continued from page 29 and mahogany-red new growth in spring. Sited in welldrained soil, this shrub should be a plant to enjoy, as it never needs pruning. It’s a perfect addition to the shrub border. The common name, while odd, is in reference to an unfortunate trait of these plants. Dog-hobble comes from the circumstance that this plant is poisonous to mammals and when eaten causes a number of issues, including loss of balance. The toxin is found in the leaves, stems, flowers, and nectar and can be fatal, if enough is consumed. That said, for clients who have dogs that have a bad habit of eating plants in the landscape, this isn’t the plant for them. We have about a dozen of ‘Girard’s Rainbow’ at home and have never had any issues with our dog or cat in over 10 years. Conversely, the toxicity of these plants has an upside, as deer tend to leave them alone for the same reason that we don’t want to eat them.
A perfect place for this plant would be on the north side of a house where it will be in constant shade. Just be sure it doesn’t get too much wind. Once cultural conditions are ideal for this plant, there should be little issues with pest or disease. In the south, they get a fungal infection that causes spots on the leaves, but doesn’t seem to be as much of an issue in zone 5. Give this unique, broadleaf evergreen a shot in one of your upcoming jobs. If you pick the right spot, it will reward clients with year round beauty and zero maintenance needs.
