Help ID plants from Santa Monica Mountains

Hi,
I'm planning a group hike in the Santa Monica Mountains. To tell people a little about plants, I photos of plants that appear on the hike. If someone could help me ID them, it would be super awesome.

The location of the first two plants is in the shade under trees near a seasonally dry creek.
* Plant 1 is a human-high stalk with big, green leaves.
* Plant 2 is a bush that's more wide than high. It has clusters of small white flowers with a prominent yellow in the center. The flower petals are pulled back. There are also pea-sized green berries growing. Is this a kind of nightshade plant?


The location of the last plant is on the sunny hillside surrounded by chaparral.
* Plant 3 is a tough, dry bush about knee high. The leaves are tiny, long, and hard. The flowers are pink-brownish in a cluster. Is this a type of sagebrush?

#2 - yes, Solanum sp. (S. americanum or S. nigrum)

 

1 - Nicotiana glauca (an invasive weed in your area)

 

Plant #3 possibly a buckwheat perhaps California Buckwheat (Eriogonum fasciculatum)? https://writingfornature.files.wordpress.com/2012/11/buckwheat-bush-010.jpg

 

#2 ... or S. douglasii, if the anthers are over 2 1/4 mm long.

 

Thank you for the excellent information!
