Finding the right color of flowers for your garden can be difficult. I am particular to roses myself, but when it comes to purple and blue blooms, I have to turn to other options. Some of the prettiest shades of lavender I have ever found have come from the Phlox divaricata, commonly called the woodland phlox.

Ranging from lavender to blue, the Phlox divaricata is a small, native wildflower with dainty flowers that bloom in  April and May. It grows to be 8 to 12 inches high and equally as wide. It does well in partial shade to full shade gardens.

As an added bonus to its lush color, the woodland phlox is known to attract hummingbirds and butterflies. If left to grow in your garden, the woodland phlox will form large colonies over time, as wildflowers tend to do.

The Duke Gardens Fall Plant sale will feature the 'Blue Moon' Phlox divaricata, known for its deep violet-blue flowers. Its blooms are not only colorful but very fragrant. The 'Blue Moon' is a good complement for gardens with ferns and hellebores and is certain to please gardeners seeking to bring a variety of color into their gardens.

Fall Plant Sale Preview: Celebrating Pollinators

 By Jason Holmes

While visiting Mount Mitchell State Park in western North Carolina over Labor Day weekend in 2016, I witnessed a native bee pressing open the lipped petals of the pink turtlehead (Chelone lyonii).  It made me think of the importance of that moment and yet how that bee had already visited hundreds of flowers that day in order to collect pollen on the side of her legs. I quickly yelled to my son to come get an up-close view. This was a perfect opportunity to show him the importance of that little creature.

Insect pollinators may seem like a small part of our daily lives, but they have an enormous impact on us. Fortunately, gardeners’ interest in pollinators appears to be growing, judging from sales of pollinator plants at our Fall & Spring Plant Sales. That's heartening for horticulturists like me, who are devoted to attracting pollinators to Duke Gardens and teaching visitors about these species’ roles in our lives.

Most people don’t realize that honeybees are not native to North America and that thousands of other insect species were responsible for pollinating many plant species before their introduction. Bees and wasps, flies, butterflies and moths, and beetles are among the thousands of plant pollinators across North America. These beneficial insects are responsible for all insect-pollinated fruits and vegetables that provide us with most of the nutritious vitamins and minerals that we need daily, and they also broaden our diets beyond just meat and wind-pollinated grain foods.

This act of pollination allows many types of plants to produce fruits and seeds, helping to create vigorous plants over many generations.

Approximately 75 percent of all plants in the world require animals for pollination. These animals are part of many humans’ daily diets, something worth keeping in mind as we seek ways to help the plants around us thrive.

At Duke Gardens, we celebrate and promote all types of pollinators.  In the Charlotte Brody Discovery Garden, a sustainable organic food garden, we donate over a ton of fruits and vegetables every year to local food relief organizations.  This is an amazing total, considering that we only garden on 2/10 of an acre.  We could never produce this incredible amount without assistance from the thousands of pollinators we see daily buzzing around the garden. In the Brody Garden, and in the Blomquist Garden of Native Plants, we have gardens designed specifically to attract these fascinating little pollinators.  We have nine honeybee hives in the Brody Garden. And with the help of dedicated volunteers, we have been building pollinator houses that we’re pleased to see attract many different beneficial species.

If you’re excited about helping pollinators, try planting species that will bring them to your garden. “Attracting Native Pollinators,” by The Xerces Society, is a great resource to learn more. If you already have these plants, consider leaving perennials longer through the fall and winter for habitat. Many of these species will create nests within the dead stems of perennial species.  Get creative and build pollinator houses or insect hotels. They’re similar to bird houses, but you leave off the front wall and pack it with small stems of bamboo so that solitary insect species can build nests inside.  Remember, if you build it, they will come!

"The Big Easy" lives on


We were all sad to say a sudden farewell to "The Big Easy," Patrick Dougherty's beloved sculpture on the South Lawn. Alas, storms and flooding in spring and summer took too great a toll on this intriguing art installation, and it became unstable.

But we have some good news! Most of the finials held their shape beautifully when removed from the main sculpture, so—with  Dougherty's blessing—our curators and horticulturists found perfect locations throughout Duke Gardens for the finials to enhance the landscape design and stay with us  awhile longer.

We hope visitors will enjoy encountering these small echoes of a big attraction. If you take photos of them and post online, please tag #dukebigeasy. We'd love to see them!

The dismantling begins. Photo by Clarence Burke.

And here are the finials....can you guess where?

Japanese Maples at the Terrace Shop

Acer palmatum 'Peaches and Cream'
By Annie Yang
Duke Class of 2020
Photos by Annie Yang

If you missed this month’s Spring Plant Sale (our most successful ever -- thank you!) or if your garden is calling out for more, there are still plants available in Duke Gardens' Terrace Shop, including many cultivars of Japanese maples (Acer palmatum).

Native to Japan, China, Korea, eastern Mongolia, and southeast Russia, these plants are super versatile and come in all sorts of shapes, sizes and colors. Some varieties are naturally smaller and shorter and can grow in containers. Other cultivars can serve as understory plants grouped together in shady woodland areas of a garden.

Japanese maples usually run relatively small for trees, but some of them can stand out even when planted alone. Their leaves run a whole spectrum of colors: red, orange, yellow, green, purple. In general, they prefer some afternoon shade but also a good deal of sunlight to showcase their colorful foliage.

Japanese maples require well-drained and consistently moist soil, as well as protection from strong winds. Watch out for late spring frosts, which they are especially vulnerable to when young. Despite this, many cultivars are relatively easy to grow and are long-lived. Below are a few of the Japanese maple cultivars available at the Terrace Shop. We recommend that you call in advance (919-684-9037) if there is a particular cultivar you are seeking.
Acer palmatum 'Summer Gold'


‘Summer Gold’

True to its name, ‘Summer Gold’ maintains an energetic yellow color throughout the summer, as well as the fall. Its foliage starts off light green in the summer and deepens into the fall, retaining wonderful shades for months.

Standing at 10 to 12 feet at maturity, ‘Summer Gold’ is a somewhat taller tree compared to its Japanese maple relatives. This tree thrives in well-drained soil and has average water needs. It is also resistant to deer and insects, and it is drought tolerant. ‘Summer Gold’ distinguishes itself from other Japanese maples not only with its color but also with its ability to withstand full sun without burning. This is a tree that is well adapted to the summer and isn’t afraid of full sun, heat or humidity.

‘Autumn Fire’

The leaves on this deciduous tree start off typically green like any other tree you might encounter in the early spring. But as spring transitions into summer and then into fall, ‘Autumn Fire’ begins to show its true colors. The edges of its unique, narrow leaves are first tinged with red, and eventually a fiery red engulfs the entire leaf. In the fall, ‘Autumn Fire’ is alight with its stunning scarlet hues, standing out even in a season packed with attractive foliage colors.
Acer palmatum 'Autumn Fire'

‘Autumn Fire’ grows to be about 6 to 8 feet tall and requires well-drained, rich soil and regular watering. As a bonus, ‘Autumn Fire’ can also tolerate humidity. Like many Japanese maples, this tree prefers full to partial sun. But be careful exposing ‘Autumn Fire’ to too much full sun or else it will really burn!

‘Peaches and Cream’

When I first encountered this tree, I wasn’t sure what was so “creamy” about ‘Peaches and Cream’. There seemed to be a lot more peaches implied by the red than any cream or white! But to truly appreciate ‘Peaches and Cream’ you really have to follow it through the seasons. In the early spring, the leaves on this deciduous tree actually take on a pale green, almost white color, accentuating its veins, which are still dark green. As the weather gets colder, the cream is replaced by an orange-yellow color reminiscent of sweet summer peaches.

As with other Japanese Maples, ‘Peaches and Cream’ is on the shorter side, from 6 to 12 feet tall, but it certainly makes up in personality and vibrancy what it lacks in stature. ‘Peaches and Cream’ thrives in acidic, well-drained and rich soil, and it is also drought and humidity resistant. This tree can grow under mostly sun to mostly shade, but it prefers the shade. Imagine enjoying a bowl of peaches and cream under the cool canopy of a tree during the summer!

The following cultivars may also still be available through the Terrace Shop: Vitifolium, Taki no Gawa, Green Mist, Skeeter’s Broom, Crimson Princess, Katsura, Alan’s Gold, Calico, Meigetsu, Little Cindy, Emerald Lace and Tamukeyama.

Thank you again to all shoppers for making the 2018 Spring Plant Sale our most successful ever! If you love gardening, remember that Duke Gardens members get 10% off all plant purchases at the spring and fall sales, and first dibs at the members-only preview sale in spring.

Spring Plant Sale Preview: Sedum + Sempervivum

Sedum 'Lemon Ball'
By Annie Yang
Duke Class of 2020

The bright yellow-green foliage of Sedum ‘Lemon Ball’ bursts out like fireworks and radiates excitement and freshness. It’s one of six Sedum varieties we will have at our Spring Plant Sale on Saturday and members-only preview sale this evening (see event details below). ‘Lemon Ball’ is a close cousin of ‘Angelina’, another Sedum variety, but it retains its vibrant color all year.

‘Lemon Ball’ requires full sun (you wouldn’t want to hide this plant in the shade!), and it grows in dry soil with average watering. It is also sturdier than ‘Angelina’ and is drought tolerant as well as rabbit and deer resistant. Fittingly, ‘Lemon Ball’ blooms in the summer and fits right in with the other bright, exciting colors of the season.

This plant works well as a border plant, lighting up any walkway or garden path. ‘Lemon Ball’ can also pop out in rock gardens without distracting from the beauty of the stones. You can even bring them indoors and place them in a hanging planter. ‘Lemon Ball’ will certainly stand out in any niche you find for it.

Scroll down to see more Sedum from our plant sale collection, as well as the popular Sempervivum 'Carmen' (hens and chicks).

Spring Plant Sale Preview: Bee Balm

Bee balm (Monarda).

For those who love bees, butterflies and hummingbirds, consider the Monarda plant, commonly known as bee balm, which we’ll have in nine varieties at Saturday’s Spring Plant Sale and tomorrow’s members-only preview sale (event details below).

 Of those nine, three are from the Sugar Buzz series. Released in 2014 by Walters Gardens Inc., this family of Monarda is extremely resistant to powdery mildew, a fungus that previously prevented many gardeners from introducing Monarda into their collections.

Each variety of Sugar Buzz Monarda features dark green foliage that smells of mint—thus its attractiveness to pollinators such as butterflies. Monarda is a hardy plant and can survive in full sun or partial shade with consistent, regular watering, and Sugar Buzz varieties are deer and rabbit resistant.

When cared for properly, Monarda will spread quickly. It’s often planted in perennial borders, but it is also a favorite for container planting, as the sturdy foliage allows flower clumps to form upright and prevent drooping.

The Sugar Buzz varieties of Monarda are favorites for summer-blooming gardens, and all varieties bloom around the same time, making them perfect choices to plant together.

In our Sugar Buzz trio this weekend, ‘Bubblegum Blast’ will give you the bright pink splash that its name implies. It is perfect for perennial borders and mass planting. It’s also easy to grow, heat and humidity loving, and will clump and spread with average care. ‘Cotton Candy’ features pale pinky purple flowers with lighter centers and lavender dots. Monarda “Grape Gumball” is the darker variety of the bunch, displaying deep magenta blooms.
Monarda

Our Monarda selections will also include Monarda didyma ‘Purple Rooster’, which provides the perfect purple complement to the Sugar Buzz series. This plant features true purple flowers and clean foliage. Its stalks are so sturdy that even the blooms reaching 3 feet tall do not require stakes.

Monarda didyma ‘Purple Rooster’ blooms in mid to late summer with fragrant foliage and flowers. The plant grows most quickly in full sun, but spreading will occur more rapidly in partial shade. In addition to attracting pollinators, it is deer resistant. To encourage flowering, foliage should be cut back at the end of every re-bloom.

Plant Sale Preview: Heuchera

Duke Class of 2020

Heuchera, commonly known as coral bells, has grown increasingly popular with gardeners for its adaptability and because butterflies love it. We will have five varieties at our Spring Plant Sale this  Saturday (event details below), and Duke Gardens members can get first dibs at Friday’s members-only preview sale. Here are two varieties that gardeners are sure to love.

Heuchera ‘Rose Quartz’ is a gorgeous metallic-looking plant best known for the holographic effect of its impressive foliage. The leaf color starts out as a light dusty rose before transitioning to a light pewter color. In early summer, pink buds give way to cream flowers, making this the perfect summer-blooming perennial to add to any garden.

Heuchera ‘Rose Quartz’ attracts butterflies, hummingbirds and bees, and it’s deer resistant. This is a fairly easy-to-grow plant that demonstrates more tolerance of heat and humidity than many other species. Native to the Southeast, Heuchera ‘Rose Quartz’ thrives and produces the most vibrant colors in partial shade environments, although it will also do fine in full sun with constant moisture. In the spring, any damaged leaves should be removed for optimal regrowth. Good drainage is crucial to this plant, and when it is given consistent care, it may act as an evergreen.

The colorful spread of the ‘Rose Quartz’ foliage can reach 12 inches, making it a focal point for borders and containers. Planting time is from late winter to late spring or late summer to early fall. Late summer will provide the best display of blooms in the spring. Consider using this plant to provide a mysterious shimmer to your garden border.

Heuchera ‘Citronelle’ was created accidentally by gardeners attempting to produce its close relative Heuchera ‘Caramel’. It is considered a Heuchera villosa hybrid and is native to the Southeast. Featuring vibrant citron leaves with silver undersides and cream-colored flowers, Heuchera ‘Citronelle’ is a colorful container plant perfect for gardeners looking to spice up their arrangements.

Like the Heuchera ‘Rose Quartz’, ‘Citronelle’ attracts butterflies, hummingbirds and bees, and it is deer resistant. Unlike its heat-resistant cousin, however, ‘Citronelle’ is more sensitive to sun and will experience color fading if placed in full sun. This species requires weekly watering, though more frequent watering may be necessary in extreme heat. Good drainage is essential, and the only pruning required is removing any winter-damaged leaves during the spring.

This bright yellow plant is well-paired with hostas (see our hosta preview here), and it can be used as an edge or container plant. It is easy to grow and complements most perennial arrangements. The leaves are low and form in clumps, making it the perfect plant for perennial borders. Heuchera ‘Citronelle’ is a cheery plant to brighten any summertime garden.
