Pygmy sundews reproduce asexually using specialized scale-like leaves called gemmae. Tuberous sundews can produce offsets from their corms. In culture, sundews can often be propagated through leaf, crown, or root cuttings, as well as through seeds.

Full Answer

Are sundew self pollinating?

Sundew flowers are often self-pollinating, so they do not need to receive pollen from a second flowering plant in order to produce seeds.

How does a sundew grow?

Once an insect becomes stuck, nearby tentacles coil around the insect and smother it. Sundews can reach a height of up to 10 inches (25 centimeters). However, some species are tall and with a vine-like appearance, while others hug the ground, making their size variable.

How do you get seeds from a sundew plant?

Harvest the flower stalk early by snipping the stalk off at the base of its attachment to the plant, and folding it inside of a full sheet of paper. Then, you can wait for several weeks for the stalk to completly dry out, and you can unwrap it carefully to collect the seeds.

What happens if you touch a sundew?

Although Sundew plants aren't technically poisonous, these plants contain something called “contraindications”. If you were to touch a carnivorous plant too often, you might experience irritation in the digestive tract.

Is sundew a boy or girl?

Sundew is a female LeafWing dragonet and the main protagonist of The Poison Jungle.

Can sundews survive without insects?

While many people think these plants must be fed every day, like an animal, carnivorous plants can actually go for long periods without any insects. If you have a sundew that you want to feed, you can do so if you are careful not to give it too much.

Should I cut the flowers off my sundew?

As long as you keep feeding the plants pretty heavily, it won't harm them.

Can you eat sundew plants?

The answer is it depends on the type of plant. Furthermore, it also depends on whether you want to eat something that is not tasty. From the taste point of view, carnivorous plants such as Venus Flytraps, Sundews, Pitcher Plant, etc. may not make good eating for you.

Are sundew plants edible?

Wildflowers of the Adirondacks: Roundleaf Sundew appears to have limited edible or medicinal uses. Roundleaf Sundew (Drosera rotundifolia) on Barnum Bog (20 July 2019). Roundleaf Sundew appears to have limited edible or medicinal use in the US. Native American groups reportedly made little use of this plant.

Can you feed sundew dead bugs?

Unlike with flytraps, the bugs don't have to “act” alive to stimulate digestion. Dead ones work just as well. Some growers who keep live insect food for reptiles also feed their plants with these. I don't recommend buying live insects just for feeding plants.

Why is my sundew going black?

Why are my sundew leaves turning black? Sundew leaves turn black if they've been moved from a location to another. In this case, it's a stress response. This also happens if they have been put in direct sunlight for too long.

Is sundew a poison?

What is a sundew?

What did the early settlers use to make ink?

Early settlers extracted a red fluid from sundews to use as ink.

Do sundews eat insects?

These plants feed on insects. Mosquitoes are abundant in the sundews’ preferred habitat and can make up a significant portion of their diet in these locations. Sundews can kill a trapped insect in about 15 minutes, but may digest it over a few weeks.

How does drying a drosera flower work?

The drying process usually breaks down the protective barrier at the top of the bud, allowing seeds to fall out and disperse freely when the flower stalk is blown by the wind or struck by raindrops ( etc.). Some Drosera species have extremely unique methods of dispersion (ie splash cups or water dispersion).

Why do plants need to be cross pollinated?

Cross-pollination encourages genetic diversity and "fitness" or survivability of the organism. For example, consider a D. graomogolensis that is capable of tolerating warmer temperatures, but is succeptible to attack by a species of fungus. If self-pollination was the primary means of reproduction, then the plant would be able to produce many offspring, but if the fungal invader were to attack, all the offspring nearby would likely also be infected and die. However, if cross-pollinated with a D. graomogolensis several hundred feet away with a resistance to the fungus, but no tolerance for heat, then some of the offspring may inherit tolerance of warmer temperatures AND resistence to the pathogen. In this case, hybrid vigor would allow these offspring to thrive and the species will have a better chance at surviving and competing long-term.

What are the four types of sundew flowers?

Sundew flowers are "complete" because they have all four types of flower structures, or "whorls": 1.) sepals, 2.) petals, 3.) carpels, and 4.) stamens (all can be seen in the diagram below). All rights for the above diagram belong to EnchantedLearning.com. Flowering.

Why won't my sundew flower open?

They will usually still produce plenty of seeds, but this can reduce the amount of seed that is produced. Bright light intensity and other factors, such as temperature and humidity can encourage the flowers to open fully.

Why are Drosera plants considered complete?

The flowers of Drosera species are classified as "perfect" and "complete" in plant biology because they contain both male and female reproductive organs in the same flower and can produce viable seeds by self-pollination (unlike Nepenthes).

Why is cross pollination important?

Cross-pollination encourages genetic diversity and "fitness" or survivability of the organism. For example, consider a D. graomogolensis that is capable of tolerating warmer temperatures, but is succeptible to attack by a species of fungus.

What is the most rewarding part of growing sundews?

One of the most rewarding parts about growing sundews is spreading seeds around to other growers who are anxious to grow these amazing plants.

What are some examples of sundews that won't work?

Examples of sundews that won't work are Pygmy sundews, or annual sundews (i.e. D. burmannii or D. indica). When taking root cuttings, make sure the plant has at least a 2-inch root, or else, you may end up killing the mother plant in the process.

How to get adult drosera?

Root cuttings are by far the fastest way to obtain adult plants by means of propagation. Root cuttings will only work on thick-rooted Drosera species such as: D. adelae, D. admirabilis, D. binata, D. capensis, or D. falconeri. Examples of sundews that won't work are Pygmy sundews, or annual sundews (i.e. D. burmannii or D. indica). When taking root cuttings, make sure the plant has at least a 2-inch root, or else, you may end up killing the mother plant in the process. You can cut the root cutting into sections, or leave the strand as a whole unit. You can set up a root-cutting propagation container in 1 of 4 ways:

How do sundews grow?

Seed is a very good way to produce large amounts of plants. Sundew seeds are very tiny. Some species of Drosera have such small seeds, it looks like black powder. Seeds are very commonly used in Tissue Culture since they can be easily sterilized. For most annual sundews, seed is the only method of propagation. Leaf cuttings and root cuttings don't seem to work. Most sundews produce seed through self-pollination. However, there are exceptions to this, such as the Petiolaris complex and Queensland sundews. These sundews must be cross-pollinated with another clone or with a sundew that is closely-related. Some sundew seeds germinate in only a few weeks, while some tuberous sundews can take up to 5 years to germinate. To learn how to germinate common sundew seeds, visit my Germination Guide. Some sundews can grow to maturity from seed in only 4 months.

When using this method, you will not have to seal the top of the container, as long as the soil is always soggy at the top. Give as much light as possible (I'd recommend using lights unless you want to experiment trying this outdoors. Keep the water level high until you notice new growth, or small roots protruding from the cutting. Then you can gradually lower the level until the plantlets are completely established.
