Groundcones often look at first glance like pine cones lying on the ground, especially when they are brown in color. They may also be shades of yellow, red, and purple. Each plant may be a few inches tall, and pine-cone-shaped or cylindrical.
The cones are broad, ovoid, 8–15 cm (3–6 in) long, and take 36 months to mature, longer than any other pine. The seeds ( pine nuts , piñones , pinhões , pinoli , or pignons ) are large, 2 cm ( 3 ⁄ 4 in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 4–8 mm ( 5 ⁄ 32 – 5 ⁄ 16 in ...
Zinnias are an annual plant usually grown in situ from seed, as they dislike being transplanted. Much like daisies, zinnias prefer to have full sunlight and adequate water. In the preferred conditions they will grow quickly but are sensitive to frost and therefore will die after the first frost of autumn.
Subfamily Piceoideae : cones are annual, without a distinct umbo, the cone scale base is broad, concealing the seeds fully from abaxial view, seed is without resin vesicles, blackish, the seed wing holds the seed loosely in a cup, leaves have primary stomatal bands adaxial (above the xylem) or equally on both surfaces.
The cones are stout and heavy, typically 8–15 cm (3.1–5.9 in) long and broad, and contain large, hard-shelled, but edible, pine nuts. [4] Like all pines, its needles are clustered into 'fascicles' that have a particular number of needles for each pine species; in the Torrey pine there are five needles in each fascicle.

Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae.Coulter pine is an evergreen conifer that lives up to 100 years. [2] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico, occurring in mediterranean climates, where winter rains are infrequent and summers are dry with ...
The leaves snap cleanly when bent; this character, stated as diagnostic for red pine in some texts, is however shared by several other pine species. The cones are symmetrical ovoid , 4–6 cm ( 1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long by 2.5 cm (1 in) broad, and purple before maturity, ripening to nut-blue and opening to 4–5 cm ( 1 + 1 ⁄ 2 –2 ...
