The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots. The seed cones are ovoid or oblong and 25–40 mm long. The cones have 10–14 scales, which are green at first and mature to brown about 20–24 months after pollination. The male cones are 3–5 mm long and release highly allergenic pollen in late winter.
The Paiute cypress grows in a small area of the Southern Sierra Nevada, within Kern County, California and Tulare County. It is found on soils of granitic origin at altitudes of 3,000–6,000 feet (910–1,830 m). It is found in pinyon/juniper and oak/pine woodlands, chaparral, and closed-cone-cypress forest habitats. [2]
Inside the cone are approximately 70 to 100 seeds, brown with a light waxy coating described by botanists as glaucous. [3] [10] The seeds are much larger than those of other western cypress trees, weighing two to seven times as much. [4] Closed, but already ripe, cones still on the trees will also open after being exposed to the heat of a fire ...
In general, lemon cypress trees won’t need to be fertilized at all, but if your plant looks like it needs a pick-me-up, fertilize it just once a year in early spring with compost or a diluted ...
The seed cones are globose to oblong, 10–20 mm long, with four to 10 scales, green at first, maturing brown or grey-brown about 25 months after pollination. The cones may either open at maturity to release the seeds, or remain closed for several years, only opening after the parent tree is killed in a wildfire , allowing the seeds to colonise ...
Close up of Santa Cruz cypress seeds. The reproductive age of the Santa Cruz cypress is on average 11 years of age. Seed viability falls to 10 percent by the time a tree is 30 years old. [8] Like some other coniferous trees, the seed-bearing cones of the Santa Cruz cypress depend on fire to heat open the cone and release the seeds. The fires ...
The seed cones are oblong-ovoid to cuboid, 15–25 mm long and 13–20 mm broad, with six (rarely four or eight) scales, each scale bearing a prominent umbo; they are strongly serotinous, not opening to release the seeds until the parent tree is killed by wildfire. This enables heavy seed release to colonize the bare, fire-cleared ground.
Hesperocyparis forbesii reaches 10 metres (33 ft), and is usually without dominant terminal shoot resulting in a multi-trunked tree. The foliage ranges from rich light green to green, and seed cones are dark brown, measuring 20–32 mm. [3] Hesperocyparis forbesii - Tecate cypress bark, at Guatay Mountain, Cuyamaca Mountains
