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. This mucilage rolls down the plant, attracting sugar-loving insects day and night. The mucilage has enzymes which digests them so that the plants can get the nitrogen it needs from it. Like all plants, the sundew makes its own food, and just uses insects for nitrogen and other nutrients. These tiny flowering plants are about tall, about as tall as an adult's hand, though some climbing sundews can be much taller. One species of sundew, the "Drosera erythrogyne", grew up to . Sundew roots are not very strong. They are usually simply for taking in water and keeping the sundew firmly planted to the ground.
