Plants—Living, Terrestrial
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 to 25 °C. If using artificial lighting, plants should receive 12 to 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 classroom. 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 to 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" to 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 Venus flytraps so roots are just
above the gravel layer. Water the medium thoroughly enough so that there is standing water in the gravel
layer. Keep the soil moist at all times and mist the plants daily.

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.

Germinate Seeds
There are several things you can do to ensure seed germination and growth.
An all-purpose potting mix (such as Jiffy Mix®) or milled sphagnum moss
make excellent germination media. The starter medium should be placed in
seed trays or small pots to a depth of two to three inches. Some seeds can be
soaked for 12 to 24 hours prior to planting to speed germination. An easy way
to do this is to wrap the seeds in a moistened paper towel.
Most seeds should be sown at a depth of up
to three times their diameter. Small seeds can be
scattered over the soil and lightly pressed down.
Water the seeds by gently sprinkling with warm
water. Cold water could lower the temperature of
the soil below the germination level. Always keep
the soil moist. Cover the seeds with a pane of glass
or plastic wrap to trap heat and conserve moisture.
Try to keep the seeds at 22 to 27 °C. After
the seeds have germinated, remove the glass and
use fluorescent lights to warm the seedlings. At
this point it is a good idea to thin out the seedlings—leaving only the
largest and strongest. As soon as the seedlings can be handled, transplant
them to larger containers, leaving enough room for each plant
to grow unrestricted. Water regularly. Dilute (half-strength) fertilizer
may be applied three to four weeks following germination.
