Sonata Dwarf Mix Cosmos

2 reviews

Sonata offers the same attractive foliage and lovely single blooms of the larger cosmos but the plants are under 2 feet tall. The mix includes a pristine white, a brilliant carmine red, a rose pink, and a unique bicolor with pink edges and the carmine at the center. A classic summer flower, the foliage is finely cut, and the plants branch out and bloom profusely and continually.

Sonata dwarf mix cosmos review.

It`s always a good experience buying from Pinetree. I get the Sonata mix every year. Great germination on these low maintenance tireless bloomers. A real nice variety.

I have never been able to grow cosmos from seeds. Maybe I just planted too early. At any rate these seeds all germinated and I have lovely Cosmos. The plants are assorted colors, busy and lovely in the garden. I credit Pine Tree seeds for the success.
