Platanus occidentalis Seeds | American Sycamore
LATIN NAME: Platanus occidentalis
COMMON NAME: American Sycamore
Plant Profile
American Sycamore (Platanus occidentalis) is a tree. American sycamore is a tall, bold, mottled-bark tree of river banks and flood plains, and its great, broad, maple-like leaves and pale, mottled, peeling bark have made it a familiar of countryside for a very long time. Tall, open tree carries large, broad, three-to-five-lobed leaves and round, hanging, ball-like fruit heads through the winter. Bark peels away in pale, mottled plates, giving trunk a fine, curious, patchwork look. Its appeal to pollinating insects adds a second, ecological layer to its ornamental one. Each of these traits is modest on its own; together they make a garden-worthy plant.
Science & Biotechnology
As part of the Platanus group, Platanus occidentalis contributes to research on plant classification and adaptation, while nurseries and gardeners continue to trial it for cultivation. American sycamore has a strong and well-documented place in plant science, and it has been studied for its fast growth, its mottled bark and its place along rivers and flood plains. With present-day seed handling, raising this species well within the reach of any careful grower.
Uses & Benefits
American Sycamore works well in borders, containers and dedicated beds. American sycamore is grown for fast shade and mottled bark. Great, broad leaves make a fine, generous shade through summer, and pale, mottled, peeling trunk is one of the most curious and handsome of the tree barks. Round, ball-like fruit heads hang through winter as a fine feature, and tree is a dependable, easy grower for large garden, park and river bank. Getting it going is easy; keeping it going is easier still.
Plane trees are the great city shade trees; their bark had folk astringent use, and their London-form tolerance of pollution is legend.
Growing from Seed
Raising American Sycamore from seed is straightforward. Sow evenly over the surface and cover lightly into a loose, well-drained seed compost, water in gently, and keep the sowing in bright light with steady moisture. A cool, moist period before sowing helps the seeds wake evenly — a few weeks in damp medium in the refrigerator is the usual approach. Prick the seedlings out once they are large enough to handle, grow them on in bright light, and plant out when conditions allow.
Our Take
Few garden plants carry such a documented history of use as this one does. Within its genus it stands out for garden reliability. A few weeks of cold, moist stratification before sowing mirrors its natural cycle.
