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.

The secret to a great garden is to always have something blooming. That’s easy in spring and early summer, but many gardens turn green after that, at least until fall arrives with its glorious leaves. Hardy hibiscus are wonderful shrubs for late blooming, that will bring any garden alive right up to the first hard frost. With its large colorful blooms Minerva Hardy Hibiscus is not just beautiful, it is easy to grow, and it thrives in sun and heat. It’s drought resistant too, and it grows even in poor soil. It’s hard to believe something this beautiful is so easy, but it’s true. These plants used to be very widely grown, but they fell out of favor for a while. Today’s gardeners are re-discovering these heirloom beauties. You should too – it will soon be the #1 favorite shrub in your garden.

Growing Minerva Hardy Hibiscus

Size and Appearance

Minerva Hardy Hibiscus is an upright deciduous shrub growing around 6 feet tall, or a little taller, depending where you live. This fast-growing bush will reach that size in only a few years, and even newly-planted bushes bloom prolifically, so you will soon be enjoying its outstanding beauty. The long stems sprout from the base, making a full and bushy plant, or you can prune it up into a tree-form. The leaves are slightly leathery and deep green, turning yellow in fall. They are about 3 inches long, with a triangular tapering base, and 3 distinct lobes at the end, edges with irregular serrations. This glossy foliage looks great in spring, even before the blooms begin.

As early as June in warm areas, but more often in late summer, the first blooms open. There are clusters of buds all along the stems, and they open one after the other, keeping this bush blooming right through fall and all the way to the first hard frost. The flowers are about 4 inches across, like wide-open trumpets, and the petals are a wonderful shade of lavender. In the center is a dark-red spot, and this spreads a soft haze of pink over the lower parts of the petals. The outside of the petals is pink. Right in the center of the bloom is a prominent column of white stamens. These exotic blooms really are gorgeous, and you will love how they keep on coming and coming. This variety has been especially bred to make no seeds. That way the energy of the plant is concentrated on blooms, and it isn’t diverted into seed production, as happens in many older varieties, which often stop flowering by early fall. This lack of seeds is the secret to the amazing abundance of blooms that never stop coming.

Using Minerva Hardy Hibiscus in Your Garden

For late blooms anywhere in your garden, Minerva Hardy Hibiscus can’t be beaten. It is ideal for the back of smaller shrub beds, or in the middle part of larger ones. Grow it as an accent at the corners of beds, or as a flowering hedge. In warmer zones it makes an excellent pot plant – perfect on a terrace or patio, and even on a balcony – yes, you don’t need a garden at all to grow this great shrub.


Hardy hibiscus is not called ‘hardy’ for nothing. Although there may be some winter damage in zone 5, Minerva Hardy Hibiscus will bounce back in spring, and since it blooms on new stems flowering won’t be affected at all. It loves heat, so you can grow it in the hottest zones, and it thrives in humidity too.

Sun Exposure and Soil Conditions

Plant your Minerva Hardy Hibiscus in full sun for the best blooming, but it will tolerate a few hours of shade each day if it has to. It thrives in any well-drained soil, both acid and alkaline, and in clay too. Richer soils give the best growth, but drainage is important, and once established it is drought resistant.

Maintenance and Pruning

Water new plants regularly, and in summer established plants benefit from a deep soaking every couple of weeks. In sandy soils some mulch over the roots is beneficial too. Pests and diseases don’t normally bother Minerva Hardy Hibiscus, and deer usually leave it alone. We suggest an annual pruning in spring, for the best results. If you want the largest possible flowers, on a smaller bush, such as in a pot, you can prune back the stems from the previous year to just 2 or 3 buds. For larger garden plants leave about 12 inches of the previous year’s growth. Remove some of the oldest stems at the base at the same time, to open space for new flowering shoots to develop.

History and Origin of Minerva Hardy Hibiscus

The hardy hibiscus, Hibiscus syriacus, has been grown in gardens for longer than most other plants. It was first grown in Europe in the 16th century, arriving from Syria, where in turn it had arrived along the ancient Silk Route from China, its homeland. With our hotter summers and drier fall, it grows better here than in Europe, and it was more popular in the 19th century than roses. You will also find it grown with the names Rose of Sharon, and also as Althea. We thank the famous plant breeder Dr Donald Egolf for the variety called ‘Minerva’. He worked for many years at the Floral and Nursery Plants Research Unit of the US National Arboretum, D.C. In the 1970s he crossed together several different older varieties and used breeding techniques that create plants that won’t make seeds. This means they keep on blooming and blooming. He selected his most beautiful seedlings, and ‘Minerva’ was released in 1986.
