How To Grow Peonies In Texas - SmileySprouts (2024)

Texas is inside zones 6 through 9 of the U.S. Department of Agriculture’s plant hardiness map. Tree peony may be planted all over the state and are hardy in USDA zones 5 through 9. Garden peony will not grow in the southern lowlands or along some of the Gulf Coast, but they are hardy in USDA zones 3 through 8.

When should peony be planted?

The peony has the fattest, most delicious petals and rich green foliage, making it outrageously attractive when it is in bloom. From spring to summer, savor stunning floral displays. Learn how to care for, grow, and plant peony.

About Peonies

Peonies are a perennial that will steal your breath away every year. The plants may even outlive you—some have been reported to survive for at least a century.

When Is Peony Season? When Do Peonies Bloom?

Depending on your location and the kind you are planting, peonies bloom from late spring to early summer.

You may extend the peony season across several weeks and take use of those magnificent blossoms for as long as possible thanks to the abundance of nurseries that provide early, midseason, and late blooming types.

Peonies may thrive as far south as Zones 7 and 8, and they are hardy to Zone 3. The key to success in the majority of the United States is to provide full light and well-drained soil. Peonies even enjoy the winter’s coldness because it helps their buds grow.

Types of Peony Flowers

You can pick from six different varieties of peony flowers: anemone, single, Japanese, semi-double, double, and bomb. The odors of different plants also differ; some, like “Festiva Maxima” and “duch*esse de Nemours,” have seductive rose-like aromas, while others have a lemony scent or none at all.

Where to Plant Peonies

When planted as a low hedge or along sidewalks, peonies make excellent sentinels. As majestic and dignified as any flowering shrub, the peony’s bushy cluster of attractive glossy green leaves lasts all summer before turning purplish-red or gold in the fall.

Peonies work nicely with irises and roses in mixed borders and blossom alongside columbines, baptisias, and veronicas. Plant pink peonies with blue Nepeta or violets, then surround white peonies with yellow irises and a froth of forget-me-nots.

Peonies are not overly picky, but you should pick your place carefully because they dislike disruption and do not transplant well.

Although they can survive in partial shade, peonies like full sun, and they flower at their best in an area that receives 6 to 8 hours of sunlight per day.

Because of its huge flowers, peonies can become top-heavy in severe winds. Therefore, provide shelter. (If necessary, stakes can be used to hold them up.) Planting too close to trees or bushes will cause peony to compete with them for nutrients, sunlight, and moisture.

Grow peony in rich, wet, humus-rich soil that is deep, fertile, and well-draining. pH in the soil should be neutral.

When to Plant Peonies

As long as they are planted correctly and become established, peony plants require minimal upkeep. However, keep in mind that they do not adapt well to transplanting, so you should consider this when choosing your planting location.

Plant peony in the fall: in the majority of the United States, in late September or early October, and even later in the fall in Zones 7 and 8. Your planting zone can be found here.
If you need to move an established plant, the fall is the ideal season because the plant will be dormant.
About six weeks before the ground freezes, peonies should be planted.
While planting peonies in the spring is absolutely a possibility, the results aren’t always favorable. They often trail behind plants planted in the fall by roughly a year, according to experts.

How to Plant Peonies

Peonies are typically offered as divisions of a 3- or 4-year-old plant, bare-root tubers with 3 to 5 eyes (buds).
Peonies should be placed 3 to 4 feet apart to allow for enough air circulation. The development of disease can be facilitated by stagnant, damp air.
In a sunny area, dig a generously sized hole that is about 2 feet deep and 2 feet wide. The inclusion of organic matter in the planting hole will improve the soil. Add additional compost to the soil to improve it if it’s sandy or heavy. Add about a cup of bonemeal to the ground. Find out more about soil improvements and getting the soil ready for planting.
The roots should be positioned in the hole just 2 inches below the soil’s surface, with the root’s eyes facing upward on top of a mound of soil. Avoid planting too deeply! Choose early-blooming species, put them approximately 1 inch deep, and provide some shade in southern states.
Backfill the hole after that, being careful to prevent soil settlement and a 2-inch root burying. Gently tamp the ground.
Plant a container-grown peony no deeper than it was when it was in the pot.
When planting, give everything plenty of water.

How to Care for Peonies

Young peony take time to develop, just like children. In order to establish themselves, blossom, and flourish, they typically require a few years. They eventually leave home on their own, fully grown and adjusted… No, that’s just kids, I suppose.

Does Texas have peony blooms?

Late February to early March is when tree peony often bloom. Around April 1st, herbaceous peonies begin to bloom.

Growers have had success with all varieties of peony, including tree, herbaceous, and intersectional varieties. Itoh hybrids are another name for intersection peonies.

All plants have been harmed by the exceptional heat wave in 2012 and the drought in 2011.

One gardener claimed that many of the well-established plants in her gardens did not survive the hardship of the summers of 2011 and 2012. These include certain tree peonies, contemporary rose hybrids, and hydrangeas. Tree peonies that had flourished in the ground for 6-7 years perished as a result of drought-related stress. Despite the drought, this extremely knowledgeable gardener stated that her “Snow Lotus” tree peony has performed exceptionally well. In fact, she claimed that it is the only tree peony that she would without a doubt advise gardeners in her region to grow. She has a specimen that is almost ten years old, 4.5′ tall, and produced 26 flowers the previous year.

In Texas, amid years of drought, the rockii tree peony ‘Snow Lotus’ has proven to be a particularly dependable grower.

It makes sense that ‘Snow Lotus,’ a domesticated variation of the wild species Paeonia rockii, can withstand dryness and stress better than other varieties of tree peonies that have undergone cross-pollination under more hospitable conditions. P. rockii’s natural habitat is in northwest China, particularly in the desert Gansu Province, where there is only an average of 12 inches of rain per year. This amount of precipitation is less than half of what Dallas, Texas, received during the 2011 drought.

This image was captured in May in the countryside near Lanzhou, in the Gansu province of northwest China. The P. rockii species of tree peony is native to this area.

The rockii or Gansu Chinese tree peonies are therefore suggested for growers in hot, arid regions of the country who are interested in growing tree peony.

Herbaceous peonies are extensively grown in this region and present no unique difficulties.

Site selection: It is recommended to plant peonies in warmer regions so that they can get some shade from the intense summer sun. We advise early sun and afternoon shade for all planting zones. If this is not feasible, place peonies close to a sizable shrub so they can receive some shade from the intense sun.

At least two deep waterings per week are recommended in the spring and summer, with any additional drinks needed in between. Particularly for newly planted peonies, this is crucial.

Additional advice: At the beginning of November, remove any lingering tree peony leaves. Cut the foliage of herbaceous peonies to the ground now as well. Make sure the “eyes” or buds are essentially at the surface when planting herbaceous peonies, with only a thin coating of soil or mulch covering them.

In Texas, are peony perennials?

The huge, fragrant blooms of peonies, which are perennial plants with tuberous roots, make them highly prized. Not all locations of Texas are ideal for planting peony since they need a cool winter to thrive and bloom. If you plant them in the fall and the tubers have three or more eyes, they have a better chance of blooming the first year (buds). Check your peony tubers for rot before planting. Thankfully, you can remove rotten areas with a knife rather than discarding the plant.

Do peony thrive in the shade?

In the early 1980s, I threw a dinner party for a few friends when I first met Kasha. I gave her a tree peony blossom from my small garden at the end of the party in the hopes that it would inspire romance. It did. We started planning for our wedding and the peony garden we would create together shortly after that.

We looked for a suitable garden location for more than a year. This was nothing compared to our plant-finding expedition. We spent years writing to people and organizations in China because we specifically wanted to grow Chinese tree peonies that were not easily accessible in the United States. When we did locate someone, they insisted that we buy a large number of plants. We hurried to sell the remainder because we just wanted a handful of the top examples. However, over time, our love of tree peonies has grown into a full-time company.

Tree Peony Paeonia suffruticosa (Pay-own-ia suf-froot-i-cosa)

a slow-growing, woody shrub with huge, silky blooms that grows 4 to 10 feet tall.
USDA Hardiness Zones 3 to 9-compatible (40F to 20F).
Flowers thrive in three to four hours of light and partial shade.
Plant on a hillside or in a raised bed with lots of organic debris if you want good drainage.
Compost should be added to the soil, and in the spring, seaweed or fish emulsion should be sprayed onto the leaves.

Herbaceous peonies and tree peonies: Distinctly different plants

There are two primary varieties of peonies: herbaceous forms and tree forms. Herbaceous peonies have flowers that are 6 inches in diameter, grow to a height of 4 feet, and are simple to divide. They can produce 40 or more blossoms on a mature plant, and they do well in USDA Hardiness Zones 4 to 7 (30F to 0F). After the first cold, the majority die back to the ground after blooming in early to mid-June.

But the tree peony is a completely other kind of flower. Woody plants called tree peony can reach heights of 10 feet on their own. Their flowers are more bigger and typically bloom two weeks earlier than herbaceous peonies. They come in a wide variety of forms, colors, and perfumes. Even though they shed their leaves in the fall, they continue to have a lovely branching structure all winter long. In USDA Hardiness Zones 3 through 9, tree peonies can be grown (40F to 20F).

Tree peonies prefer dappled shade and good drainage

Tree peonies require moderate shade with three to four hours of sunlight, as opposed to herbaceous peonies, which bloom best in full sunlight. In the light, plants develop more quickly, but blooms burn and wither within a couple of days. In order to promote plant growth, we occasionally plant tree peony in full sun. However, we shade the blossoms with a parasol or fabric umbrella, which rewards us with blooms that last a week to 10 days.

Tree peony require a location with good drainage, such a hillside; standing water will destroy them. Although they don’t have any preferences, a pH range of 6.5 to 7.0 is optimal.

Unlike herbaceous peonies, tree peonies require a rest period of several weeks with temperatures between 35F and 40F before blooming. They flourish as far south as Tuscaloosa, Alabama, because of this. They can withstand temperatures as low as 30F in the winter in southern Minnesota, where they are hardy.

Tree peonies: Diversity is their hallmark

Tree peonies are divided into Itoh, or intersectional hybrids, and Chinese, Japanese, European, and American hybrids. The species Paeonia suffruticosa is commonly regarded as the parent of tree peonies. Although peony taxonomy is a complicated topic, recent research suggests that Chinese tree peonies may possibly be hybrids of two or three species. Cultivar names are the easiest to understand and recognize in the nursery industry. The names “White Light in the Night,” “Amber Moon,” “Tiger Tiger,” “Necklace with Precious Pearls,” “Princess Zhao Marries Beyond the Great Wall,” “Intoxicated Celestial Peach,” “Coiled Dragon in the Mist Grasping a Purple Pearl,” “Great Winged Butterfly,” and “Taoist Stove Filled with Pills of Immortality” are simply delightful.

Since the Sui Dynasty in the seventh century, the Chinese tree peony, or mudan, has been the nation’s favorite flowering plant. In fact, others have compared its popularity to the tulip frenzy that swept over Holland in the 17th century.

We concur that the Chinese characterize the mudan blooms as velvety. While some blossoms have a diameter of a foot, the majority are 8 to 10 inches. The Chinese cultivars of tree peony have the most range. Flowers can be white, pink, red, magenta, maroon, violet, or multicolored. They can also be any shade of these hues. Some flower petals have frosted tips, while others have darker centers. The petals’ colors frequently morph before your eyes when light hits them, relaxing in the sunlight. Flowers with light yellow petals turn lavender as they transition from light yellow to white.

In general, flower shapes can be categorized as solitary, semidouble, or double. But there is a lot of variety even within these categories. The single, light semidouble, heavy semidouble, double, ruffled ball, thousand petal, crown, and rumpled forms have all grown on our plants. Additionally, flowers might be looking up, to the side, or downward. We think that everyone belongs in the garden.

The smells of many Chinese tree peony range from sweet to peppery and occasionally even woodsy. Grand Duke Dressed in Blue and Purple, one of our favorites, with an unfathomably wonderful perfume. Let’s simply say that the aroma of heaven would be similar to that of a candy store. We plant roughly 80 of the over 600 tree peony cultivars that the Chinese acknowledge in our Connecticut garden.

The tree peony was introduced to Japan by the Chinese as a medicinal plant in the eighth century. In the 17th century, it was once more presented to Japan, but this time for its beauty. Since the plants haven’t altered in the 400 years that have passed, we believe that many of the Japanese tree peonies that are grown in Japan now are actually Chinese tree peonies.

There are, of course, exceptions. One of them is “Island Brocade,” a variation of “The Sun.” It produces gorgeous variegated pink and red flowers. The Japanese only plant single and semidouble varieties, which bloom about a week after the Chinese mudans, for their own aesthetic reasons.

Japanese cultivars of tree peony are the most widely accessible in the United States. Both local garden centers and mail-order suppliers offer them for sale.

A new species (Paeonia lutea) with tiny, yellow flowers was introduced to the West about 100 years ago. It has been crossed with semidouble types over the years in both Europe and the US. A.P. Saunders carried out this hybridization in the United States, and as a result, numerous plants bear his name today. The flowers have a beautiful citrus-vanilla scent and are smaller, frequently pointing sideways or downward. They lengthen the tree peony bloom season by blooming later than either the Chinese or Japanese tree peonies.

Nassos Daphnis and David Reath’s second generation of hybridization has resulted in flowers that are bigger and have a wider range of colors. Flowers like “Redon” and “Exotic Era,” which have yellow undertones, are highly prized.

Toichi Itoh, a Japanese hybridizer, was successful in fusing herbaceous and tree peonies about 30 years ago, expanding the range of hues available in peonies. These intersectional or Itoh hybrids are a botanical wonder; they resemble herbaceous plants in the fall yet have the leaves and petals of tree peony.

Plant peonies in the fall

All peonies should be planted and moved in the fall. Tree peony should be planted at least six weeks before the ground freezes; planting in the spring just does not give the roots enough time to grow, and as a result, they are unable to sustain the emerging leaves. As a result, peonies planted in the spring frequently become weak or die, earning them the unjustified reputation of being difficult to grow.

Make a hole that is 2 feet in diameter and deep to plant tree peony. Create a hill in the center of the hole and cover it with the roots of the tree peony. When filling the hole back up, use high-quality garden soil that is rich in organic matter, and water it well both halfway through and at the end. It’s very challenging to plant tree peony too deeply, so make sure all shoots are buried. Also, keep in mind that tree peony have a tendency to grow rather large, so leave holes around 5 feet apart. It’s a good idea to mulch your peonies the first year if plants in your environment are prone to heaving.

Tree peonies are heavy feeders

Tree peony tend to be heavy feeders because they have numerous leaves and huge blossoms. Even though we don’t fertilize them before planting, we do provide them with compost in the years that follow. Any compost that is readily available should work, with the exception of fresh manures, which require time to decompose.

Instead of piling the compost on top of the soil, we dig a 1-foot-deep by 1-foot-wide trench and fill it with the compost along the plant’s drip line. Once roots have penetrated the trench for a year or two, we repeat the procedure farther out. In the spring, we also apply a foliar spray to our tree peony, such as fish emulsion or seaweed. We use this same solution to irrigate the plants once they have bloomed.

Tree peonies are incredibly robust plants. They usually return, even if you run over them with a lawnmower. They are nearly pest- and disease-free when taken care of properly. We deadhead the flowers after they bloom, and in the fall, we remove all the leaves that have fallen. Botrytis doesn’t infect the plants in the spring because to this cleansing.

The rose borer is the only insect pest that we are aware of that feeds on tree peony. From spring until fall, it burrows into the pith of elder plants and lays its eggs. You should remove the impacted wood if you notice its telltale hole or a wilting branch.
