Native Azaleas

Rhododendron canescens (Mountain Azalea, Piedmont Azalea) is a pink-flowering native. Some are white with a pink blush while others have dark pink blooms. USDA zones 6-10; part shade, full shade to full sun with moist soil.

Rhododendron austrinum (Flame Azalea) is a flashy orange-flowering native. USDA zones 6-10; part sun to shade in moist soil.






All azaleas were photographed on April 26, 2009 by Freda Cameron at Sarah P. Duke Gardens on the campus of Duke University in Durham, North Carolina. There is no admission fee to visit these 55-acre public gardens in the Triangle area of Raleigh, Durham and Chapel Hill.

Cottage Garden Stroll

What's growing in the garden today? It seems that flowers are literally shooting up overnight or even within a few hours during the day.

The Knock Out® Roses (showing two of the seven bushes) and Spanish lavender are spilling through the cottage garden fence. I had to pull several lavender out of the cottage garden this year. Three large ones still remain and are looking very healthy. The clematis are loaded with buds. There's one bloom on the right side of the roses, but there will soon be a big display. Shades of purple companions stand back so that the strong cherry color of the roses can be the main attraction.

In the newly revised (last September) section of the cottage garden, a loropetalum provides dark foliage above volunteer petunias. On the far side, scabiosa 'Butterfly Blue' and Heliotropium amplexicaule 'Azure Skies' (creeping perennial heliotrope) are matched color partners. In the background, the magenta blooms of salvia greggii (autumn sage) and cosmos 'Sonata pink' are hiding from view.

I've added the heliotrope all along this side of the stream. It will bloom from now until frost in the fall without any deadheading. It has very long taproots, but can be transplanted (but you may find several offspring left behind). I purchase my heliotrope locally. The only online source that I've found is Santa Rosa Gardens, but I have never ordered plants from them.

The opposite bank of the stream in the cottage garden will soon be in bloom with dianthus 'Bath's Pink'. Following the pink phase, the daylilies, achillea, leucanthemum, gaillardia, angelonia, cosmos and zinnias will bloom in a color scheme of white, yellow and purple.

The Encore® Azaleas and iris x hollandica (Dutch iris) are blooming together along a path up to the cottage garden gable gate (that is covered with Lady Banks rose). Soon, the pink phlox paniculata 'Eva Cullum', blue platycoden, blue perennial geranium 'Brookside', and the lavender tones of perennial heliotrope will fill up this little section with more blooms. The geranium is showing one bloom this morning.

There are three more azaleas (in tree form) on the opposite side of the cottage garden. Those are underplanted with heuchera 'Purple Palace', phlox 'Robert Poore' and magenta impatiens with coleus.

Versatile Verbena Connects Companions

Verbena canadensis 'Homestead Purple' is a versatile perennial for months of great blooms. I have a mass planting growing on a slope in the butterfly garden where she serves as a pivotal plant surrounded by different companions.

Above the verbena, I grow bronze fennel as a host plant for butterflies. Verbena is also a great nectar plant for attracting butterflies and bees in the garden.


The light blue spring flowers of amsonia hubrichtii show up well with verbena as the backdrop on the slope.


From another view, the spires of salvia nemorosa 'Caradonna' mix with the spheres of the verbena in color harmony.


Right now, the companions provide cool colors. As the summer heats up, so will the color scheme as the yellow flowers of hypericum, orange flowers of echinacea and crocosmia as well as the red flowers of monarda begin to bloom.

Verbena 'Homestead Purple' likes full sun and well-drained soil in zones 6-9. This is a great ground-covering plant that looks good from spring until frost in my zone 7b garden. I have recently added this purple verbena along our guest parking area where the conditions are particularly hot and dry.

I like this verbena because of the long bloom season of purple that works so well with other perennials, annuals and shrubs. This verbena, planted in 2007, has been reliably deer and rabbit resistant. It is a relatively easy and inexpensive plant to find at garden centers and nurseries in my area.
