Princeton Sentry® Ginkgo Tree

Princeton Sentry® Ginkgo (Ginkgo biloba ‘Princeton Sentry’) is a living fossil — the Ginkgo species has existed virtually unchanged for over 200 million years, surviving ice ages, mass extinctions, and the atomic bomb at Hiroshima, where Ginkgo trees were among the first living things to re-emerge from the devastation. Growing one is planting a direct connection to the ancient world. This male selection delivers all the Ginkgo’s legendary ornamental qualities — the distinctive fan-shaped leaves, the brilliant simultaneous golden-yellow fall color drop that carpets the ground in a single spectacular event — in a tight, columnar form without the notorious malodorous fruit of female trees. Cold hardy to Zone 3, virtually pest and disease free, and adaptable to an extraordinary range of soils from pH 5.0 to 8.0.

The Simultaneous Golden Drop — Ginkgo’s Most Spectacular Moment

No other tree puts on quite the fall display that Ginkgo does. The fan-shaped leaves hold their brilliant golden-yellow color through late fall — often the last tree still fully leafed while everything around it has gone bare — and then, in one of nature’s most dramatic single events, they drop almost simultaneously, blanketing the ground in a perfect circle of gold beneath the tree. That visual moment is something people who witness it remember for years. Princeton Sentry® delivers it in a tight, columnar form ideally suited to street plantings, tight urban spaces, and landscapes where a broader spreading canopy won’t fit.

200 Million Years Old — A True Living Fossil

Ginkgo biloba has no close living relatives and represents an entire division of plant life that once covered the globe. The trees that survived Hiroshima’s atomic blast in 1945 — four Ginkgo trees within a mile of the hypocenter — were budding again the following spring while the surrounding landscape was devastated. The species' extraordinary resilience is not mythology; it’s documented botanical history. Planting a Princeton Sentry® Ginkgo is an act that connects your landscape to that unbroken 200-million-year lineage.

Male Selection — No Messy Fruit

Princeton Sentry® is a male Ginkgo selection, meaning it produces no fruit — a significant practical advantage. Female Ginkgo trees produce seeds enclosed in a fleshy outer coating that releases an infamous odor when it falls and decomposes. Princeton Sentry® delivers the full ornamental value of the species with none of that maintenance concern.

Urban Tough — Wide Soil Adaptability

Ginkgo’s urban tolerance is legendary — compacted soils, pollution, drought, heat, salt spray, and the full range of urban stresses leave it largely unfazed. Princeton Sentry® thrives in soil pH from 5.0 to 8.0, adapts to loam, clay, and sandy conditions, and performs reliably from Zone 3 through Zone 8. Few trees combine this level of toughness with this level of ornamental distinction.
