Cold climates often put a damper on the dreams of gardeners wanting exotic colors and a unique feel. If we've just described you, then Electric Lights™ Red Azalea (Rhododendron 'UMNAZ 633' PPAF) might just be exactly the answer you've been looking for.

Solid fire engine red blossoms appear each spring. Like the rest of the Electric Lights™ series, this azalea blooms with fervent energy that lasts and lasts.

You'll notice the ruffled petals lay on a bed of bright green leaves that create an eye-catching contrast. That is if you can tear your eyes away from the vibrant red long enough!

Are you convinced yet? We're ready to snatch these up ourselves!

Because it's such a giving plant, this deciduous shrub offers up a third season of interest. In the fall the leaves will turn bronze before retiring for the winter.

Cut a couple of branches and add them to your indoor flower arrangements. It'll look delightfully daring in your kitchen or living room. Not to mention the blossoms smell oh so good!

There won't be a person walking by who won't stop to admire the brilliance of this Azalea. Hummingbird lovers might also be surprised with a visit from their favorite fluttering bird as well.

Electric Lights Red Azalea will have you checking the garden every single spring morning waiting for the profusion of scarlet to cover the shrub from top to bottom. Order one to be the next statement piece in your garden today!

How to Use Electric Lights Red Azalea in the Landscape

Let's get one thing clear, as long as this azalea is visible, there is no wrong place to use it in your landscape design-wise. We promise!

Plant a line of them as a border to your gardens and yards. In the spring they'll offer up a show you won't soon forget and for the remainder of summer, they'll make an attractive screen or hedge.

Pair with other plants that don't have a lot of spring color themselves. It'll be hard for them to compete with the excitement of Red Azaleas blooms. Instead, consider mixing it with boxwoods or Butterfly Bushes.

By itself, it's hard to beat this hardy shrub as a centerpiece in your island plantings or patio gardens.

Its size will also make it a great back row plant for your perennial gardens. As the other flowers show off in the summer, Red Azalea will stay a steady green.

#ProPlantTips for Care

Unlike some azaleas, Electric Lights Red Azalea isn't bothered by the cold very much. It's been known to shrug off -30 degree temperatures and come back better than ever.

The secret to keeping this bush happy is simple. Find it a place where it can bask in the sun all day long and leave it be. It'll also tolerate part shade though if that's what you've got, it's not too picky.

Slightly acidic soil is best and would be much appreciated by your plant.

Consider adding a layer of mulch around the base as well. This does a number of things like keeping the roots cool, keeping moisture even, and conserving water throughout the hottest parts of the year.

Mulch has the added bonus of making any garden you use it in look that much better!

If you'd like to take a bit of size off, go ahead and grab your shears right after the flowers are done for the season. That way you don't disturb next year's blooms.

This isn't the kind of bush that stays in stock for long. Order yours today before you have to wait another growing season!
