viburnums, birds, and the leaf beetle
I was planning on expanding the viburnums in my yard to include: V. nudum Winterthur, V. cassinoides, V. prunifolium, V. trilobum Alfred, and V. X Pragense.
However, all of the above are susceptible to the viburnum leaf beetle. I am in Maryland near Washington, D.C. and though it has not been reported here, it is only a matter of time before my yard is affected.
Therefore, with regards to my future viburnums, it appears that I should limit myself to the Cornell University's list of non-susceptible viburnums: V. bodnantense, V. carlesii, V. davidii, V. x juddii, V. setigerum, V. sieboldii, V. plicatum var. tomentosum, and V. rhytidophyllum.
The questions I have are:
1) Which of the non-susceptible viburnums (other than the V. davidii V. plicatum var. tomentosum, and V. rhytidophyllum, since I either already have them or it hasn't done well in my yard) are best for birds, specially as fall/winter food?
2) Does anyone know the susceptibility of V. X Chesapeake, and V. Conoy to the leaf beetle?
3) Any other non-susceptible viburnums for birds?
