Sequoia is a genus in the cypress family Cupressaceae, containing the single living species Sequoia sempervirens. Common names include Coast Redwood and California Redwood. California native. It is one of the largest trees of the world. Fast growth when it is young. It can reach height of 40 m. to 60 m. This tree stands straight up, hurled, pyramidal with horizontal to slightly drooping branches. The summit is narrow and round. The tree is deprived of branches on a third or half its height. The sequoia has a very broad trunk (9 m diameter). It has thick bark (15 - 30 cm), fibrous and crevassed, of a red-orange color, and a flexible, spongy texture. The wood, of excellent qualities, deprived of resinous channels, is imperishable. It resists well to insects and fires. It is used in joinery. An adult tree produces more than 1.000 m ³ of wood. The leaves are laid out on the secondary branches in two rows of long flattened needles. They are green on top and blue-white bands below. The leaves of the principal branches are scale-like. The foliage is persistent and aromatic. The tree is monoic. The male flowers ( 2 mm), are in the shape of yellowish droplets and the female flowers are in a narrow and greenish cones ( 4 mm). Flowering takes place in winter (February but they where on the tree since last autumn). It has tiny inflorescences at the end of the short branches. The seed cones are ovoid, 15-32 mm long, with 15-25 spirally arranged scales; pollination is in late winter with maturation about 8-9 months after. Each cone scale bears 3-7 seeds, each seed 3-4 mm long and 0.5 mm broad, with two wings 1 mm wide. The seeds are released when the cone scales dry out and open at maturity. The pollen cones are oval, 4-6 mm long. Hardiness zones: 8-10 (-10°C/ 15°F, 1°C/ 35°F) in winter. The Sequoia needs a deep, fresh, not very calcareous ground and well-drained well (acid or neutral, fertile). It adores the sun and a sheltered place. This tree requires much water. It also needs a certain atmospheric humidity. Be careful, the growth and young plants are frost-susceptible spring.

Germination Before sowing, you need to cold stratify the seeds for about 3 months. Then lay the seed on top of the moist compost, pressing it firmly so that it makes perfect contact with the soil. Do not push them down too hard. Keep the compost at 20°C, and under reduced light. But be aware! The seeds are quite susceptible to drought. You can put a glass plate or some plastic foil over the pot, but you have to be careful not to kill them by making things too wet. Small germinated sequoias die rather easy because of over-watering. It's a very sad thing to see a baby sequoias wither away! Sequoia sempervirens seeds will usually germinate in 7-60 days, but even under good conditions germination may be erratic. Don't think things will not work out: patience is a virtue!
Scarification / Stratification This will break their dormancy. It creates a cold and moist environment for the seeds. Mixed in seeds with slightly moistened vermiculite or peat, only damp in a ziplock bag. Close zip bag shut and store it in the salad crisper compartment of your refrigerator. If any seeds begin to sprout during the cold stratification, simply remove the seed and plant.
