I’d grown quite a few eryngiums…49 different ones, in fact, before Patrick shared Eryngium ravenelii with us in 2015. Who knew we were missing one of the best eryngiums in the entire genus! Today, Eryngium ravenelii holds several places of honor in our garden, where we can watch the myriad of pollinators who regularly stop by for a nectar snack during flowering season (mid-August to late September).
Eryngium ravenelii was named for American botanist, Henry William Ravenel (1814-1887). In the wild, Eryngium ravenelii grows in standing water in flooded ditches, alongside sarracenias (see bottom photo). We’ve now seen them in the wild in both North Florida and South Carolina, where they grow in calcareous-formed soils. In the garden, they thrive in an array of slightly acidic soils as long as the soil is reasonably moist.
We were saddened this past week to hear of the passing of our friend, Dr. Larry Mellichamp, age 73, after a three year battle with bile duct cancer. I first met Larry in the late 1970s, when he spoke to our Horticulture Club at NC State. Over the next 45 years, we interacted regularly, mostly during his visits to JLBG.
Knowing that Larry was in the battle of his life, we visited him at his wonderful Charlotte home garden last year (photo below). Even while he was ill, his wit remained razor sharp, and his humor as dry as the Sahara desert.
Not only did Larry teach for 38 years (1976-2014) at UNC-Charlotte, but he also managed the 10-acre UNC Charlotte Botanical Garden, which he turned into a must-see horticultural destination. Larry was a huge advocate of interesting plants, especially US natives. He was constantly dropping off new plants for us to propagate and share with a wider audience.
Larry was best known worldwide for his work with carnivorous plants, particularly with the genus Sarracenia. His “little bug” series, (Sarracenia ‘Lady Bug’, ‘June Bug’, ‘Love Bug’, and ‘Red Bug’, released in 2004, was the first widely marketed collection of pitcher plants, from his breeding work with the late Rob Gardener. In 2021, Larry was the recipient of the Lifetime Achievement Award from the International Carnivorous Plant Society…one of many such awards Larry received.
Larry was also a prolific writer. His books include: Practical Botany (1983), The Winter Garden with Peter Loewer (1997), Wildflowers of the Western Great Lakes Region with Wells/Case (1999), Bizarre Botanicals with Paula Gross (2010), Native Plants of the Southeast (2014), and The Southeast Native Plant Primer with Paula Gross (2020).
Larry and I connected on many levels, but we were both strong advocates for making rare native plants available for propagation and commercialization…something that is sadly the exception in the current world of botany. We hope others in the native plant community pick up the torch.
Larry is survived by his wife of 48 years, Audrey, his daughter, Suzanne, and a host of plants he spread throughout the world. Life well lived, my friend.

One of the little-known of the native orchids is flowering now at JLBG. Habenaria repens, aka: water spider orchid, is the most widespread (NC to Texas) of the five native habenaria species. This charmer has been at home in one of our bogs for several years and has proven quite easy to grow. Hardiness is probably Zone 7b-10a, at least.
Our clump of the native, Sabatia kennedyana just finished another amazing floral show. This fabulous, but easy-to-grow perennial has a truly odd native distribution on the coastal border of North and South Carolina, on the coastal border of Massachusetts and Rhode Island, and in Nova Scotia! I don’t think I’ve ever seen such an odd, disjunct range. Sabatia kennedyana is best suited for a sunny, slightly acidic bog, but regular garden soil will work fine, if it’s kept moist. I have no idea why this isn’t grown in every garden that has the correct conditions. Winter Hardiness is Zone 6-8, at least.
In case you missed this section of the garden during spring open house, this is where we created a small vignette that comprises both bog and desert conditions in the same space. The low central area was created for pitcher plants and other bog lovers, while the higher areas to each side, are home to dryland loving plants like agaves and bearded iris. We hope to show how dramatically diverse habits can be created in a very small space. The wet space is created by installing a seep, which is nothing more than a continually dripping water line.
I love odd plants, and the southeast native Lachnocaulon (pronounced lack no colon) is about as odd as they come. This bog native, often found growing with pitcher plants, forms a mound that looks like a giant pin cushion. Here is a plant of Lachnocaulon anceps (NC west to Texas) in full flower this week at JLBG. Yes, those white round balls are the flowers.
Looking good in the garden this week is the amazing fern, Dryopteris x australis. This rare fern is a US native…despite the confusing name, hailing from only a few scattered locations from Virginia west to Arkansas. In reality, the name “australis” means from the south. This splendid specimen grows in both sun and shade, and tolerates both wet and dry soils. Hardiness is Zone 5a-9b.
Here is a small sampling of the amazing array of flowers that are in the garden currently (late April/early May) on our pitcher plants. The genus Sarracenia is native to North America and hails from Canada south to Florida, where they are found in seasonally damp bogs. In the garden or in containers, they are incredibly easy to grow as long as they have moist toes (roots), and dry ankles (base where the crown meets the roots). Winter hardiness varies based on the species, but most are hardy from zone 5a to 9b.
Iris ‘Gerald Darby’ is one of those iris that doesn’t even need to flower to be garden worthy. Here it is in our garden this week, emerging with its’ purple leggings. This gem is a North American native hybrid of Iris versicolor and Iris virginica, known as Iris x robusta. This introduction of Iris breeder Gerald Darby was actually named for him after his death by another iris breeder R.H. Coe of England. Iris x robusta ‘Gerald Darby’ is equally at home growing in standing water as it is in typical garden soil. Hardiness is Zone 4a-9b.
Ever since I was a small kid, I’ve observed Zephyranthes atamasco (atamasco lily) in the wild, where they grow in swampy wooded lowlands. Atamasco lily is also one of many great nomenclatural muddles with regard to it’s correct spelling. When it was first named by Linneaus, back in 1753, it was assigned to genus amaryllis, so the specific epithet was spelled “atamasca”.
In his later work, Linneaus changed the spelling to “atamasco”, which corresponded to the Native American name for the bulb. It remained spelled with an “o” even after it was moved into the genus Zephyranthes in 1821. The problem is that, according to International Nomenclatural rules, the original spelling must take precedent. So, Zephyranthes atamasca is correct. Except…there is an exemption for name conservation, when correcting the name will cause confusion or economic harm. There is currently a well-supported move underfoot to conserve the long-used spelling “atamasco”. And you thought nomenclature was boring!
I’ve long marveled at the diversity within the species, and as an adult have been fortunate to be able to collect offset bulbs from some of the special forms I’ve found.
The top image is a very compact form that we’ve named Zephyranthes ”Milk Goblet’. Below that is one of our larger flowered forms from Alabama that we named Zephyranthes ‘Hugo’. Hugo has 5″ wide flowers in a species where 2.5-3″ wide is typical. Both of these are in full flower now at JLBG.
Raise your hand if you’ve grown macbridea in the garden. Raise your hand if you’ve even heard of macbridea. This cute North American native (NC, SC, GA) bog mint has really impressed us in the garden. Flowering started in the last few weeks, and shows no sign of abating. We’re always cautious with mint relatives, but so far, this one has been very well behaved.
The NC native Polygala aurea is putting on quite a show in the bog garden here at JLBG. There are few plants, native or otherwise, with such brilliantly screaming orange flowers. Perhaps we need to see if we can propagate this since we never see it offered for sale.
Flowering now at JLBG is one of our cute Southeastern natives known as Bog Buttons (Lachnocaulon anceps). The entire family, Eriocaulaceae, has a similar stature with small grass-like foliage, topped by these long antennae-looking structures. In the wild, these can be found in low, often flooded ditches, but they are easily grown in constructed bog gardens. I expect if these were from a more exotic location, more people would grow them. We think they are pretty darn cute.
Spring 2021 marked our first flowering of the monotypic (only one member of the genus) helonias. This threatened US native, occurs in scattered locations from NY south to Georgia, but is rarely offered commercially. We had good seed set, and now fingers are crossed for equally good germination. Helonias requires saturated ground, and ours is now thriving with pitcher plants and other moisture lovers. Hopefully one day, propagation will allow us to share this gem.
If you have a soggy area or damp soils, don’t drain it! We have marginal aquatic perennial plants for wet soil that are great for landscaping everything from rain gardens to bog gardens. These garden perennials love moist spots and will make you fall in love with perennials that dry soil gardeners only dream of growing. Damp soil plants range from carnivorous plants like sarracenia and bog plants like hymenocallis that need full sun.
Many bog plants like sarracenia also do well in containers as long as they retain consistent moisture. Click here to learn more about their culture and growing sarracenia in containers.
