Sequoia sempervirens 'Mt. Loma Prieta Spike' / Mt Loma Prieta Spike coast redwood

Sequoia sempervirens Mt. Loma Prieta Spike is a strongly growing, robust, upright weeping selection of coast redwood with a dominant central leader and cloaked (weeping) lateral branching. After 10 years of growth, a mature specimen will measure 20 feet (6 m) tall and 6 feet (2 m) wide, an annual growth rate of 2 feet (60 cm) or more.

While superficially similar to Sequoiadendron giganteum ‘Pendulum,’ this conifer has less of a meandering growth habit; it grows straight skyward, creating stunning exclamation point in the landscape.

This cultivar originated as a natural mutation selected in the late 1980s by Allan Korth, a former nurseryman from the vicinity of Santa Cruz, California. He named the plant around the time of the Mt. Loma Prieta earthquake and its notable “spike” in the Richter scale. He is thought to have found the mother plant in near the epicenter near Mt. Loma Prieta peak in the Santa Cruz mountains.
