Twenty-nine herbaceous perennial ornamentals were evaluated for root g
alling after 2 months in soil infested with Meloidogyne hapla under gr
eenhouse conditions. Plants such as Asclepias, Epimedium, Liriope, Lit
hospermum, Myosotis, Penstemon, Sidalecea, and Solidago did not have g
alls or egg masses present on the root system and were rated as resist
ant. Astrantia, Boltonia, Centranthus, and Miscanthus had more than 10
0 galls on the roots (similar to 'Rutgers' tomato controls) and were r
ated susceptible. The remaining plants were intermediate in response.
The identification of additional M. hapla-resistant perennial ornament
als will aid in nematode management in nurseries and landscapes.
