- Common Twinpod [C] Physaria didymocarpa (Hook.) Gray
-
WARNING: If you are pregnant, do not ingest this plant.
Common Twinpod, a part of the mustard family, is a small, low-growing plant with dark green leaves. It has a very long taproot that travels on and on underground, searching for water. You could dig up to a metre deep and still not be near the end! That long tap root helps it grow along dry cut-banks or along the gravelly margins of streams....
- Cottonwood [C] Populus deltoides Bartr. ex Marsh. ssp. monilifera
-
Cottonwood Trees grow in the river plains where we live. Elder Pete Standing Alone explained that for Cottonwood seeds to grow, a river needs to flood. The tree is part of the poplar family and quickly grows up to 30 metres and can be up to a metre wide. It has smooth, pale bark when it is young but like people, the older the tree is the more ridged and furrowed it becomes....
- Green Milkweed [G] Asclepias viridiflora Raf.
-
Green Milkweed is a thick, hairy herb that stands 60-290 cm tall. It grows in clumps in moist areas, meadows, beside fences and steam beds, in soil that is rich or sandy. It has lots of greenish white blossoms that are long and tube-shaped, with five petals. These are bunched together into a globe shape that is about 5-7 cm across. The leaves grow in pairs on either side of the stem....
- Paper Birch [P] Betula papyrifera
-
Elder Pete Standing Alone told us that White Birch and Water Birch trees give us strong wood for making things like snowshoes and axles for wheels and sleighs. It also gives us good wood for burning.
Paper birch can grow up to 15 metres. It has white or slivery gray bark and it peels off easily into thin strips, like paper. The light green leaves have lots of little teeth around their oval shape....
- Rocky Mountain Maple [R] Acer glabrum Torr.
-
The Rocky Mountain Maple is a shrub or small tree that can grow to be about 3 m tall. It is most often found near creeks or rivers, because it needs lots of water. The leaves look like regular maple leaves in a style that is called palmate or palm-like. It has seeds with little wings that allow them to float on the breeze and travel long distances....
- Yellow Angelica [Y] Angelica dawsonii S. Wats.
-
WARNING: Angelica may be difficult to tell from Water Hemlock. Water Hemlock is one of the most poisonous plants in North America. Only 1.2 ml of the root may be fatal in 15 minutes. Positive identification is critical!
Yellow Angelica grows in moist meadows or along stream banks. It grows 1 to 2 metres tall on a hollow stem. The tiny, yellow flowers on top look like a fireworks burst, all going out in a different direction....
