The Russian Sunflower (Helianthus angustifolius) is a very valuable plant for the garden because itblooms in the fall. It mixes well with ornamentalgrassesbecause it likes full sun and tolerates poor soil and dryness.
The flowers are like small daisies in large clusters at the top of a 6′ – 8′ plant so it is good for a background in the perennial garden or growing among grasses.
Helianthus angustifolius ‘Mellow Yellow’ is a lighter colored variety
At the end of November when it is finished blooming and the foliage is browning, we cut back the plant clear down to the soil.
After the plants are cut back the grasses become more visible for the winter.
The plants can be cut back in July to keep them from getting this tall and falling over in the rain.
