|I have a two tiered terrace flower garden, I have placed lorepedalum hedges on top and so far I have two catus plants on the bottom level.I am stumped, what plants would compliment these plants. I get morning to midday sun on top terrace but all day sun on the lower level.|
|In the full sun area, consider Black Eyed Susans (Rudbeckia). They like full sun, dry or even arid conditions, and soil that is not overly rich. They can spread and fill an area if that's what you need, and they bloom almost all summer long. Purple Coneflowers [Echinacea purpurea] are not as invasive as the Rudbeckia they resemble, but they're every bit as tough - and are beautiful summer flowering perennials. 'May Night' Salvia is a small, clumping plant with spikes of purple-blue flowers. They grow in full sun or part shade so can be used on either tier. Sedums, or stonecrop are perfect for a sunny garden. They have fleshy, succulent leaves and most bloom in the summertime. Coreopsis is another sun-loving suggestion.
For part-sun, consider Japanese Anemone, Astilbe, Bergenia, hardy Begonia, fringed bleeding heart (Dicentra eximia) or Colombine. All will burst with color over the summer season.
Enjoy your garden!
