Eschscholzia Californica, Orange
http://plants.usda.gov/java/profile?symbol=ESCA2
The California poppy (Eschscholzia californica) is native to grassy and open areas from sea level to 2,000m (6,500 feet) altitude in the western United States throughout California, extending to Oregon, southern Washington, Nevada, Arizona, New Mexico, and in Mexico in Sonora and northwest Baja California.
It can grow 5–60 cm tall, with alternately branching glaucous blue-green foliage. The leaves are ternately divided into round, lobed segments. The flowers are solitary on long stems, silky-textured, with four petals, each petal 2-6 cm long and broad; their color ranges from yellow to orange, and flowering is from February to September. The fruit is a slender dehiscent capsule 3-9 cm long, which splits in two to release the numerous small black or dark brown seeds. It is perennial in mild parts of its native range, and annual in colder climates; growth is best in full sun and sandy, well-drained, poor soil.
It grows well in disturbed areas and often recolonizes after fires. In addition to being planted for horticulture, revegetation, and highway beautification, it often colonizes along roadsides and other disturbed areas. It is drought-tolerant, self-seeding, and easy to grow in gardens. It is also pictured in welcome signs while entering California.

poinsettia

When the leaves have fallen (usually by late March or early April), cut the Poinsettia back to about 8" in height. Continue a regular watering program, and fertilize your plant with a good, balanced. By the end of May, you should see vigorous new growth. Transplant the Poinsettia into a larger pot (no more than four inches larger than the original pot).
Continue regular watering during the growth period, and fertilize every two to three weeks. Once all chance of frost has passed and night temperatures average 55° F or above, you can put the Poinsettia outside (being sure to bring it back in if there's any chance the temperature will fall below 50° F)! If pruning is necessary to keep the plant bushy and compact, be sure pruning is done by September 1.
Then comes the hard part; complete light control. From October 1, the Poinsettia will need to be kept in complete darkness for 14 continuous hours each night. You’ll have to cover the plant with a black polythene bag or a large box, as any stray light, such as that of a streetlight or lamp, can stop the re-flowering process.
In the daytime, from October through December, the plant will need 6 - 8 hours of bright sunlight daily, with night temperatures between 60 - 70° F. Temperatures outside of this range can also delay flowering.
Following this regime faithfully for eight to ten weeks should give you a flowering Poinsettia for the Christmas season; the actual bloom time will depend on the particular variety.
