Floral Illustrations of the Seasons / Consisting of the Most Beautiful, Hardy and Rare Herbaceous Plants, Cultivated in the Flower Garden

This is perhaps one of the most desirable species of the genus Helianthus, from the brilliancy of the colour and its moderate growth. It makes a striking appearance when planted at the back of the flower borders, and will continue in beauty to a late period in the autumn. According to Pursh it is found in the "western parts of Pennsylvania," and was introduced into this country in 1732. It will grow well in any good garden soil, and may be increased by parting the roots. There are not many species of this genus suitable for a flower garden, as they grow to such a large size, and take up so much room: the best are
