Q: How is 'Roberts' different from the native Western Sycamore (Platanus racemosa)?
A: 'Roberts' is a selected cultivar chosen for two primary improvements: 1) More deeply lobed leaves that are more ornamental and less coarse than the species. 2) More heavily exfoliated barkwith enhanced contrast and color variation, creating a more striking winter display. It may also have a slightly more compact, manageable mature size (45-50 ft vs. the species' potential 70-100+ ft).

Q: Does it get anthracnose or other diseases?
A: Western Sycamores can be susceptible to anthracnose, a fungal disease that can cause leaf blight in wet springs. 'Roberts' shows improved resistance compared to London Plane trees, but in very wet years, some leaf drop may occur. This rarely harms the tree long-term. Good sanitation (raking and disposing of fallen leaves) helps reduce recurrence. It is not as susceptible as American Sycamore.

Q: How much water does it need?
A: As a riparian native, it naturally prefers consistent moisture. However, once established (2-3 years), it exhibits good drought tolerance. For best growth and dense foliage, occasional deep watering during dry periods is recommended, especially in hotter inland climates. It will survive with less but may drop leaves earlier in summer drought.

Q: Is it messy? Does it drop a lot of leaves or seed balls?
A: It is a deciduous tree, so it drops all its leaves in late fall/early winter. It also produces the characteristic spherical, bristly seed balls that persist into winter before gradually falling. While not considered excessively messy, these seasonal traits should be considered when siting the tree near patios, pools, or pristine lawns. The winter bark display more than compensates for the minimal seasonal debris.

Q: Can it be planted near structures?
A: With a mature spread of 35-40 feet, it requires ample space. Plant it at least 20-25 feet away from buildings, walls, or large hardscape areas to accommodate its eventual width. Its roots are strong and can be invasive near foundations, sidewalks, or sewer lines if planted too close. Give it room to thrive.
