"Firecracker" Marigold, also from my garden
I've got a couple.
This is a Cypress tree at night near Carmel, CA.
Here are the roots of a fallen redwood tree, Humboldt, CA
not sure if its deadly but i wouldnt eat it. found in my back yard.
They are succulents so don't need much watering, dry environment. etc
They can be part of terrariums
