From the top to bottom of the forest here are some of the most commonly found and easy to identify flora growing in Peterson Creek in Kamloops BC. This article is a work in progress and updates are welcome.
Rocky Mountain Juniper
There is one Hawthorn I know of in the park and a single horse chestnut.
Red Osier Dogwood
There are a handful of garden cultivars such as cotton easters and barberries that I assume have been ‘planted’ by birds.
Prickly Pear Cactus
Missing from this list are the arrowleaf balsamroot, gallardia, mariposa lilies and larkspur that are a less common sight due to people picking them.
Please do not pick wildflowers unless you know the FULL lifecycle of that plant.
