1. What do you like most about gardening in your region?

One of the best parts about living and gardening in the Southeast is that most of us experience some seasonality. I love the ebbs and flows of the changes we go through in every gardening year.


2.What’s the biggest challenge to gardening in your region?

Understanding microclimates is by far one of the biggest challenges for gardeners in the Southeast. It takes years in some cases for home gardeners to understand how weather and different exposures in their garden play a role in what they are growing. And it is always changing!


3. What plant are you jazzed about in your garden right now?

Conifers are always one of my favorite categories of plants. However, I feel I get more and more enthusiastic about different broadleaf evergreen tea olives (Osmanthus spp. and cvs., Zones 6–11) every year. New cultivars are emerging, and people are starting to think more broadly about other species we utilize in the landscape. If you don’t know this plant, many are sweetly fragrant bloomers in the fall and are a great alternative to common holly (Ilex spp. and cvs., Zones 5–9).

4. What was the last plant you killed?

I am prone to not listening to other gardeners when they tell me things won’t grow. This has led to many misadventures in growing things such as giant gunnera (Gunnera manicata, Zones 7–10) or blue Himalayan poppies (Meconopsis betonicifolia, Zones 6–8). My latest miss was an attempt at growing red feathers (Echium amoenum, Zones 3–9), which I successfully germinated and planted in my spring garden. It didn’t last long once it fainted in the garden at the first sign of summer humidity.
