Columbines

This past weekend while visiting the Gardens of the World in Thousand Oaks I noticed these weird flowers in the English garden area and was immediately fascinated:

Obviously the elongated parts on the backside were eye catching and screamed "EAT HERE" to hummingbirds. I also thought their double layers of petals and interesting color combinations were so beautiful, unique and looked like some weird hybrid of multiple flowers.

(I LOVE the shadow on the yellow petal on the upper left.)

FINALLY I found a plaque in the garden... Columbines! Turns out I love Columbine flowers!
