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 Limelight Prime® Hydrangea is a fabulous replacement for the older Limelight panicle hydrangea variety, with a more compact size for smaller gardens. The stems are stronger, the blooms just as beautiful, with a new twist – they turn pink and red in late summer and fall. The beautiful conical bloom heads are produced in profusion, starting chartreuse-green in bud and opening to a beautiful green-white. Fast-growing and soon reaching 4 to 6 feet tall, this compact bush is perfect in your shrub beds, among evergreens, planted above flowers, or in a row along a fence or wall.

  • More compact version of the classic ‘Limelight’
  • Strong stems carry large panicles
  • Lime green buds open to white-green flowers
  • Blooms last weeks, turning pink and red in late summer
  • Tough, reliable and easy to grow

The Limelight Prime® Hydrangea is very adaptable, growing in all zones, and thriving in full sun or partial shade. Good drainage is important, but otherwise it will grow in almost any kind of soil, and needs less water than mophead hydrangeas. It is generally free of pests or diseases, and only needs a spring pruning to give you results you will be super-proud of. Step into the spotlight of great gardening with ease, and plant this wonderful shrub.

When the Limelight Hydrangea stepped onto the stage early this century, it stepped into the spotlight, ready to take over from the tired old P.G. hydrangea, and bring fashionable chartreuse green into the garden palette in a big way. It quickly became one of the most popular shrubs ever, but 20 years later it’s time for it to move to re-runs, and step out of its prime-time slot. Now we have its new-generation replacement, because even the best can be improved. Welcome into your garden the Limelight Prime® Hydrangea, a shrub that gets as close to perfect as any plant can be. First of all it blooms earlier, which is great news for those of you in colder zones, who have had to wait till August. Plus, it has stronger stems, able to bounce back after summer storms, and stand proud for month after month. It’s just as cold-hardy, but more compact – perfect as our gardens get smaller too. Finally, instead of fading to sandy brown, it takes on splendid shades of pink and red as the blooms age, stepping into fall for a great finale. Wow, talk about a dead-cert for a Golden Globe.

Growing the Limelight Prime® Hydrangea

Size and Appearance

The Limelight Prime® Hydrangea is an upright deciduous shrub that grows rapidly to become 4 to 6 feet tall and wide. It has many thick, strong stems that shoot from low-down, but it can also be easily trained to have one or a few main stems with a higher crown. The bark is light brown, slightly peeling, becoming rougher and more corky with age. This plant is a type of panicle hydrangea, so the leaves are smaller, thinner and lighter green than we see in the mophead hydrangea. They are about 2½ inches long, broad ovals tapering to a point, with boldly serrated edges. They are mid-green, turning clear yellow in fall, with a textured surface and pronounced veins.

Flowers develop at the ends of every new stem, held up well by extra-strong stems. They first show around mid-summer, but this can be earlier or later depending on the climate zone they are in. Flowers are carried in large, conical heads with around 200 flowers per head. These heads are fat, tapering cones, 3 to 4 inches long, but variable in size, depending on pruning techniques. The individual flowers are about 1-inch across, with 4 flat petals, colored in bud and when freshly opened a bright, light chartreuse or lime green, maturing to white-green, and then turning pink and red, particularly when colder temperatures arrive in early fall. The flower heads last for many weeks, and new ones develop on new stems, so this shrub is in bloom from mid-summer to mid-fall, still looking attractive even after the flowers have died.

Using the Limelight Prime® Hydrangea in Your Garden

The wonderful chartreuse tones of the Limelight Prime® Hydrangea fit perfectly into every garden, of any style, and the long bloom period means more bang for your buck in a small space. Plant it at the back of smaller beds, or the middle-zone of larger ones. Grow it among the evergreens around your home, for summer and fall interest. Plant it in a row, spacing plants 3 to 4 feet apart, along a fence or wall, for a great look, or grow it in more natural parts of the garden. From zone 6 on it also makes a great container plant, with lots of interest.

Hardiness

Unlike mophead hydrangeas, panicle hydrangeas like this one grow well even in cold zones, and it thrives in zones 4 and 5. It will also grow in warmer parts of zone 3. The Limelight Prime® Hydrangea grows just about everywhere, to zone 8 in the southeast, and in zone 9 in the northwest. It needs no special winter protection, and because it flowers on new stems any winter damage is of little consequence, and plants still bloom well.

Sun Exposure and Soil Conditions

Very adaptable to light, the Limelight Prime® Hydrangea will bloom best, and have the strongest stems, when grown in full sun, although in hotter parts of the country some afternoon shade is beneficial in summer. It is much more sun-tolerant than a typical mophead hydrangea. It will grow rapidly in almost any well-drained soil, but grows best in richer soils, so add organic materials when planting. While it has some drought tolerance, a regular water supply is best, but don’t over-water. This plant needs good drainage, and too much water, especially in winter, or if your soil is clay, is harmful. Loose, open soils give the best results.

Maintenance and Pruning

Usually free of pests or diseases, and both fast-growing and easy to grow, the Limelight Prime® Hydrangea is a trouble-free shrub for all gardens. For the best results, prune is spring, following the guidelines you will find in this blog. Some fertilizer for flowering shrubs, applied after pruning, is also beneficial, and in warmer zones some mulch over the roots is valuable.

History and Origin of the Limelight Prime® Hydrangea

The panicle hydrangea, Hydrangea paniculata, grows in China and Japan, where it can be as much as 20 feet tall in the wild. The original garden plant we know as the PG Hydrangea, (Hydrangea paniculata ‘Grandiflora’), came from Japanese nurseries in the 1870s. for many years it was all we had, but in the last few decades breeders have given us a whole range of these valuable plants. The variety called ‘SMNHPPH’ was created by Timothy Woods of Spring Meadow Nursery in Grand Haven , Michigan. In the fall of 2012 he collected seed from an earlier variety he had created called Pillow Talk® (`SMHPZIND`), a compact bush with white flowers that turned pink. Among his many seedlings he found one with super-strong stems, compact growth and beautiful lime-green flowers. It was patented in 2020 and released by Spring Meadows with the trademark name of Limelight Prime®, under their Proven Winners® brand.
