[MAIPC] Viburnum x rhytidophylloides

[Rod Simmons]

Hi John,

I'm finding the way overplanted Viburnum x rhytidophylloides to be more invasive than the much longer leaved lookalike V. rhytidophyllym.

I've now collected Viburnum x rhytidophylloides from D.C., Maryland (Montgomery County), and City of Alexandria and Arlington County in northern Virginia.

Both taxa, however, are still very rare, naturalized escapes - at least in the D.C. region at this point.  (I've got only one collection of V. rhytidophyllym from the D.C. region - in the City of Alexandria.)

Still, I list V. rhytidophyllym in the Non-Native Invasive Plants of the City of Alexandria, Virginia list and will definitely add Viburnum x rhytidophylloides to the next revision, along with Hydrangea quercifolia, which I've documented as invasive in Arlington County.

I also plan on including Viburnum x rhytidophylloides in my next Noteworthy Collections paper.

All the best,

Rod

Is Viburnum rhytidophylloides, commonly sold as the cultivar Allegheny viburnum, on invasive lists?

Anecdotal?
Lookalike to V rhytidophyllym, leatherleaf viburnum, which IS an invasive.

Thanks in advance.
