From my selected open area-Folsom Lake
My keying led me to Acacias, so while I’m not 100% that this is a Taiwan Acacia it’s at least close.
Medium sized tree with medium green leaves. Leaves are alternate and holly-like. Leaves are thick and spiney. Bark is medium brown.
Messy looking small shrub. Grows upward with small, yellow flowers. Leaves grow at the base of the stems and are fuzzy and green. Looks like a "weed"
Small shrub with upward growing flowers. Flowers are a dark, burnt, red and appear either dry or dead. New stems are green.
Bright green, dense shrub growing upward. Leaves are very small and sharply lobed, with a very interesting shape. Leaves are alternate.
Small shrub with many spines on all parts of the stem. Flowers appear dry/dead and also have a spiney look to them. Flowers appear to have some pink color.
this plant is sandwiched between PCH and the beach, sprouting up in the dirt.
Purple flowers growing from what look like some sort of succulent, not entirely sure though.
beachside oats
Common yarrow in mid bloom. White flower in the middle.
