Why did sundew get the name Drosera?
Description. Its scientific name is from the Greek δρόσος: “drosos” = “dew, dewdrops”. Its English name is sundew, from Latin ros solis, meaning “dew of the sun”. Both names describe the sweet-smelling, sticky mucilage (goo) that comes down the ends of tentacles on each flower stalk.
What is a dew of the sun?
Dew is moisture caused by condensation of water vapor in the air. The air heats up again, more quickly that the objects. This causes condensation — dew — on grass, plants, car windshields, and so on. Dew quickly evaporates in the sun. That’s why you really only see and feel it early in the morning during summer.
Is sundew a name?
Both the botanical name (from the Greek δρόσος: drosos = “dew, dewdrops”) and the English common name (sundew, derived from Latin ros solis, meaning “dew of the sun”) refer to the glistening drops of mucilage at the tip of the glandular trichomes that resemble drops of morning dew.
Is the Sun Dew native to BC?
This species is found in wet, nutrient-poor sites like bogs, fens and wet meadows, from low to middle elevations. It is found throughout coastal and interior BC, and has a broad range extending across the Northern Hemisphere in much of North America, Europe, and Asia.
What does the Venus flytrap do?
The Venus flytrap is a flowering plant best known for its carnivorous eating habits. The “trap” is made of two hinged lobes at the end of each leaf. On the inner surfaces of the lobes are hair-like projections called trichomes that cause the lobes to snap shut when prey comes in contact with them.
How is dew formed at night?
Dew forms as temperatures drop and objects cool down. If the object becomes cool enough, the air around the object will also cool. Colder air is less able to hold water vapor than warm air. Warm, humid air is full of moisture that can condense during calm, cool nights.
How do Cape sundews eat?
Sundews are “flypaper” plants that trap prey in sticky hairs on their leaves. They make up one of the largest groups of carnivorous plants. Long tentacles protrude from their leaves, each with a sticky gland at the tip. Once an insect becomes stuck, nearby tentacles coil around the insect and smother it.
Is Drosera poisonous?
No, sundew plant is not toxic.
Where can I find Sundew?
sundew, (genus Drosera), genus of approximately 152 carnivorous plant species in the family Droseraceae. Sundews are widely distributed in tropical and temperate regions, especially in Australia, and are common in bogs and fens with sandy acidic soil.
How do you grow Drosera rotundifolia?
It’s a good idea to place it in a terrarium or Wardian case to maintain humidity around it. Give it a winter rest. Sundews are perennials that go dormant in winter and need a cool rest. Keep your plant moist and cool during dormancy, with temperatures between 32-50°F/1-10°C (it will tolerate some frost).
Why can’t Venus flytraps eat ants?
Venus flytraps do not rely solely on consuming flies. Most ant species are small enough to fit inside the leaves of a Venus flytrap. Venus flytraps sometimes struggle to capture bugs that are too large for their leaves. Ants are an appropriate size for most young and mature plants.
