Sequoiadendron giganteum is a giant conifer reaching 250-300′ in the wild. Under cultivation in the eastern U.S. it usually does not exceed 60′. England, with its high moisture climate, has produced many specimens over 100′. Habit is pyramidal and dense in youth, with age the lower branches are lost, the crown remains. Pendulous branches of ‘Pendulum’ create an arching effect. Needles are bluish green, cones are 1 1/2-3″ long, reddish brown in maturity. The bark is fibrous, reddish brown. It suceeds better in the eastern U.S. than Sequoia sempervirens, tolerating drier conditions. Native to California’s Sierra Nevada Mountains at 4500-8000 foot elevation.Important Info : This is one of the largest conifers, reaching 250-300' in its native habitat.

FertilizingHow-to : Fertilization for Young Plants
Young plants need extra phosphorus to encourage good root development. Look for a fertilizer that has phosphorus, P, in it(the second number on the bag.) Apply recommended amount for plant per label directions in the soil at time of planting or at least during the first growing season.
LightConditions : Full to Partial Sun
Full sunlight is needed for many plants to assume their full potential. Many of these plants will do fine with a little less sunlight, although they may not flower as heavily or their foliage as vibrant. Areas on the southern and western sides of buildings usually are the sunniest. The only exception is when houses or buildings are so close together, shadows are cast from neighboring properties. Full sun usually means 6 or more hours of direct unobstructed sunlight on a sunny day. Partial sun receives less than 6 hours of sun, but more than 3 hours. Plants able to take full sun in some climates may only be able to tolerate part sun in other climates. Know the culture of the plant before you buy and plant it!
WateringConditions : Moist and Well Drained
Moist and well drained means exactly what it sounds like. Soil is moist without being soggy because the texture of the soil allows excess moisture to drain away. Most plants like about 1 inch of water per week. Amending your soil with compost will help improve texture and water holding or draining capacity. A 3 inch layer of mulch will help to maintain soil moisture and studies have shown that mulched plants grow faster than non-mulched plants.
PlantingHow-to : Planting a Tree
Dig out an area for the tree that is about 3 or 4 times the diameter of the container or rootball and the same depth as the container or rootball. Use a pitchfork or shovel to scarify the sides of the hole.
MiscellaneousGlossary : Specimen
A specimen can be a tree, shrub, ground cover, annual, or perennial that is unique in comparison to the surrounding plants. Uniqueness may be in color, form, texture, or size. By using only one specimen plant in a visual area, it can be showcased. Specimen plants are accents in the landscape, just as statues, water features, or arbors.
Glossary : Evergreen
Evergreen refers to plants that hold onto their leaves or needles for more than one growing season, shedding them over time. Some plants such as live oaks are evergreen, but commonly shed the majority of their older leaves around the end of January.
Glossary : U. S. Natives
Native plants require lower maintenance and usually have less pest problems. They are key components in the xeriphytic landscape and backyard wildlife habitat. Select your region and the search will look for all plants in the database that are native to your area.
