Northwest Plant Evaluations: Plant trials and the results - Neil Bell, Community Horticulturist, OSU Extension

In 2000, Neil Bell began research to identify a palette of shrubs suitable for low-input, un-irrigated landscapes in the Willamette Valley. Since 2000, he has conducted many studies of landscape plants for drought tolerance and cold hardiness, collaborating with Heather Stoven.

Studies on Ceanothus, Halimium, Hebe and Grevillea have concluded and results continue to inform the nursery industry and home gardeners in plant selection.  Neil is currently evaluating 75 selections of Arctostaphylos (Manzanitas).

Neil’s method for evaluation is harsh by home garden standards—plants are not watered, sprayed or pruned for the duration; they are rated for growth, flowering and hardiness. The goal is to provide information on plants suitable for “low-input” landscapes in the Willamette Valley and other areas west of the Cascade Mountains.

Since 2000, Neil Bell has overseen the Community Horticulture program in Marion County and Polk County, which includes the Master Gardener program.  Among his significant contributions to the Statewide Master Gardener Program are training on diagnosis of plant problems and pruning of ornamental plants. He has co-authored publications on water-efficient landscape plants, soil amendment and mulch use. Neil lives and gardens with his family on 5 acres west of Monmouth.


Clackamas County Master Gardeners are the folks who put on the annual Spring Garden Fair, bringing together over 7,000 gardeners with over 150 plant and garden-art vendors.
