The History Behind Professor Sargent Camellia

The professor sargent camellia traces its origins back to Japan. It was discovered as a chance seedling by Japenese nurseryman Riemon Saito in Tokyo around 1890.

Sargent was instrumental in introducing numerous Asian plants, including many types of camellias, to the United States in the late 1800s. He helped popularize camellias as ornamentals in America, so it was fitting that this show-stopping new red camellia cultivar bore his name.

Professor sargent camellia first arrived stateside in 1910 when it was brought from Japan to California. It quickly became a sensation among American camellia enthusiasts and remains one of the most acclaimed japonica camellia varieties today. It has stood the test of time thanks to its vibrant blooms, hardiness, and year-round beauty.

Growing Conditions for Professor Sargent Camellia

• Provide well-draining, acidic soil – Camellias like moist but well-drained soil, so incorporate organic matter to improve drainage. Aim for a pH of 5.0-6.5.

• Give average water – Water regularly after planting and the first year. Mature plants only need water during extended dry periods.

• Watch the frost – Protect plants from frost damage by choosing a sheltered location. Cover with fabric when freezing temps are expected.

• Mulch around the roots – A 2-4 inch layer of mulch helps maintain cool, consistently moist soil conditions.

• Feed in early spring and summer – Use an acidic fertilizer formulated for camellias. Stop feeding by mid-summer.
