WHAT ARE DROSERA?
Drosera or Sundews are a group of beautiful carnivorous plants.They use an active glue trap much
like a fly paper trap. The tentacle-covered leaves come in various shapes and forms making them a very interesting plant to cultivate and collect. At the end of each tentacle the plant produces a droplet of sticky substance that looks like morning dew when the sun shines on it, thus the name Sundews. The droplets of “dews” promise sweet delicious nectar to unsuspecting insects. They can be as small as 1cm in diameter or as big as 2-3 feet in diameter. Some are annuals, while others are perennials.
HOW TO GROW DROSERA:
Drosera come in a wide variety of forms and from all around the world, the common name applied to these fascinating plants is Sundews. Currently there are something like 130 different varieties available with differing growing needs. Some look like tiny bottle brushes whilst others resemble tall slender reeds. All of them have tiny tentacles tipped with a globule of glue like material which is used to trap their prey. They range in colour from pales green through red but most of them have red tips on the tentacles. The leaves of Sundews are semi active, when they capture prey the leaf will close in around it and dissolve the insect with enzymes that are secreted by usually the central part of the leaf. Sundews will produce flowers in the spring and summer which can be white, pink or yellow and are borne of slender stems which are usually an inch or two above the tentalces. The plant pictured below is Drosera capensis and the leaves reach a height of between 3 and 4 inches in length with the top third having the sticky tips.
| Temperature: This varies considerable between species, some require tropical conditions whilst others will happily survive in almost Arctic conditions. See the individual species for details but the commonly grown types require a minimum of 40F Humidity: Humidity is not an issue for most of the sundews. Light is what gives them the ability to produce dew, not humidity. Generally 35% and better is fine once they get acclimated to it. Watering: Sundews should be kept standing in 1 inch of water from April through November and be kept just damp for the remainder of the year - there are some Sundews which need completely drying out during the winter 'resting period', see the species pages for more. | |
| Light: These plants will benefit from being placed in a bright position and can stand full sun provided they don't go short of water. These make great windowsill plants and will catch insects all year round. Compost & Watering: These plants should be grown in a mixture of 50% sphagnum moss, 30% sphagnum peat, 10% sharp sand and 10% charcoal. They should always be watered with either soft water (not from a water softener!) or rain water which has been gathered. Feeding: They do not need feeding with liquid plant food but you should drop fly's and other small insects on to the leaf if they seem not to be catching many things of their own. | |
