    Mix with Cosmos Carpet

    These are stunning. Planted along with Cosmos Carpet in planters and in extremely dry soil on an embankment that can't seem to retain moisture. These are incredible.

    Cheerful, Reliable, Long-blooming

    I bought my first pack of these years ago and have been pleased to see them self-sowing reliably every year since. They're not exactly subtle in color but they work with California poppies and nasturtiums that do well in my garden. Also provide nice pops of color at the edge of the field and between rows of veggies. Seed heads are spiky, easy to harvest after blooming.
