Berlandiera lyrata... or "the chocolate daisy"

Indeed, there is a chocolate fragrance.
My plants don't look too good, being crammed between other taller plants and it looks like they need sun.
But they do bloom, spread their chocolate-y perfume around and even bless me with seeds.
What's good about this plant is that it doesn't have any pests, is not bothered by the heat and drought, and it blooms now, when there's quite little left to bloom in the garden.

Here are the 3 stages, flower, after-flower, seed.
