Fireweed (Epilobium angustifolium) is a perennial herbaceous plant in the family Onagraceae native to the temperate and boreal regions of the Northern Hemisphere. This flower is a pioneer species, meaning it is one of the first plants to colonize an area after an it has been cleared by a fire. In Alaska, jellies, syrups, candies, and ice creams are made from fireweed. Some Native American groups, such as the Dena’ina, use the plant for medicinal purposes.
The grey granules are pollen from Viburnum tinus, or the snowball plant. One of them has started growing a tube that transfers the sperm to the ovule of a receptive ovary. The yellow granules are pollen from another species of plant.
The Cape sundew (Drosera capensis) is a species of perennial sundew native to the Cape in South Africa. The brightly colored tentacles (modified leaves) secrete a sticky substance that attracts and traps insects. After an insect is trapped, the tentacles roll inward via thigmotropism (touch-sensitive movement). The plant secretes digestive enzymes that dissolve the insect’s body into a kind of nutrient soup which the sundew absorbs.
The Korean bellflower (Campanula takesimana) is a species bellflower bearing white to pink flowers.
Spiderwort Leaf
Spiderworts are plants belonging to the genus Tradescantia, herbaceous flowering plants that can be found growing in moist tropical to subtemperate habitats around the world. In the North American prairie states, many of these plants are known as “cow slobber” because of the gooey, stringy sap they produce. When stretched out, the sap can also resemble strands of a spider’s web, which probably gave rise to the “spiderwort” name.
This the Indian Pipe plant, an eerie-looking plant, in my opinion. Monotropa uniflora is a heterotroph. That means that it doesn’t photosynthesize. Instead, it’s a parasitic plant that relies on mycorrhizal fungi for its nutrients.
Why is it white? No chlorophyll, no green.
It’s also known as the Ghost Plant, and the Corpse Plant.
