Powerfully Purple Blooms

Does your landscape need a little pop of extravagance and passion? People love purple flowering plants for their sense of luxurious, grounded creative energy.

And does this plant deliver. Get a quick fix for glorious magenta color with the Herbert Azalea (Rhododendron x 'Herbert'). One of the incredible Gable Hybrids produced by Mr. Joseph Gable, this flowering semi-evergreen selection is very dependable and cold hardy.

But it’s the large, vibrant blooms that will stop you in your tracks. They are simply magnificent and grow in a double layer called hose-in-hose, which gives the blooms twice the impact.

Mr. Gable himself wasn’t quite sure how to describe the color. He just knew he liked it, and that it really appealed to people. We’ll call them magenta and you can see for yourself that they are absolutely stunning.

This lovely plant will win over your neighbors and improve your garden's ecosystem. Its large blooms attract butterflies and hummingbirds. And its bright green foliage will show off its bountiful blooms.

Enrobe your woodland garden by simply planting several Herbert Azaleas in areas that seem to lack color or personality. This plant will also thrive at the edge of the woods where it will keep the local hummingbirds busy.

If you want to be the talk of the town, you can use the Herbert Azalea as a hedge along your property edge. Because it performs well in partial shade, this plant will also make a great hedge beside your fence or around your pool or patio.

You'll want to plant your Herbert Azalea in well-drained, acidic soil for its best performance. They naturally prefer to grow in a mound or mountain of soil. You can achieve this mounding-effect by planting them in a shallow hole and leaving several inches of the root ball above the ground. Then cover up the roots while avoiding the stem with a thick layer of pine mulch.

Bring excitement to your yard with the Herbert Azalea. You’ll add color and elegance to your garden with its frilly, hose-in-hose flowers.

You deserve this magnificent plant, order today!
