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’

‘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’

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.

‘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.

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.
