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 Fireworks Double Hardy Hibiscus brings you an amazing display of multiple colors on a single bush. Growing 6 to 8 feet tall, some blooms will be pink, others purple-red, and others mauve. Blooming begins in summer and continues to the first hard frost. The glossy foliage is rich green, and this vigorous, upright, deciduous shrub is a winner for tubs and for any sunny spot in your garden, even those hot and dry ones.

  • Delightful double blooms of white, pink and red
  • Long blooming, in flower from summer through fall
  • Thrives in sun and heat
  • Perfect for a tub or planter on your terrace
  • Desirable heirloom varieties

A sunny position is best for the Fireworks Double Hardy Hibiscus, but it will take a little partial shade too, especially in hot zones. It will grow in any well-drained soil, including sands and clays, and in tough urban conditions. Occasional deep watering in summer will keep it growing well, but it is drought resistant too, once established. Pests and diseases don’t normally bother it, and deer usually leave it alone.

Growing the Fireworks Double Hardy Hibiscus

Size and Appearance

The Fireworks Double Hardy Hibiscus is a vigorous deciduous shrub with a vase-shaped or rounded habit, with branching to the ground. It will grow to 8 feet tall in warm zones, when planted in a sunny bed, and stay more compact in a planter. The leaves are around 3 inches long, with a narrow base flaring out into 3 rounded lobes, with jagged edges. They are a rich, glossy, dark green, which holds well through the summer, before finally turning yellow in late fall.

The first flowers should appear by June in warm zones, and by July in cooler ones. Clusters of buds form on all the new shoots, and on short side-shoots that develop in a couple of years on older stems. The flowers last just a few days, but they are replaced by more and more, with flowering continuing right up the first hard frost. The flowers are all double forms, that is, they are not the open funnel of some hardy hibiscus, but a bowl of large petals filled with many smaller, thinner, often twisted petals, creating a brilliant pom-pom up to 5 inches across. The flowers may be gorgeous pink, rich purple-red, or a wonderful purple-mauve with blue overtones – all three colors appear on the same bush, on different branches. At the base of the petals you will see a blood-red pool of color develop as the flower opens fully, highlighting the brilliant main color of the bloom.

Using the Fireworks Double Hardy Hibiscus in Your Garden

This colorful shrub is perfect for growing in pots and planters, where it will bring a spectrum of coordinated colors to a patio, or even on a balcony, for those who have no garden at all. Plant it by a doorway or gate, for a bright explosion of color to greet you and your visitors. Grow it in beds, surrounded by other pink, purple and red flowering shrubs for a vibrant display. Plant in a row for a tapestry hedge or screen that has to be seen to be believed, it’s so vibrant and colorful.


You can grow the Fireworks Double Hardy Hibiscus anywhere from zone 5 to zone 9. In zone 5 there may be some winter damage, but it will quickly re-sprout in spring, and since blooming takes place on new stems, it will still flower profusely, although on a shorter bush.

Sun Exposure and Soil Conditions

Although some partial shade is fine, full sun is best for the Fireworks Hardy Hibiscus, particularly outside the hottest zones. It will grow in any well-drained soil, including poor and dry soils, but for maximum growth and blooming, richer soils are preferred. Once established it has good drought resistance.

Maintenance and Pruning

A deep soaking from time to time through summer will keep your bush in top condition. In planters, use liquid fertilizer for flowering shrubs regularly and use a granular shrub fertilizer in spring for plants in beds. Some trimming back of last-year’s stems in spring will keep it compact and vigorous. Note that this tree cannot be trained into a single stem, as there are three roots in the pot. When pruning be careful not to remove any stems at ground level – you should be able to identify the three plants by looking at the growth as it leaves the soil. Harder pruning back to 2 or 3 buds on last-year’s stems will encourage larger flowers on a smaller bush.

History and Origin of the Fireworks Double Hardy Hibiscus

The hardy hibiscus, Hibiscus syriacus, is a plant that has been grown in gardens for many centuries. It grows wild in parts of China and India, and it has also been grown in gardens there, and in Korea, for as long as there are records. It travelled west along the Silk Route, and it was in England before 1600. It was equally popular in America and grown by Thomas Jefferson. It enjoyed enormous popularity in the 19th century, and many of the varieties we grow today we created back then.

The variety called Fireworks Double is a tribute to those early breeders, and also to the skills of the modern grower. Our growers take three different plants and raise them together in a single pot to create a balanced, multi-stemmed plant. The pink blooms are the variety ‘Lady Stanley’, an English creation from 1875. Its beauty is enhanced by the deep red color at the base of the glowing pink petals. The red flowers are ‘Amplissimus’, a very old plant probably from France, that certainly existed by 1861. The rich purple-red coloring is enriched by the elegant twisting of the central petals. Linking these colors is ‘Ardens’, a variety with wonderful mauve to light purple-blue blossoms, again with a hidden heart of deep red. Little is known of its exact origins, but it is probably also French, and certainly known by 1873.
