A big ol’ heapin’ tablespoon of California Poppy seeds mixed with rice hulls (for ease of scatter & spacing).

Eschscholzia californica.

Perennial plant that loves full sun. Sow in late fall to overwinter as a spring bloom or in early spring as poppies can handle light frost. Will blossom in summer from seed if watered well during initial growth. Drought tolerant, but plants like water to get started. Allow spent flowers to form pods and drop seeds for the following year.
