| Seeds of most hardy perennials, including bleeding hearts, columbines, phlox, and primulas, require a period of chilling to germinate. |
| Peonies, irises, daylilies, and delphiniums peak as phlox come into bud and astilbes begin to light up shady garden spots. |
| Spring-blooming wildflowers are the broad-leaved spiderwort, downy yellow violet, and hairy phlox. |
| Creeping phlox, thyme and aubrietia grow between terrace stones, in typical English fashion, next to a creeping bent lawn. |
| The beds burst at the seams with summer phlox, Shasta daisies, coneflowers, and 75 varieties of daylilies. |
| Bright red salvias, phlox, anthurium and balsam flower in profusion in neat rows, and no wonder Thangam won the first prize for her garden. |
