100 Chinese Houses Seeds Collinsia heterophylla Wildflower Pollinator Garden

Collinsia heterophylla, commonly called Chinese Houses, is an annual wildflower native to the western United States, prized for its distinctive stacked whorls of two-toned blooms that create a tiered, pagoda-like effect along each stem. It brings a soft, naturalistic charm to beds, borders, and meadow-style plantings and is a favorite for low-maintenance wildflower gardens.

This wildflower is well suited to cottage gardens, pollinator plantings, and informal landscapes, where its layered flowers rise above bright green foliage through spring and early summer. It performs best in cool-season conditions and self-sows readily where it is happy, returning year after year without replanting. Species: Collinsia heterophylla. Type: Annual wildflower.
