Surprisingly Tasty Ornamentals Hide in Plain Sight

I’m always pleased when I discover beautiful ornamental plants in my garden that are also delicious to eat. So, last month, at a Hardy Plant Study Weekend in Portland, OR, I was happy to attend a presentation by Stacey Hirvela called “Incidentally Edible.” Stacey is a marketing specialist for Proven Winners Colorchoice Shrubs, and the […]

Historic Gardens—What the past tells us about today—and tomorrow

I love the feeling of time travel that comes with visiting restored gardens. One of my favorites is Aspet—a garden designed around the home of artist and sculptor, Augustus Saint-Gaudens (1848-1907). The 30-acre garden and 200-acre grounds are now a National Historical Park in New Hampshire. When I visit gardens like this, one question always […]

Indian Shot with bright flowers

Indian Shot or Cannas are happiest in frost free greenhouses or a conservatory, they can even go outside all summer. But their lush foliage and incandescent blooms look better for longer under cover where their tropical appearance also seems more appropriate.
