prepare the growing medium by adding a 1" layer of gravel to the terrarium and then a 2–3" layer of acid bog soil (two parts peat to one part garden/potting soil). Complete the medium by spreading a layer of sphagnum moss over the soil. Prepare the plants by loosely wrapping the roots with sphagnum. Place the plants in the medium at appropriate depths: pitcher plants so the roots can reach the gravel layer, Venus flytraps so roots are just above the gravel layer, sundews so roots are close to the soil surface. Water the medium thoroughly enough so that there is stand- ing water in the gravel layer. Keep the soil moist at all times and mist the plants daily.

LM1140
Coleus. Because of its characteristic variegated leaves, this plant has long been popular for studies involving photosynthesis and starch production.
$27.85
LM1141
Geranium. Hardy and easily propagated. As easy to maintain as any common plant.

Price/Each
LM1137
Pitcher Plant (Sarracenia). Hollow, pitcher-shaped leaves that are extremely attractive to insects. When insects enter the leaf, escape is prevented by downward-pointing hairs. Cultivate in acid-bog terraria.
$15.10
LM1138
Sundew (Drosera). Long thin leaves which terminate in disc-shaped pads. Hairs radiating from the pads secrete a sticky substance that traps insects. Relatively easily maintained in warm, humid environments.
12.60
LM1139
Venus’ Flytrap (Dionaea). Clamshell-like leaves with
a reddish inner surface that serves to attract insects. Successive stimuli on this inner surface induce the trap
to rapidly close. Maintain on sphagnum/peat in bog terraria.
