How are the heights measured?

All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.

What is a gallon container?

Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.

How does the delivery process work?

All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!

Why are some states excluded from shipping?

The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.

About Me


The Autumn Royalty Encore™ Azalea will fill your garden with beautiful rich purple blooms from spring to fall, unlike traditional azaleas, that only bloom in spring. This amazing bush will grow to be 4 feet tall and the same across, making a perfect backdrop to other smaller shrubs and flowers in your garden. As soon as the blooms of spring fade, new shoots will grow, carrying more flowers, and this will continue throughout summer and fall, right up to the arrival of cold weather. It grows well from the cool winters of zone 6 into the hot, humid summers of zone 9, and thrives in more sun than other azaleas can take. Plant around your home, on the north or east sides, or among shrubs in the partial shade of deciduous trees. This ever-flowering shrub is evergreen too, so even in winter it still has an attractive form and rich green coloring.

  • Beautiful repeat-flowering evergreen azalea
  • Smothered in rich purple blooms month after month
  • Continuous display from spring to fall
  • Thrives in sun or partial shade
  • Perfect garden specimen with no special care needed

Plant your Autumn Royalty Encore Azalea in soil that is slightly acidic. If your neighbors are growing azaleas, you can too. Even if your soil is not acidic, you can use special products called chelated iron to grow them in ordinary soil. You do not need to prune or trim your bush to have lovely dense growth and a rounded form, and this plant is free or any serious pests or diseases. It has been selected to be strong, hardy and easy to grow, so everyone can enjoy delicious purple blooms in their gardens for months on end with this beautiful and easy-to-grow plant.

Encore Azaleas took the gardening world by storm when they were first introduced, and today they remain the number one choice for everyone who loves azaleas. It is not just that they have beautiful colors and big, bold flowers – after all, so do many azalea varieties. What makes these plants stand out is their continuous flowering, from that first flush of spring right through summer and into fall with additional flower clusters constantly forming. These plants have transformed azaleas from ‘once a year’ flowers to ‘three season’ flowers and brought masses of color to many, many gardens.

Growing Autumn Royalty Encore Azaleas

The Autumn Royalty Encore Azalea stands out as one of the very best of these great plants. Don’t take our word for it, the south-east chapter of the American Rhododendron Society declared it Azalea of the Year in 2004, the year it was released by the breeder. This stunning beauty has large blooms 2½ to 3½ inches across, in the richest shades of purple that will steal your heart away. It has evergreen leaves that are a little larger than typical azaleas, and it grows into a substantial shrub, reaching 4 feet tall in just 10 years.


It is upright, but as wide as it is tall, so this is the perfect background shrub for shorter shrubs and flowers. In spring it will be covered all over with a dense display of blooms, making a grand center-piece in your garden. Then, as soon as the flowers fade, new shoots appear, and these develop more flower buds, continuing to bloom throughout summer and fall, only ending with the arrival of the colder weather. During winter your plant will be an attractive evergreen bush, but for the rest of the year it will be in bloom. This is very different from traditional azaleas, which are only in bloom for a few weeks, and are a plain green bush for the rest of the year.

Sun Exposure

The other great advantage to the Autumn Royalty Encore Azalea is its ability to grow well in sun. Most azaleas need soft shade all day, or they will burn and not develop well. The Encore Azaleas love sun, especially in the morning, but in cooler areas in the afternoon too. In hot regions afternoon sun is a good idea, but in any location, this is an azalea that grows in much more sun than other kinds do, so you can plant it in the open, and use it in a new garden that has not yet developed larger plants that provide shade. Planted among other shrubs around your house, or in garden beds among shrubs and flowers, this beautiful plant will quickly become a favorite in your garden.

Planting Location

Choose a spot in sun or partial shade and enrich the soil before planting with plenty of peat moss. Keep your new plants well-watered, especially during the early years. For the best growth of your azalea you should have acid soil with a pH of 6.5 or less. You can easily test your soil with a simple kit from a garden center, or if your neighbors are growing azaleas, you can too. Even if your soil is not acidic, as long as it is not strongly alkaline you can use chelated iron each spring to keep it healthy.


These plants were selected for hardiness and resistance to pests and diseases, so they will grow easily over a wide area, from cool regions with winter temperatures reaching minus 10 degrees, right into areas with hot, humid summers. Your plant needs no pruning or special care at all to bring you pleasure and a profusion of blooms for three seasons of the year.

History and Origins of the Autumn Royalty Encore Azalea

The Encore Azaleas were developed by Buddy Lee, an azalea grower in Independence, Louisiana, who crossed a rare Taiwan azalea, Rhododendron oldhamii, that flowers in summer, with other types of azaleas. After years of careful breeding, selecting and testing, he released six plants in 1995, and by adding more each year, his unique selection now includes 30 different varieties in many colors.

Autumn Royalty is undoubtedly the most vibrant of them all – a delicious rich purple that will blend beautifully with pinks, deep reds, yellows and white in your garden. These plants are carefully grown by expert growers and protected by patent, so you can be sure that unless it says Encore™ Azalea, it is not the real thing, and cheaper plants will only be a disappointment to you.
