Even though it might be a bit of a challenge, you can still grow peonies for zone 9. As long as you pick the appropriate peony variety and cultivate it properly, you can grow these plants well.

5 Varieties of Peonies for Zone 9


In this article, we’ll go over five peonies you can grow in zone 9, precisely what makes them so great, and quick tips on how to look after them.

5 Peonies For Zone 9 

1. Hibiscus

The hibiscus flower is one of those classic tropical tree peonies that makes us yearn for tropical vacations, sandy beaches, and fruity-infused drinks. Fortunately for gardening aficionados in hardiness zone 9, your climate is warm enough to sustain hibiscus plants proficiently. However, it isn’t quite the climate typical of a tropical rainforest.

There are wide varieties of hibiscus tree peonies you can grow in zone 9. Once such a variety, aptly named the Holy Grail, is a particularly unusual variety of hibiscus that can survive the coldest temperatures our climate can dish out.

Tropical Hibiscus Plant to Grow


Even though hibiscus plants may be slightly more demanding when it comes to growing peonies than some other well-known flowers, learning the foundations of hibiscus care isn’t very challenging, and their colorful blossoms are well worth the extra work. There is a lot to enjoy about these vivid, exotic flowers, which bloom continuously from spring through fall.

Water your hibiscus with warm water daily and ensure they get 8+ hours of direct sunlight daily. While the hibiscus variety does tolerate partial shade, getting them as much sunlight as possible will always give you better results.

2. Black Dragon

This dwarf variant of snake plants is called Sansevieria Black Dragon. This type can be identified by its lovely compacted rosette shape resembling the Bird’s nest plant and its dark glossy leaves. This hardy plant will survive and even thrive in zone 9, and it is incredibly simple to grow this stemless plant. It makes a wonderful interior houseplant.

The plant reaches a height of four to five feet and a width of four feet. It has an anemone shape and blooms eight inches long with a lovely scent.

Sansevieria black dragon can purify the air by taking pollutants out of enclosed areas. It creates oxygen at night, just like other snake plants, which can clear the atmosphere of any space the plant is kept in.

Black dragon fronds are thick, flat, and succulent. The leaves come in a deep, almost-black shade of green with a shiny, leather-like appearance and a smooth texture. Each blade has the form of a broad lance and is grouped in a rosette. The uneven, horizontal stripes of greenish color on the foliage are faint and hardly apparent.

The flowering of this species is quite uncommon. It can grow vertical flower stalks topped with bud clusters. The blossoms have a tint that is creamy-greenish. The tiny, tubular blossoms could have a faint scent.

This drought-resistant plant can thrive without routine watering. Throughout the season, that is optimal for growth. Typically from spring to summer, you can water it every one to two weeks.

This species is tolerant of all lighting conditions, including intense sunlight. Bright, indirect sunshine is the ideal lighting condition. Keep your house plants in a room with adequate lighting, either from natural or artificial sources.

A brief period of morning and evening sun is beneficial. However, shield the plant from the strong afternoon sun as you can end up with scorched leaves if the hot sun is too direct.


3. Alice Harding

Rich, medium-moisture, airy soils in direct bright sunlight to part shade are ideal for easy growth. During the first part of its growing season, plants require a lot of moisture. In hot summer regions, plants benefit from midday shade. When necessary, add compost before planting.

The planting peonies’ depth for the plant’s rootstock buds (eyes) should be around two inches. Every plant will bloom for about seven to ten days. P. lactiflora is a plant with a late bloom: May to early June.

By growing a mixture of the start of the season, mid-season, and late blooming cultivars, peony bloom time in your garden can be increased to around six weeks: usually late April to early June.

Alice Harding or Chinese Peony


Paeonia lactiflora often referred to as the common garden peony and sometimes as the Chinese peony, is a type of perennial herbaceous peony with an upright, clump-forming growth habit normally reaching heights of 20 to 30 inches on stems that are tinged with red.

It is categorized as a late-blooming species since it produces blooms in the middle to late spring and keeps its lovely foliage throughout the summer and the first few weeks of the fall. After a frost, stems fall to the ground. Since the 7th century, it has been cultivated in China for the beauty of its decorative blossoms.

Nine elliptic leaflets with uneven edges make up the eight to twelve-inch long, dark green compound leaves. In the fall, leaves might turn rusty or orange. Flowers with a cup or bowl form roughly three to five inches wide, with eight to ten white, pink, or scarlet petals frequently having a prominent center boss of yellow stamens.

Certain varieties bloom twice. Most varieties have aromatic flowers. Follicles that stretch out horizontally and break open at maturity make up fruits. The tuberous roots of plants are thicker.

4. Phoenix White

These plant peonies are another species you can grow in zone 9. They are best cultivated in strong sunlight to partial shade. A rich and fertile, organically fertilized, neutral to slightly alkaline, medium moisture, well-drained soil is ideal for these plants to thrive.

These plants will tolerate the heat of zone 9 summers with little to no problems. When necessary, add compost before planting. Larger shrubs require some protection from severe winds, especially when they are in bloom.

Tree peonies are woody plants, not herbaceous ones, and their stems should not be pruned after a frost since they will not wither to the ground in the winter.

Except for removing dead limbs or suckers in the early spring, there’s no need to prune this plant too often. Light pruning in the early autumn can be undertaken to shape leggy plants and promote new peonies’ growth on the bottom section of the plant.

Once the plant is done flowering, remove any spent blooms. It is better to let these long-lived plants alone once they have been planted because they typically take several years to establish. Furthermore, plant roots can grow deep, making transplantation challenging.

This tree peony is a woody, deciduous shrub with numerous stems that normally reach heights and widths of three to five feet. Large 2-pinnate leaves cover the brownish-gray stalks.

Every blade is split into 11–15 two to five-inch long oblong to oval and oblong segments. The purplish to red filaments, disc, and style of the solitary, terminal, single, delightfully fragrant white blooms (up to six inches wide) juxtapose stunningly with the yellow anthers.

Flowers of this plant blossom from April to May. The foliage is appealing all during the growing season, both on its own and when used as a backdrop or frame for other flowering plants. The flowers are very striking.

The majority of tree peonies are thought to be pest-free. Ants on peony blossoms are common and completely safe.

5. Coral Terrace

Coral terrace plants are best cultivated in full sun to partial shade, usually in deep, fertile, moist, and well-drained soil. They are tolerant of the hot summers of zone 9. Whenever you feel necessary, add some compost before planting. Larger coral terrace plants benefit from having some protection from severe gusts.

Coral Terrace is also the type of tree peonies whose stems fall to the earth in winter and should never be pruned after a frost. No pruning is necessary except for removing dead growth or suckers in the early spring. Light pruning in the early fall could be performed to shape plants that have grown too skinny and to promote new growth on the bottom section of the plant.

After flowering, remove any spent blooms. It is better to let these long-lived plants alone once they have been planted because they typically take several years to establish. Furthermore, plant roots can grow deep, making transplantation challenging.

The woody, deciduous tree Paeonia normally reaches heights of three to five feet and spreads out to a width of four feet. Large, six to eight inches wide flowers with rose pink to white petals and a purple basal band characterize the genuine cultivar.

Numerous plant cultivars have been produced, and their petal colors vary greatly, including red, pink, purple, white, and yellow. The flower forms of cultivars might be single, semi-double, or double. These plants have early spring blooms.


Due to the extremely hot summers and unprecedented changes in climate conditions, as seen in some areas of zone 9 in the last several years, it can be challenging to grow peonies in areas south of zone 9.

In this article, we’ve walked you through five striking types of peony plants you can easily grow in zone 9 with little to no effort. Equipped with this knowledge, it’s time to go out and find a new peony plant. Happy gardening!
