Drosera Rotundifolia
Drosera rotundifolia, the Round Leaf Sundews, is found in all continents in the Northern hemisphere, it is circumboreal. This is a perenial which can reach 35 cm, 14 inches. The leaves are edged with long hairs, each with a sticky drop on the end of the hair. Hairs are red in colour. Leaves can be as wide as 1 cm. Each leaf is entire, circular, covered with sticky, shinny, red tentacles. This Drosera develops small white flowers on 3" long flower stems in Summer. The flowers have 5 regular parts and are up to 7 mm wide. They are white sometimes pink. Blooms first appear in early Summer and continue into mid Fall. The plants eat small insects to provide them with the azote which is lacking where it lives. When an insect becomes entangled in the hairs, the leaves bend inwards so that the insect comes into contact with fine, inner hairs. Enzymes are produced by the hairs which dissolve the insect, which is then absorbed by the leaf. Only the insect's exoskeleton remains which blows away when the leaf hairs uncurl to become erect again, ready for the next meal. Hardiness zone 3-8, (-37øC/-35øF, -10øC/-15øF) in Winter. They should be grown in bright light, but with protection from full midday sun. In cloudy coastal areas, artificial light is a required. They like cool temperatures. Temperatures should be kept between 20øC/68øF, 25øC / 80øF in growing season. They require seasons in order to survive long term. They need a dormant period of about 3 months in the Winter. In the Winter, when food is scarce the leaves die back to form a tight resting bud. The typical heated home is too warm in the Winter. During dormancy they should be kept cool and only damp. The entire planter may be moved to an area where the temperature will remain below freezing point, down to -10øF. Protect from dry freezing wind during deep freezes by covering the plant with black plastic. Uncover the plant when the deep freeze and dry freezing wind is over. Otherwise, place it in a refrigerator for 3 months in a ziplock bag. At this time the compost should be allowed to dry slightly. It grows in bogs, swamps and wet acid soils. A soil mix of one part peat moss for one part sand usually works well. There's no need to fertilize, as the plant relies on insects for food. Requires consistently moist soil; do not let dry out between waterings. Drosera Rotundifolia likes short pots to be close to the water level and to be very wet when growing. Water must be distilled or rain water because they do not tolerate city or hard water. It is a good idea to place a pie pan or large saucer, with about an inch of water in it, under the pot. Elevate the pot by placing pebbles under it so that the base of the pot is barely in contact with the water, not submerged; the growing medium must stay moist, but never soggy. This will keep the humidity around the plant higher and it will ensure that the plant has a constant source of moisture. The humidity should be between 60-80%.

Germination The seeds require 6 weeks cold stratification. Sow directly on the surface of your moist but not soaked soil mix. Do not cover them with any medium, the seeds are really tiny. Once it's time to take the seeds out of cold stratification, cover the top of the pot with clear plastic so the humidity will remain high, place them in an area with real nice strong light and keep the temperature around 20øC/68øF, 25øC / 80øF. Make sure to be gentle at all time with the new seedling, to not destroy it, it is very small.

When you see some tiny plants starting to sprout, slowly open the top of the pot, a little each day, so that the new seedlings don't go into shock from the humidity being lowered too quickly. After cold stratification, germination usually occurs in 1 to 3 months, but it can take longer, depending on their degree of unbroken dormancy, don't give up. Be gentle with the new seedlings, not to destroy anything. Make sure that it gets good air circulation.
Scarification / Stratification It creates a cold and moist environment for the seeds. This will break their dormancy. Place the seeds on top of a prepared soil mix. The pot is then placed into a ziplock bag with approximately an inch of water on the bottom of the bag. Close the bag shut and place it into the salad crisper compartment of your refrigerator. Make sure to check the seeds often. If fungus or mold appears treat it with a fungicide.
