|discussion=<p><i>Helianthus mollis</i> is introduced in Ontario and adventive in the eastern United States (e.g., Maine), where it is continuing to spread, particularly along roads. Natural hybrids between <i>H. mollis</i> and <i>H. occidentalis</i> have been named H. cinereus Torrey & A. Gray (R. C. Jackson and A. T. Guard 1957); they differ from <i>H. mollis</i> by having smaller heads with fewer ray florets and narrower leaves with cuneate bases. Hybrids of <i>H. mollis</i> with <i>H. giganteus</i> have been called H. doronicoides Lamarck (Jackson 1956).</p>
