Carpenter Valley Wildflowers

Carpenter Valley Wildflowers - Carpenter Valley, looking across a fen into the valleyCarpenter Valley is an amazing nature site owned by the Truckee Donner Land Trust (TDLT). There is a wide variety of habitats here, including a wet meadow, fens, dry woodland, and stream/riparian. It is located near Truckee in Nevada County. I was fortunate to be able to hike through a portion of this property on a docent-led wildflower hike with the Sacramento Valley Chapter of the California Native Plant Society.

This area is not open for public access unless you are on a guided hike with a TDLT docent. Information on these hikes can be found on the TDLT Carpenter Valley website. There are plans to build an access trail that will be open to the public at a future date, and you can sign up for the TDLT newsletter to keep up to date. 

The Flowers

Here’s a sample of a few of my favorites from this hike. We had a limited amount of time on this hike so some of the pictures aren’t as clear as I would like.  Also, I have not yet ID’d all of the flowers we found, so I would appreciate any help you can offer. For the unidentified flowers I have additional photos of leaves, etc., if you are interested in helping. 

Hairy owl’s clover was a fun flower to find. I’ve not come across this species before.

Scarlet gilia is always fun to come across.

I’m particularly fascinated by the variety of Calochortus in California. This one is Leichtlin’s mariposa lily.

I love vernal pools, and we found one on this hike. There was a carpet of white Wooly marbles, and nestled amongst them were a very, very tiny popcornflower. Just a few millimeters across.

Harsh Popcornflower, Plagiobothrys hispidulus

At the far end of the valley, near the fen, we found a few Sierra bog orchids.

At that same location we also found Great polemonium (aka Tall Jacob’s Ladder), which is another flower I’ve not come across before.

Carpenter Valley Wildflower Listing

Here’s a listing of the native plants that we found on this visit (at least, the ones I have pictures of). The ones listed in color are endemic to California (that is, found only in California). Note that there were many more flowers at this site than I show here – we weren’t able to access the sensitive fen area on this hike. I’m hoping that the planned TDLT trail will provide some access to this amazing portion of the valley.
