'Brandywine Sunset' , with large soft yellow flowers with a pink blush, belongs to a group of hardy, single-flowered chrysanthemums sometimes called Korean mums. In the Midwest, this is an excellent selection if you want a hardy, long-blooming mum that will finish the bloom season in October, continuing until a hard freeze. In our trials, this one was the most attractive to monarch and red admiral butterflies. Honeybees love them too.
