I am teaching a course at Palm Beach State College in Boca Ratone called 'Color in the Garden'. Here's some of the pictures I used in the talk.
Warm Colors - Daylilies and Coreopsis from my garden in Maine. What a cheerful sight.
Coneflowers and Black-eyed Susan's from my garden in Maine. They go well together because they are a similar shape. Pink shows up well in front of a grey fence.
Golden dew drop tree has beautiful blue flowers followed by gold berries. Underplanted with blue lobelia and white osteospermum daisy like flowers and euphorbia 'diamond frost'. Looks great in a white planter
by a white fence. Both Mom and I bought the tree here in Florida.
Yellow allamanda and pink bouganvillea - a surprisingly pleasing color combination.
A monochromatic color scheme - 2 shades of purple petunias
