Different Irrigation Ditches in Upper Imperial Valley (L and M Laterals) – Some with Arrowweed
A morning walk (November 2013) along irrigation ditches in the Imperial Valley turned up a few interesting plants and a frog:
- Pluchea sericea - Arrowweed Pluchea
- Heliotropium curassavicum - Salt Heliotrope
- Tamarix pentandra - Saltcedar, Tamarisk
- Medicago sp. – Alfalfa
- Washingtonia filifera - Desert Fan Palm stump
- Lithobates berlandieri – Rio Grande Leopard Frog
Pluchea sericea, a member of the Asteraceae family, has an interesting story. Its straight stems were used in making arrow-shafts, in the construction of walls and roofs of mud huts, and in basket making. On the ditches we walked, the arrowweed was thick at times.
