Container Gardens for Summer Color

吉吉影音成 人影院6655Add summer color to your patio, pool or deck with perennial container gardens. There are many great summer blooming perennials that work well in containers and provide a pop of color even if you have limited garden space to plant. There are many types of containers that can be used and left outside year round. The containers shown here are a resin material that is weather resistant and come in an array of sizes and colors that can fit into any decor. These containers may need to have holes drilled into the bottom for drainage, and many have punch-out holes. They are light-weight and are easily moved even after planting. There are also ceramic and concrete planters that are frost proof and available in every conceivable shape, color and size.

Colocasia, perennial Hibiscus, Sarracenia (pitcher plants) and Bletilla

吉吉影音成 人影院6655Some colorful and long blooming summer perennials you may want to consider for your containers include colocasia, perennial hibiscus, cannas, verbena, flowering maple, dahlias, monarda (bee balm), and daylilies. Other evergreen and variegated perennials can be grown in containers as well, such as aspidistra (cast iron plants), agave, mangave, and cacti. Hostas also make great container plants for the shady spot on your patio.

Canna ‘Orange Punch’, Verbena peruviana, perennial hibiscus and abutilon (flowering maple).

It is important to consider plant hardiness when creating your planter. Remember that since the plants roots are above ground and not insulated, they will be subjected to colder air temperatures during the winter. Depending on the length and severity of the winter, some plants may be just fine through the winter, or your container garden may benefit by being brought into the garage, sun room or porch area during the winter, or situated in a micro-climate, like next to a south facing brick or stone foundation.

Kale by the Sea

When we finally discovered that sea kale (Crambe maritima) is indeed growable in our hot, humid climate, we’ve planted it all around. It’s also been rewarding that people have actually purchased it to try for themselves. Frankly, I’d grow sea kale for the ornamental value alone…a perennial with blue waxy foliage and an incredible show of white flowers in spring!Then, there’s the edibility, both cooked and raw. Also, for us, unlike other cabbages and kale, it has been virtually untouched by the pesky cabbage loopers.

Here is a photo of sea kale in our crevice garden this April, growing in a soil mix that’s 50% gravel, with no summer irrigation. Read my lips, I mean text…full baking sun and no irrigation after establishment. We recommend you never let your plants read the repetitive on-line sites that all tout that it only grows in cool, moist, climates…hooey!

Got the blues?If not, we can help.

Amsonia (aka: bluestar) are one of the best temperate genera (18 species) of blue-flowered perennials for the spring garden. We’ve offered quite a few different species and selections through the years, rotating them in and out as propagation successes allow and as sales dictate. All but two of the species, (Amsonia orientalis from Europe and Amsonia elliptica from Asia) are North American natives. Most are extremely drought tolerant, while others like Amsonia rigida and Amsonia tabernaemontana can tolerate very wet soils.

Amsonia montana is a commonly grown plant of mystery, having just appeared in horticulture, but never been documented from a wild population. A few of the amsonia species have flowers so pale blue that they appear white in the garden with only a hint of blue on the flower corolla. Amsonia are quite promiscuous in the garden, so if you grow more than one species nearby, you will have hybrids from seed. We hope you’ll explore this amazing genus of perennials.

Loss of a Phalloid Legend

We are saddened to announce the passing (May 12) of one of our closest friends, plantsman Alan Galloway, age 60. In addition to serving as an adjunct researcher for Juniper Level Botanic Garden, Alan was a close friend and neighbor, living less than two minutes from the garden/nursery.

Alan was a native North Carolinian, who grew up on a farm in Brunswick County, NC, where he developed his love for plants and the natural world. After graduating from UNC-Wilmington with a Computer Science degree, and working for his alma mater for two years, he made the move two hours west to Raleigh. There, Alan worked at NC State University in IT administration and management for 30 years, until retiring in Fall 2018 as Director of IT Services.

Starting in 1999, Alan would save up his vacation time from his day job at NC State, and spend 3-4 weeks each fall, trekking through remote regions of the world where he felt there were still undiscovered aroid species to find, document, and get into cultivation. From 1999 to 2018, he managed 21 botanical expeditions around the world, that included the countries/regions of Cambodia, Crete, Hong Kong, Laos, Mallorca, Philippines, Thailand, and Vietnam.

Alan routinely risked life and limb on his travels, whether it was getting attacked by a pit viper in Thailand, barely missing a land mine in Cambodia, or tumbling down a mountain and almost losing a leg in Laos.

I had the pleasure of botanizing in Crete, Thailand and Vietnam with Alan, which was an amazing experience, although not for the faint of heart. Alan was?a tireless force of nature, but was not one to suffer what he viewed as stupidity or laziness.?Although he was very respectful of people from all walks of life, he also regularly burned bridges to those whom he found incapable of meeting his meticulously high standards.

Alan was botanically self-taught, but his obsessive compulsion led him to become one of the worlds’ leading experts on tuberous aroids, specializing in the genera Amorphophallus and Typhonium. To date Alan is credited with the discovery of 30 new plant species (see list below). He was working on describing several more plants from his travels at the time of his death.

Not only did Alan’s botanical expeditions result in new species, but also new horticultural cultivars of known species. Two of the most popular of these were Leucocasia (Colocasia) ‘Thailand Giant’ (with Petra Schmidt), and L. ‘Laosy Giant’.

As a scientist, Alan was both meticulous and obsessive. It wasn’t enough for him to observe a new plant in the field, but he felt he could learn far more growing it in cultivation. He would often work through the night in his home research greenhouse studying plants and making crosses, so he could observe seed set and determine other close relatives.

Alan was overly generous with his knowledge, believing that sharing was necessary for the benefit of both current and future generations of plant scientists. Without his expert understanding of crossbreeding tuberous aroids, we would never have been able to have such incredible success in our own aroid breeding program. Seedlings from his crosses were then grown out and observed, often resulting in a number of special clonal selections.

After his tuberous aroids went dormant each year, all tubers were lifted from their containers, inventoried, and carefully cleaned for photography and further study. Visiting his greenhouse during tuber season was quite extraordinary.

In his amazing Raleigh home garden and greenhouse, Alan maintained the world’s largest species collection of Amorphophallus and Typhonium, including 2 plants named in his honor; Amorphophallus gallowayi and Typhonium gallowayi. Alan’s discoveries are now grown in the finest botanical gardens and aroid research collections around the world.

After returning from what proved to be his last expedition in Fall 2018, he suffered from a loss of energy, which he attributed to picking up a parasite on the trip. It took almost eight months for area doctors to finally diagnose his malaise as terminal late stage bone cancer, during which time Alan had already made plans and purchased tickets for his next expedition. I should add that he made his travel plans after being run over by a texting pickup truck driver, and drug under the truck for 100 feet through the parking lot of the nearby Lowes Home Improvement, which ruined his kidney function.

Alan was certain, albeit too late, that his cancer came from a lifetime addiction to cigarettes, which he was never able to overcome. Over the last 18 months, it’s been difficult for those of us who knew Alan to watch him lose the vitality and unparalleled work ethic that had been his trademark. Despite his loss of physical ability, his trademark independent/stubborn nature would still not allow him to even accept help driving himself to chemo infusions and blood transfusions, which he did until he passed away. Alan was also never one to complain or bemoan his circumstances, only continuing to accomplish as much as possible in the time he had remaining.

After the initial shock of his diagnosis, Alan systematically began distributing massive amounts of his ex-situ conservation aroid collection to gardens and gardeners around the world, since he also believed that sharing is the most effective means of plant conservation.

One of his hybrids that Alan had shared and asked us to keep a special eye on was his cross of Amorphophallus kachinensis x konjac. We talked with him last week and shared that the first flower was almost open, and he was so excited to see his baby for the first time, but by the time it opened early this week, it was too late. So, here is the photo of his new cross, seen for the first time that would have made him so proud.

Not only has Alan been a good friend for over 30 years, but he has been extremely generous in sharing with us at PDN/JLBG. Over 1500 plant specimens in our collection came directly from Alan. It still seems surreal that we have lost such a vibrant soul that has been so important to expanding our body of knowledge about the botanical/horticultural world. Farewell, my friend…you will be sorely missed.

We will be coordinating with his niece April and her husband Mark to plan a celebration of Alan’s life, which will be held here at PDN/JLBG at a future date, which we will announce when it is set.

Oh Cezanne, Don’t You Cry For Me

Ok, the spelling of “Susanna” is slightly different, but don’t let that deter you from growing one of the greatest groundcover clematis that we’ve ever grown. Yes, that’s right…no mailbox post or staking required. We’ve been growing this amazing, compact clematis as a groundcover for years and it is truly superb.Here it is in the garden this spring, but it will also continue to flower into summer.What’s not to love about Cezanne!

Done goneii or Gone dunnii?

Amorphophallus dunnii has long been one of the stars of the winter-hardy love lily clan, but now we’ve gone and really “dun” something even more odd. Amorphophallus dunnii is in flower right now in the garden with it’s typical 1′ tall peculiar, but fragrantless flower spike. This year for the first time, our collection of Amorphophallus dunnii from Lai Chau in North Vietnam flowered, and we were thrilled to measure it at just over 3′ tall. The super-sized petiole and leaf last summer gave us a hint of what was to come. Evidently plants from this region in North Vietnam are dramatically taller than those of the same species from mainland China. We are now working to vegetatively propagate this special form so that we can share it in the future.

Who needs Viagra when you’re Soo hot?

Last week, I was innocently feeling up the spadix on our flowering Sauromatum, when I noticed it was incredibly hot…not in the biblical sense, you understand. We grabbed our newCovid thermometer to take its temperature, and with an ambient outdoor temperature of 61 degrees F, our Sauromatum spadix registered 96.3 F….that’s a 35 degree F fever!

In the plant world, this “fever” is known as thermogenesis. Pretend you’re a plant, and a pretty homely one at that. You’re ready for the big once-a-year moment and are probably wondering if you’ll get lucky in the short time window that your sexual parts will be functional. You also know you were born with an aphrodisiac to help you get laid, but it’s only good if you can get the word out. That’s where thermogenesis comes in handy. Many members of the aroid family (think anthurium and philodendron) were born with the ability to crank up the temperature in their sexual regions to disperse the fragrance of their aphrodisiac. In the case of aroids, that would be the smell of rotting flesh. Once our sauromatum got the heat going, there was a steady stream of incoming flies looking to get laid. Actually, they were looking for food and got tricked into satisfying the desires of our horny sauromatum. Isn’t nature amazing!

Shoulda, Coulda, Woulda Bought a Sedge

Back in 2004, I was botanizing in rural Bienville Parish, Louisiana, where I ran across this fascinating narrow-leaf native sedge, a small piece of which returned home for trials.After six years of trialing, we named it Carex retroflexa ‘Bonnie and Clyde’ (alluding to the location where the famous pair met their demise) and added it to our catalog offerings, where it sold a whopping 150 plants over a four year span, ending in 2013.The term “whopping” is used here as a point of sarcastical understatement.Not wanting to discard all of the unsold plants, we planted them around our new patio, where they were interspersed with Heuchera ‘Smoke and Mirrors’ and Penstemon ‘Blackbeard’.Here are a few images from that planting, taken this week.Maybe as the interest in carex increases, we can afford to offer this again.

A Fairy Wing and a Prayer

Epimediums have long been a staple of the woodland perennial garden, but it wasn’t until plantsmen like Darrell Probst (US) and Mikinori Ogisu (Japan) began discovering and sharing the amazing wealth of unknown Chinese fairy wing species that their popularity began to take off.

It wasn’t until 1998 that epimediums begin appearing in the Plant Delights catalog, because before that time, the available horticultural offerings just weren’t that impressive.Plants like Epimedium x youngianum ‘Niveum’ are just hard to get excited about…if you’ve got much of a horticultural pulse.Sadly, that’s still the most dominant choice at most garden retailers.

Epimedium x youngianum ‘Niveum’

Another reason epimediums have been slow to become mainstream is the difficulty in getting good images. Because epimediums are so three-dimensional and prone to flutter in the wind, it takes quite an effort to take good images.Single flower closeups, which are much easier to take, always make me skeptical about how nice the entire plant will look in the garden.

When we were preparing to offer epimediums for the first time, we were faced with the decision of which of the three common names to use; fairy wings, barrenwort, and horny goat weed. Well, it doesn’t take much marketing savvy to choose from that list. That said, if we’d known that porn megastar Ron Jeremy would soon have his own line of epimedium tablets for male enhancement purposes, we might have reconsidered.

PDN/JLBG epimedium trials and study area

Once we became enamoured with fairy wings, we did as OCD people are prone to do, and built an entire research structure for the study, development, and trial of epimediums. We currently grow over 330 different epimedium taxa…some for study, some for conservation, and some which have enough garden value to share. It usually takes us about five years to fully evaluate a new epimedium seedling, comparing it to all other varieties on the market.

Since 2000, we’ve introduced over 27 of our own epimedium selections with more in the queue.Here are a few that we’ve already introduced that have proven to be excellent performers.We hope you’ve tried them all.

So, what’s next? Here’s a sneak peak of some of selections that have passed the final stages of in-ground trialing and are ready to head to container production trials. Our standards include good garden vigor, good floral showiness, and uniqueness from all other epimediums on the market. We like to think our standards are pretty high. We’d love to hear which of these future introductions below are your favorites.
