Loropetalum, Loves and Lies

Posted on by

We’ve been fascinated with the woody plant genus Loropetalum since the late J.C. Raulston first distributed the pink-flowered forms, which had just come into to cultivation in the US, back in 1989. Since those original plants were propagated and sold, many nurseries have tried to one up each other with a barrage of new introductions. Today, we have documented 68 named cultivars of Loropetalum, of which we currently grow only 22. Below are a few from JLBG, which are currently in full flower.

Sadly, most folks mistakenly think these are foundation shrubs, thanks to unscrupulous retailers. Most, are in fact, either large shrubs or small trees. Yes, if you’re into plant mutilation as a form of legal S&M, you can shear them into bizarre boxes and meatballs, but do you really think this is a good idea? Do you really hate natural beauty that much?

Below are a few named selections with their advertised sizes and their actual sizes, so you can plant them in the proper place. Winter hardiness is Zone 7b-9b.

Loropetalum ‘Snow Panda’ has been truly outstanding for us. It was introduces as maturing at 10′ tall x 9′ wide, and our 7-year-old plant is now 7′ tall x 12′ wide.

Loropetalum ‘Zhouzhou‘ is sold as ‘Zhoushou Fuchsia‘ and as ‘Pipa’s Red’. These are listed as maturing at 5′ tall x 6′ wide and 12′ tall x 12′ wide, depending on which name is on the tag. The reality is that it matures at 30′ tall x 20′ wide, as you can see below with our 27-year -old specimen.

Loropetalum ‘Ruby Snow’ is a fascinating chimeral misfit (think schizophrenic) selection with both white and pink flowers. The introducer touts it as maturing at 6′ tall x 6′ wide, but our 6-year-old specimen is already 8′ tall x 14′ wide, so this will get far larger than the tags indicate.

Loropetalum ‘Daruma‘ is an extremely heavy flowering selection that is sold as maturing at 5′ tall x 5′ wide, but this isn’t even close. The 6-year-old specimen below is already 6′ tall x 9′ wide, and our oldest specimen had to be removed from its original location after it reached 16′ tall x 16’ wide.

Loropetalum ‘Shang Hi’, sold under the marketing name Purple Diamond, is touted as maturing at 5′ tall x 5′ wide. Ooops–our 14-year-old plant is already 15′ tall x 15′ wide. Perhaps we need to give remedial measuring courses to some of our nursery folks.

Loropetalum ‘GrifCRL‘, marketed as Little Rose Dawn, is incredible in flower, but it’s marketed as maturing at 10′ tall x 10′ wide, and our 16-year-old specimen is now 18′ tall x 18’ wide.

Loropetalum ‘Crimson Fire’ is much more red than most selections. The introducer claims it will mature at 4′ tall x 5′ wide, but our 6-year-old plants are already 10′ tall x 10′ wide.

These are just a few of the amazing selections, but keep in mind to never trust plant tags when it comes to where you should plant your plants to keep from needing to butcher them.. Until nurseries and plant introducers learn to care more about the end consumer’s success, it’s always a good idea to visit botanic gardens and determine the true size for yourself.

Stunning Townhouse

Lagerostroemia faurei ‘Townhouse’ is looking great at JLBG this summer. This compact selection was named by the late J.C. Raulston, in addition to the taller, narrower cultivar L. ‘Fantasy’. Townhouse crape myrtle is also highly prized for its dark cinnamon bark…the darkest of any crape myrtle we know. Our oldest specimen is now 35′ tall x 35′ wide.

This selection is from an original 1957 seed collection made by the late Dr. John Creech of the US National Arboretum, on Yakushima Island off the southern coast of Japan. Hardiness is Zone 6b-9b.

Cherry Bomb

The superb (and spineless) Ilex ‘Cherry Bomb’ is looking amazing in the garden this week. Our specimen is now 22 years old, and measures 35′ tall x 15′ wide. It originated at the US National Arboretum as part of Dr. William Kosar’s breeding program, and is a 1959/1960 seedling from Ilex ‘Nellie R. Stevens’, most likely a hybrid with the spineless Ilex integra.

It was sent around to different growers for evaluation trials under a code #, and was later determined to not have enough value for northern US growers, so a destruction notice was sent by the National Arboretum.

Like some characters in the slasher flicks, it wasn’t completely destroyed, as propagations from the holly managed, quite improperly, to make its way to the deep south, where growers found it quite extraordinary, and in the 1980s, it was given the name Ilex ‘Cherry Bomb’ by Dr. Dave Creech of Steven F. Austin University. This wonderful plant is now a staple in the Southern nursery industry.

Finally, a ferner adapts

Since ferns are one of the groups on which we focus our ex-situ conservation efforts, we have collected a huge number of species and selections from around the world. One that has continually frustrated us is the miniature rock fern, Asplenium trichomanes. Although this small gem is native to every continent except Antartica, we have struggled to keep it alive.

In our travels, we have collected it from Europe to Africa, but have also managed to kill all of those collections in the garden. Since our first attempt in 2004, we have now killed Asplenium trichomanes 16 times. We believe, however, in the late JC Raulston’s mantra, “Unless you are killing plants, you aren’t growing as a gardener.” The key is how many times do you continue to try before giving up?

We’re pretty stubborn as long as we feel we keep learning from each failure. Our latest accession of this species, which came as spores from Russia’s south coast, is actually thriving in our crevice garden, where the pH is north of 8.0. It seems that the crevice habitat is the answer.

High on Loquats

We truly love loquats…both to grow and consume. I first met Eriobotrya japonica in 1976 on a walk around the NC State campus with the late Dr. JC Raulston. I was amazed to see a mature 30’+ specimen growing against one of the campus buildings. I was determined to grow one of our own, so in the mid 1990s, we planted our first specimen here at JLBG.

Loquats, a Chinese native member of the rose family, makes a lovely small tree with large, evergreen foliage that resembles a corrugated Magnolia grandiflora. Another exceptional feature is the fragrant white flowers that start to open around Christmas. These are followed by delicious orange fruit in early spring, when winter temperatures don’t drop below the mid-teens F. Loquat foliage is also brewed as a tea, in addition to its numerous medicinal benefits. We have always found loquats to be much more winter hardy than most of the literature indicates. Our oldest specimen planted in 1997, has never experienced any winter damage. Hardiness is Zone 7b and warmer.

Kaizuka! Bless you.

I first met Juniperus chinensis ‘Kaizuka’ on a mid 1970s student field trip to Florida with the late JC Raulston. As our caravan of University vans crossed from Georgia into Florida, these junipers suddenly appeared everywhere. Although, I was unfamiliar with this architecturally fascinating specimen, I was in love….despite it being common as the proverbial dirt in Florida landscapes. Everywhere from gas stations to the poorest home seemed to have at least one. Most locals know Juniperus ‘Kaizuka’ as either Juniperus ‘Torulosa’ or Hollywood Juniper…a common name it gained due to its ubiquitous presence around Los Angeles. It turns out that Juniperus ‘Kaizuka’ was an introduction from Japan’s Yokohama Nursery prior to 1920. Our oldest plants at JLBG are now 33 years old, and now measure 24′ tall x 16′ wide. The one pictured below is a new 5 year old planting in a new section of the garden. Forty-five years later and still in love!

Proud to be a Siberian

We don’t have many Siberian plants which thrive in the southeast US, so we get pretty excited when we find one that does. I was introduced to Microbiota decussata by the late JC Raulston, back in the mid 1970s, and actually still have one of my original plants that’s still alive. Many years later, a much improved form came to market under the name Microbiota decussata ‘Prides’.

Microbiota is a monotypic genus of conifer that has a textural appearance somewhere between a Juniper and a Selaginella.  In the wild, Microbiota can only be found in one small region of the Sikhote-Alin mountains, which is about 500 miles north of Vladovostok, Russia, where it occurs between 6,500′ and 7,000′ elevation.

Although Microbiota was officially discovered in 1921, and published in 1923, the Russian government, long-known for its secrecy, kept it completely under wraps until the early 1970s.

Unlike most junipers, which need sun to thrive, microbiota prefers shade to only part sun. Consequently, it you like this texture and don’t have full sun, this is the plant for you. For us, it matures at 18″ tall x 6′ wide.

The Fragrance of Fall

Perfuming the garden this week are the amazing Osmanthus fragrans. This Chinese native evergreen shrub is unquestionably the most fragrant flowering plant in the garden. When the clusters of small flowers open early October, they emit a sweet fragrance that can easily waft for 200 feet. While we have nine clones in the gardens at JLBG, our oldest/largest two are Osmanthus fragrans ‘Conger Yellow’ (yellow flower) and ‘Aurantiacus’ (orange flower)…both pictured below.

Our sister institution, the JC Raulston Arboretum probably has the largest collection in the country of these amazing plants. For those old enough to remember, Osmanthus fragrans was a personal favorite of the late Dr. JC Raulston. If you are looking to purchase plants and can’t find them locally, our friend Ted Stephens, who runs a SC mail order nursery certainly has the largest offering in the country of these amazing plants.

Bushy Muhly

I fell in love with the Arizona/Mexico native ornamental grass, Muhlenbergia dumosa when the the late JC Raulston first brought it back from Yucca Do Nursery in 1992. This odd member of the genus muhlenbergia resembles a clumping bamboo unlike other members of the genus. For those non-connoisseurs of Latin, dumosa means “bushy”.

JC touted this Yucca Do collection from Northern Mexico as the most amazing ornamental grass he had ever encountered. JC distributed it to nurserymen, who introduced it into the trade, only to find out that it wasn’t winter hardy in most of North Carolina.

On a visit to the South Carolina Botanical Garden last year, we were shocked to see Muhlenbergia dumosa growing happily in their desert garden. It turned out that they were growing a new clone, collected from a higher elevation in Arizona, that had proved reliable in their Zone 7b climate. We were gifted a start of Mulhlenbergia dumosa ‘Patagonia’, which now resides in a couple of locations at JLBG. We’re very excited, and now look forward to having a cold winter to fully test its winter hardiness.

Celebrating Ferners

One of the fabulous ferns in our garden during the summer months is the sun-tolerant Dennstaedtia hirsuta ‘Sohuksan’. This fabulous specimen came to the US from a 1985 collection from Sohuksan Island, South Korea, where it was discovered by a team of intrepid plant explorers that included horticultural legends as Barry Yinger, the late Ted Dudley, the late J.C. Raulston, the late Peter Wharton, Young-june Chang and Kun-so Kim. The group had left the mainland for the several day ferry ride to this remote island, landing just ahead of a typhoon, which resulted in severe injuries disembarking from the ferry. After riding out the typhoon in minimal shelters, they awoke to a treasure trove of amazing plants. We are so glad to keep the memory of this amazing trip alive in gardens with some of their great plant introductions.

Here’s a recent combo at JLBG with Eucomis comosa ‘Sparkling Burgundy’ (our first plant introduction), paired with Hemerocallis ‘Prize Picotee Splendor’ (introduced by our friend Roy Klehm), and backed with Lagerostroemia faurei ‘Townhouse’, an introduction from our mentor, the late J.C. Raulston. For us, it’s about the plants and the people!
