Sequoiadendron giganteum aka Giant Sequoia

Taxonomy

Genus Sequoiadendron Family Cupressaceae Order Pinales Class Pinopsida Phylum Tracheophyta
Sequoiadendron giganteum, commonly known as the giant sequoia, is a massive tree and the sole living species in its genus. It belongs to the family Cupressaceae and is one of three redwood species, along with the coast redwood and dawn redwood. Giant sequoias can be found naturally in groves on the western slopes of the Sierra Nevada mountain range in California. Unfortunately, the giant sequoia is listed as an endangered species by the IUCN, with fewer than 80,000 trees remaining. Recent destructive events, such as the Castle Fire of 2020 and the KNP Complex & Windy Fire in 2021, have further contributed to the decline of this species. Factors like fire suppression, drought, and climate change have made the giant sequoia severely threatened. Prescribed burns to reduce fuel load may play a crucial role in saving this species. The genus name "Sequoiadendron" is believed to be a tribute to Sequoyah, the inventor of the Cherokee syllabary, but an etymological study suggests that the name was actually coined by Stephen L. Endlicher, a linguist and botanist who corresponded with Sequoyah. The giant sequoia is a slow-growing evergreen tree with a pyramidal growth habit, reaching heights of approximately 25 meters. It has sharp, yellow-green leaves that turn grey-green as they mature and a distinctive reddish-brown trunk. The tree produces upright cones that hang down when ripe. Ideal for large parks or gardens, the giant sequoia requires adequate light, water, and fertilizer for optimal growth. It is hardy in USDA zones 6 through 9 and is not prone to significant pests or diseases. With proper care, it can add significant height and trunk width in just one growing season. These long-living trees can reach heights of up to 260 feet and live for more than 3,000 years. They thrive in areas with an annual rainfall of 4 1/2 to 6 inches and well-draining, moist soil.

How to care for Giant Sequoia

Difficulty

Giant Sequoia is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Giant Sequoia should be watered regularly, allowing the soil to dry out between waterings.

Soil

Giant Sequoia loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Giant Sequoia requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Big Tree will be sure to bring you many years of beauty and enjoyment.
