Why Plant Gibraltar Exbury Azalea?

Construction-zone orange never looked so inviting! Gibraltar Exbury Azalea is a sassy Accent with blooms that are outrageously, gorgeously, fantastically ORANGE. People in passing airplanes will look down in wonder and amazement. Unfurling in late spring, the big, ruffled blossoms cover the branches and the newly emerging foliage, making it look as if the whole plant is on fire. The warm orange glow is just the thing to wake up your mixed borders, patio plantings, or woodland edges. Be careful about planting it in your front yard—a traffic jam may ensue when passersby get a glimpse of these bodacious blooms!

Deciduous Azaleas are the showboats of late spring, decadent Accents that offer delightful, funnel-shaped flowers in a rainbow of colors. Many of these are hybrid selections, carefully bred from among several different species from Asia and America. Gibraltar Deciduous Azalea is one such hybrid Azalea. Gardeners have enjoyed it since 1947. Legendary British plantsman Anthony Waterer made the initial cross at his Knap Hill Nursery. Edmund Leopold de Rothschild of Exbury further developed the plant, and Gibraltar is now usually called an “Exbury Hybrid,” even though that is only half of the story.

But wait, there’s more! Many Deciduous Azaleas supply not only sensational spring flowers but also striking fall color, and Gibraltar is no exception. When nights turn frosty, this star takes the stage again, putting on a brilliant show of gold and orange foliage.

How To Plant Gibraltar Exbury Azalea

Deciduous Azaleas aren’t hard to grow, but it can be a little tricky to keep them looking sharp throughout the season. One issue they have is powdery mildew, which doesn’t kill the plant, but leaves a white film on the foliage. Gibraltar Exbury Azalea shows good resistance to powdery mildew. To further guard against this affliction, provide your plant with the best possible growing conditions. Avoid extremes—give it good light but no hot afternoon sun, moist but not soggy soil, good air circulation but no strong winds. In addition, the soil should be rich with organic matter, well-drained, and acidic. Mulch to conserve moisture.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box!

*For Big trees and Shrubs, Size XL and bigger: Review our Seasonal Shipping Timelines and Policy here.

Your trees and plants are grown across the United States at various Bower & Branch Growers. Depending on your location, your plant orders may be shipped from various locations. Please expect orders with multiple items to be delivered over a number of days as a result. Orders made up of numerous items or selections will not arrive at your home on the same day.

Shipping Delays:

From time to time, Bower & Branch Growers may determine to delay order shipment based on various factors for plant health. Weather in your region, as well as, where your plants are grown, is always considered when shipping. Extreme weather conditions may delay some or all of your order. Bower & Branch allows our Growers to make final shipping decisions based solely to benefit your trees and plants’ health and success.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
