Purple is the color of extravagance and nobility. In ancient textiles, the shade was reserved for only the wealthiest of customers, as it was difficult and very costly to obtain the dye. It is also the very favorite color of bees. From honeybees to bumblebees and everything in between, bees see purple very well, so they tend to be most attracted to flowers in this color family.
In the world of hibiscuses, purple is one of the least common colors and is typically grouped together with blue, as these are even rarer, and the colors often appear together in the same flower.
Interestingly enough, the color can appear in both cold hardy and tropical species. While cold hardy plants lean more in the blue direction, tropical varieties tend to fall on the rosier side of the color wheel. From eggplant to lavender and every shade in between, here are some of my favorite purple hibiscus varieties!
‘Amethyst’
botanical name Hibiscus cannabinus ‘Amethyst’ | |
sun requirements Full Sun to Part Shade | |
height 3’-4’ | |
hardiness zones 5-9 |
‘Amethyst’ is a wonderful cultivar of the cannabinus species. This deciduous plant is a compact variety with narrow, serrated, deep green leaves. The foliage is unique and delicate, making this a standout in the garden. Growing to a petite height of just 3’-4’ tall, this is a hibiscus that will fit in small spaces and makes a great container plant as well.
The flowers on ‘Amethyst’ are simply lovely. They are pure white with a deep purple heart radiating outward from the center of the blooms. A purple column supports lots of golden pollen and draws plenty of pollinators. The petals have a corrugated texture, adding another level of interest to the blooms.
‘Ardens’
botanical name Hibiscus syriacus ‘Ardens’ | |
sun requirements Full Sun | |
height 8’-10’ | |
hardiness zones 5-8 |
This pretty and stately variety of H. syriacus grows fairly tall and upright in a wonderful vase shape. This makes it wonderfully planted in groups as a screen or hedge. Its maple-like foliage is an attractive bright green shade, forming a perfect backdrop for its stunning blooms.
The large flowers of this cultivar are double-petaled with a peony-like appearance. Fluffy confections of orchid purple cover the plant from early summer until the first frost. The flowers only bloom for one day each, but this plant is such a prolific producer the blooms will be nearly continuous throughout the season.
‘Bayou Rose’
botanical name Hibiscus rosa-sinensis ‘Bayou Rose’ | |
sun requirements Full Sun | |
height 2’-4’ | |
hardiness zones 9-11 |
‘Bayou Rose’ is a chameleon in the hibiscus world. A tropical species, this plant can only be grown in the ground in zones 9-11. It will not tolerate freezing weather. The good news is that it has a maximum height of around 4’ tall, which makes it the perfect size for a large pot.
What makes this hibiscus special are its hypercolor flowers. The fully double blooms open for two days. On the first day, upon opening, they have a soft lavender interior with bright pink edges to their many ruffled petals. By the second day, the petals will turn completely lavender and slightly expose the pink stigma and yellow pollen center.
‘Blue Bird’
botanical name Hibiscus syriacus ‘Blue Bird’ | |
sun requirements Full Sun to Part Shade | |
height 6’-8’ | |
hardiness zones 4-9 |
This fast-growing variety can reach up to 12’ tall in one season and has a rounded vase shape. The leaves are deep green with a maple-like appearance. ‘Blue Bird’ performs well in full or partial sun and likes its soil to remain moist but not soggy.
Blue Bird’s blooms are a knockout. Only the edges are a deep periwinkle blue, while the interior of the flower is an ombre in different shades of purple with a deep burgundy in the center. The blue at the edges makes these a unique and standout flower in the garden.
‘Blue Satin’
botanical name Hibiscus syriacus ‘Marina’ | |
sun requirements Full Sun to Part Shade | |
height 6’-9’ | |
hardiness zones 5-8 |
‘Blue Satin’ goes by a handful of different names, including Marina and Althea. This upright shrub finds its way to about 9’ tall by the beginning of fall. It is tolerant of full sun or partial shade and has large, tri-lobed leaves in bright, cheerful green.
The flowers are sterile, so they do not drop seeds, which is both a blessing and a curse, since they are so lovely. The flowers are blue-violent with a single-petal form and a deep eggplant purple eye. The stigma and pollen are white, lending an ethereal quality. Flowers bloom for only one day, but the plant blooms heavily late in the summer.
‘Blueberry Smoothie’
botanical name Hibiscus syriacus ‘DS01BS’ (PP#26,662) | |
sun requirements Full Sun to Part Sun | |
height 6’-8’ | |

The name is a funny one, but when you see these flowers, it will make perfect sense. Like its namesake beverage, the blooms on ‘Blueberry Smoothie’ look like they were swirled around in all directions. This variety probably has the most densely petaled flowers of any cultivar I know of. They look like large peonies with varying shades of purple throughout each individual bloom.
This nice-sized deciduous hibiscus makes a gorgeous container plant and is an easy plant to grow. Its leaves are large with three lobes and glossy in medium green. ‘Blueberry Smoothie’ has an upright habit but forms many branches and has a wonderfully dense structure.
‘French Cabaret Purple’

The French Cabaret series is strongly upright and showy. This hibiscus will make its mark in the garden with its towering branches and bright green maple-like leaves. Hardy to zone 8, this variety is somewhat less heat tolerant than many on this list. But if you’re able to grow it in your zone, you won’t regret it.
This shrub has large light purple flowers with many fluffy, ruffled petals. Interspersed with purple, the flowers have bits of white, typically toward the center of the blooms. They bloom for about 8 weeks in midsummer.
‘Lavender Chiffon’

Minerva’s flowers are simply wonderful. The color is a glowing lavender with just a hint of pink to the interior of the petals. They have a deep red eye, creamy white stigma, and pollen in the center. These pretty flowers have a light and airy appearance and bloom in midsummer.

A very large, splashy, deep red eye looks like a starburst in the center of these semi-double-petaled blooms. The outer petals are a lovely lavender shade, veined with the deep wine red of the center. The flowers are mid-sized and very eye-catching. The semi-double form adds a sweet softness to the form of the blooms as well.
