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.

We all love raspberries, almost as much for their amazing color as for their taste. It’s a great garden color too, standing out and catching the eye right across the garden. You can enjoy that color, and see blooms right up to frost, by growing the Raspberry Smoothie™ Hardy Hibiscus. This brilliant new variety has all the toughness you need, plus a long blooming season, and its bright purple-red flowers make a stunning contrast in the garden, especially in fall, with all those yellow leaves around. A bush in full bloom surrounded by the golden glow of fall is a wonderful sight indeed. Just like all hardy hibiscus – you might call them Rose of Sharon or Althea – it thrives in sun and heat, and makes a neat, compact bush. The flower is a unique double bloom with broad outer petals like a shallow bowl. You will love it in the garden or in a planter on your patio.
Growing the Raspberry Smoothie™ Hardy Hibiscus
Size and Appearance
The Raspberry Smoothie Hardy Hibiscus is a deciduous shrub with strong upright growth, quickly growing into a medium-sized shrub 6 to 8 feet tall and 3 or 4 feet wide. It has many stems from the base, although it can be pruned up into a tree-form as well. It branches naturally to develop a dense structure. The leaves are about 3½ inches long, and 2½ inches wide, with a slightly leathery texture and a smooth, glossy surface. They flare out from the base into three distinct lobes, edged with jagged, irregular serrations. They are rich green, and that color is held well, even though hot and dry weather. They turn bright yellow in late fall.
Blooming begins early compared to many other varieties. It can be in June, or into July. Once it begins, blooming continues non-stop through summer and fall, often only coming to an end when hit by a hard frost. The flowers are sterile, which means this plant produces no seeds, so it doesn’t waste energy on seed-pods. Instead it just keeps making more and more blossoms. This keeps it blooming much longer than older varieties you might have grown before. The bloom is simply amazing. It is 4 to 5 inches across with a shallow bowl of broad petals forming a backing for a swirling center of slender, twisted petals that create the heart of the bloom. It looks nothing like the old trumpet flowers of hardy hibiscus, and it is different from many of the pom-pom doubles too. The color is also amazing – a rich, bright, clean purple-red, with many variations in shade across the petals, with light and dark shades bringing enormous depth and beauty to the flower. Flowers last 2 or 3 days and then drop, without any deadheading being needed.
Using the Raspberry Smoothie™ Hardy Hibiscus in Your Garden
With its vibrant coloring you will love to grow this bush as a striking lawn specimen. Grow it behind smaller shrubs, or in the middle of your beds in front of spring-flowering trees – it’s very useful for getting a succession of blooms from your garden beds. With its striking flowers it is also perfect beside a door or gate, or excellent growing in a tub or planter on a terrace or patio. Heck, you can even grow it on a balcony, with no garden at all.
This plant thrives in warmer zones, and it is hardy all the way into zone 5. There it may have some branches killed in winter, but don’t worry about that. It soon sends up vigorous new shoots, and they bloom profusely, as this plant always blooms on new shoots. In warmer zones it will grow very well, including places with hot summers.
Sun Exposure and Soil Conditions
Grow the Raspberry Smoothie Hardy Hibiscus in full sun for the best results and the most prolific flowering. If it does have a few hours of shade in the afternoon this usually has little effect. Avoid too much shade. This tough shrub grows well in almost all soils, as long as they are well-drained. Avoid wet, low-lying areas, especially in cooler zones. It grows in hot areas, and once established it has good drought resistance.
Maintenance and Pruning
Established plants should have a deep soaking from time to time during the heat of summer. If the leaves turn yellow in summer it is often an indication of too much water, so cut back a little. Pests or diseases are rare, and deer usually leave it alone. In early spring a trimming will give good results. Shorten back last year’s stems to about 12 inches and remove about one-third of the oldest branches, opening the center to encourage new young branches. In pots trimming back to just 2 or 3 buds will encourage the largest flowers and keep your bush smaller for a smaller space. Don’t trim new stems at all in summer, as this will inhibit flowering.
History and Origin of the Raspberry Smoothie™ Hardy Hibiscus
Hibiscus syriacus, or the hardy hibiscus, is a relative of tropical hibiscus and of cotton and okra. It has been grown in gardens for centuries but grew wild in China and India. Plants traveled along the Silk Route to Syria, and from there it came to Europe before 1600. It was very popular in America in the 18th and 19th centuries but fell from interest last century. Today it has been revived, and wonderful new varieties keep arriving to charm and fascinate us.
Don Shadow has a nursery in Winchester, Tennessee, and he is a skilled breeder of hardy hibiscus. In the early part of this century he created a series of double-flowered varieties making up the Smoothie collection. The variety he called ‘DS03RS’ was found among seedlings he grew from some other varieties he had created. He selected it in 2007, and after trials he patented it in 2016. It has been released for our enjoyment with the name Raspberry Smoothie™, by the Greenleaf Nursery Company of Park Hill, Oklahoma.
