The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name "cone" derives from Greek konos (pine cone), which also gave name to the geometric cone.
The male flower head may be yellow or burgundy red, is cone- or egg-shaped, 8–19 cm (3.1–7.5 in) long, hardly about 1 + 1 ⁄ 4 cm (0.49 in) across, subtended by an involucre of several leaves of about 1.9 cm (0.75 in) long that are often covered in rusty-coloured soft hairs.
The female cone then opens, releasing the seeds which grow to a young seedling. To fertilize the ovum, the male cone releases pollen that is carried in the wind to the female cone. This is pollination. (Male and female cones usually occur on the same plant.) The pollen fertilizes the female gamete (located in the female cone).
It is a dioecious species, with male and female structures on separate plants. The male cone is brown with spiralling scales and measures 5 to 15 mm (0.20 to 0.59 in) long by 3 mm (1 ⁄ 8 in) wide. It grows from the leaf axils. The female cone has one scale bearing one seed about 1 to 2 cm (0.39 to 0.79 in) long.

Female (seed) cones are globular, 8–13 cm across, and are borne on short woody stalks. The majority of the cone crop matures early to mid February, as the cones turn brown and release the winged seeds , which are small, flattened, and attached to a wing about 3.5 cm in length.
Moses Cone's vacation home Flat Top Manor was located in nearby Blowing Rock, North Carolina, and the Cone sisters often visited their brother there. [ 6 ] [ 17 ] Other visitors included Julius Cone – another of the Cone siblings – and his wife Laura, who was an alumnus of the University of North Carolina.
