Flowering this week is our 2019 seed collection from Texas of the Evening Primrose looking Milkweed, Asclepias oenotheroides. This odd clumping milkweed, which tops out at 18″ tall, only grows natively from Louisiana west to Arizona, and south into Mexico in very dry sites. Hardiness is most likely Zone 7b-10b.
As gardeners around the country are encouraged to plant more asclepias to encourage monarch butterflies, many folks are finding out that not all species of asclepias make good garden plants. As a genus, asclepias consists of running and clump forming species. There are number of horribly weedy garden plants like Asclepias speciosa, Asclepias syriaca, and Asclepias fasicularis. These plants are fine in a prairie garden, but are disastrous in more controlled home gardens.
One of our favorite clumping species is the easy-to-grow, Arizona-native Asclepias angustifolia ‘Sonoita’. This superb species was shared by plantsman Patrick McMillan. It has proven to be an amazing garden specimen, thriving for years, despite our heat and humidity. Did I mention it flowers from spring through summer?
This is the time of year when the tiger swallowtails feast on our many patches of the amazing native Stokes aster. Our favorite clone is the upright growing Stokesia laevis ‘Peachie’s Pick’. Moist soils are best, but stokesia tolerates some dry conditions on a short term basis as long as it has 2-6 hours of sun.
One of our Paeonia ostii seedlings flowered well for the first time this year, and turned out to be semi-double flower instead of the typical single flowers. We’ll continue to observe it in future years and make sure the trait is stable, but if so, this could be a lovely addition to the world of hardy tree peonies that tolerate heat as well as cold.
One of the little-known native asclepias, milkweed, is flowering in the garden this week. Asclepias variegata, redwing milkweed, is a widespread native, ranging from Canada and Virginia south to Florida, and west to Texas. So, why is this virtually unavailable commercially? Our plants typically range from 1.5′ to 2′ tall, although 3′ is possible. For us, it performs best in part sun to light shade.
The specific epithet “variegata” which refers to two colors on the flower was certainly a poor choice, since most asclepias have multi-color flowers. Of course, Linnaeus didn’t have the benefit of the internet back in 1753.
We wanted to create a buffet for local butterflies by our patio, and a mass planting of Eupatorium purpureum ‘Little Red’ did just the trick. Not bad for a highway ditch native.
The 7′ tall, and very floriferous Hedychium ‘Flaming Torch’ is looking quite stunning today in the garden. Although they are commonly called ginger lily, they are not a true lily (genus Lilium) or a true ginger plant (genus Zingiber). Hedychiums are prized for their summer and early fall floral shows atop bold-foliaged stalks. The inflorescences are quite exotic looking, resembling clusters of orchids. Slightly moist, rich garden soils and at least 1/2 day sun are best for these hardy tropical looking plants.
Baptisias, commonly known as false indigo, are North American native members of the pea family and quite drought tolerant once established. They provide amazing architectural form in a sunny garden or perennial border, and are deer-resistant and a butterfly magnet (See the top 25 flowers that attract butterflies here.).
Not only do baptisia come in blue, which many people are familiar with in the most common species, B. australis, but they are also available in a wide array of colors such as white, yellow, purple, and pink, and new breeding efforts are producing bicolor flowers such as those of Lunar Eclipse.
Baptisias have long been one of our favorite groups of sun perennials here at PDN. Through our trials of new varieties introduced to the market, as well as our own breeding program, we continue to select for improved structure and habit as well as flower color. In 2017, we have introduced 2 new varieties in our Tower Series, Yellow Towers and Ivory Towers. These join our previous introduction, Blue Towers, all having a vigorous upright habit to 4.5-5′, terminating in 18-20″ spikes of flowers, true show-stoppers in the garden.
Due to high demand, we quickly sold out of finished stock of Ivory Towers, but don’t fret, we have another crop coming along and they should be ready just in time for our Spring Open Nursery & Garden Days April 28-30 and May 5-7. And be sure to join us on Sunday May 7 at 2pm for our Gardening Unplugged garden chat series, where Tony will be talking about baptisias. You can also read Tony’s more in depth article about baptisias, here.
There are few times of year more exciting for us than lycoris (surprise lily) season, and we are right in the midst of that now. We’re also enjoying peak butterfly season at the same time, which is really great since butterflies love to drink surprise lily nectar. It’s hard to put the camera down with so many great photo opportunities, so we thought we’d share one of our favorites from this week…an Eastern Tiger Swallowtail on Lycoris x rosea. See the top 25 flowers that attract butterflies here.
We love plants that attract butterflies to the garden, and here at Juniper Level Botanic Garden, it’s been a banner year for butterflies. Allium ‘Millenium’ is always a favorite of yellow swallowtails…here are images from this week. See the top 25 flowers that attract butterflies here.
Joe Pye weed…aka Eupatorium is always a butterfly favorite. Here is a photo this week with yellow swallowtails taking a sip of Eupatorium dubium.
The pipevine swallowtails were enjoying the same eupatorium together with the yellow swallowtails. You can find a link to all of our butterfly favorites here. We hope you’ll plant to bring nature into your garden.
Looking especially great in the garden today is Buddleia ‘Blue Heaven’. This amazing butterfly bush was hybridized to have a perfectly rounded, compact shape throughout the growing season without any clipping. Here’s our amazing plant in the garden this week.
We know it’s hard for some folks to wrap their mind around being excited when insects eat your plants, but that’s how nature works. In the best scenario, the insect eating the plant is as beautiful or more so than the plant their eating. I just snapped this photo of the larvae of the Pipevine Swallowtail devouring all of our aristolochia (pipevines) in the garden. This actually doesn’t harm the plants, and before long, your garden will be filled with these beautiful butterflies below. No spraying, please. See the top 25 flowers that attract butterflies here.
I just snapped this photo yesterday in the garden of the native (Illinois south to Florida) Centrosema virginianum (butterfly pea) vine. We don’t currently offer this, but if we did, would you buy it? See the top 25 flowers that attract butterflies here.
One of my favorite foliage perennials is unquestionably Aristolochia fimbriata. While the flowers are insanely cool and produced all summer, the foliage is just so hard to beat. Even where it isn’t winter hardy, Aristolochia fimbriata makes a great summer container spiller, sprawling to about 2′ in width. Here’s how it looks in the garden today.

Greetings from Plant Delights. We hope all is well in your hometown. It’s that time of year and the fall catalog will be on the way on Friday, August 11. If you want to get a head start on your friends, you can find the new catalog on-line at www.plantdelights.com.
We hope you are making your plans to visit PDN this fall, either for the PDN fall open house or for the JCRA 30th Anniversary Symposium.
Even though we may cringe at the idea of summer gardens, there are quite a few plants that relish the idea. The gingers and the colocasias are loving the summer heat, and I can’t think of a plant that more represents summer than the wonderful hardy hibiscus, which are in full flower as we speak. August is a fun month, since this is when many of the wonderful lycoris (surprise lilies) flower. I usually don’t like surprises, but I always break my rule when it’s lycoris time. Another bulb that just loves summer weather is the crinum lilies with their amazing stalks of pink, red, striped, or white flowers.
There are so many summer butterfly-attracting plants flowering now, from the long-flowering verbenas to the stunning eupatoriums (joe-pye-weed), to the well known buddleia (butterfly bushes). Since butterfly attracting plants are designed to flower when butterflies are in season, most of the summer flowering plants are probably good nectar sources. We hope you’ll take time to journey through the pages of the new on-line catalog and see what fun plants you can’t live without.

On a sad note, we have lost one of our wonderful NC plantsman, Rob Gardener, to cancer. Rob retired from the NC Botanical Garden in Chapel Hill a few years earlier, after devoting his life to gardening and in particular to the genus Sarracenia. Other than many of the sarracenia hybrids we carry, Rob will also be remembered for two of his other introductions, Baptisia ‘Carolina Moonlight’ and Baptisia ‘Purple Smoke’. We’ll certainly miss a good friend and fine plantsman.
