Hi Pamela,
From the University of Massachusetts:
“A selected list of resistant trees and shrubs include: apple/crabapple (Malus), beech (Fagus), birch (Betula), boxwood (Buxus), dogwood (Cornus), hackberry (Celtis), hawthorn (Crataegus), hickory (Carya), holly (Ilex), honeylocust ( Gleditsia triacanthos), katsura (Cercidiphyllum), linden (Tilia), mountain-ash (Sorbus), oak (Quercus), pear (Pyrus), aspen/poplar (Populus), sycamore/planetree (Platanus), sweetgum (Liquidambar) and walnut (Juglans). All conifers are also resistant or immune to Verticillium wilt. Resistance does not imply immunity; therefore some of the plants listed here may be susceptible to infection.”

Note that being resistant doesn’t guarantee that a plant won’t get verticillium wilt. It just means it’s less likely to get it.
Good luck.
