The variegated wide-leaf holly, Ilex latifolia ‘Snow Flash’ is loaded with berries and looking quite spectacular in the garden this month. We’ve shared cuttings with several nursery folks, so hopefully, this will be making its way into the market. The plant was originally brought to the US from Japan by plantsman Barry Yinger. Our specimen below is now 18 years old. Hardiness is Zone 6a-9b.
Ilex ‘Magiana’ has made a superb plant in our garden. Below is a photo this week. This 2003 introduction form Mississippi’s Evergreen Nursery has never been touched by a pruner. The patent expired this year, so we anticipate more nurseries will be propagating it in the future. It originated as a seedling of Ilex ‘Mary Nell’ and was originally sold under the trademark name Acadiana. In the garden, expect a mature size of 14′ tall x 8′ wide. Our specimen is now 16 years old.
Looking wonderful in the garden this week is Ilex x attenuata ‘Pack’s Weeping’. This superb, but almost unknown cultivar, is a selection of the naturally occurring North American native hybrid of Ilex cassine x Ilex opaca, and was selected by Alabama’s Pack’s Nursery. Foster’s holly is prized for being parthenocarpic (produces fruit without the need for a male pollinator).
I’m just back from a recent plant trip to coastal Virginia and wanted to share some trip highlights and photos. Mark Weathington of the JC Raulston Arboretum and I headed north for a quick 2 day jaunt to the Norfolk area of Virginia.
Our first stop was the garden of long time garden friend, Pam Harper. For decades, Pam was probably the most prolific and knowledgeable garden writer in the country, in addition to having what was once the largest horticultural slide library.
At 92, and despite suffering from debilitating eyesight issues, Pam still gardens, including planting and pushing carts of mulch around the garden. It was such a joy to once again walk her amazing garden, listening to the both the historical details and performance of each plant we passed.
Pam was donating the remainder (20,000) of her slide collection, which previously numbered over 100,000 images, to the JC Raulston Arboretum. There, they will be digitized for public availability.
Her 45 year-old Camellia sasanqua ‘Yuletide’ was the largest either of us had ever seen.
We both also fell in love with Camellia x vernalis ‘Meiko Tanaka’…a plant we’d never encountered in flower, but seems to have good commercial availability.
The gold barked Japanese maple, Acer palmatum ‘Bihou’ was also showing off its stunning winter color.
Pam’s garden has always yielded some of the most amazing Arum italicum seedlings I’ve ever seen. We are already growing two of her selections in hopes of future introduction, but we found a few more that we couldn’t resist.
Our next stop was the Virginia Tech Tidewater Arboretum at the Hampton Roads Experiment Station. It had been many years since either of us had visited.
What we found was an amazing plant collection that has been mostly abandoned, except for some minimal mowing maintenance. In most cases the labeling was somewhat intact, although some required Easter egg-like hunts, and others were simply nowhere to be found.
The late Virginia Tech researcher, Bonnie Appleton had worked to get homeowners to plant shorter maturing trees under power lines. To make her demonstration more authentic, she had faux power lines installed, which you can make out among the branches. It was interesting to see that virtually all of the plants she promoted as dwarf, had all grown well into the power lines. Mark recalled conversations with her decades earlier explaining that her choices weren’t really very sound.
There were a number of amazing older specimens including one of the largest Quercus polymorpha (Mexican Oak) that we’d ever seen in cultivation. This 75′ tall specimen dated to 1989, was originally gifted to them by the late JC Raulston, from a Yucca Do Nursery wild collection.
The old specimens of Ilex buergeri were absolutely stunning. This is a beautifully-textured, spineless broadleaf evergreen that’s virtually unknown in the commercial trade.
Another spineless holly, Ilex pedunculosa (long-stalk holly), is known for being difficult to grow in our hot, humid climate. Their specimen, however, looked absolutely superb.
We caught Fatsia japonica in full flower…always a great nectar source for honeybees in the winter months.
A highlight for me was catching the amazing stinkhorn fungus, Clathrus columnatus in full splendor…both visually and odoriferously.
Leaving the Hampton Roads station, we headed to the Norfolk Botanical Garden, where Mark worked before he came to the JCRA. Much of their efforts in the fall and winter are put toward their massive winter lights festival.
Norfolk Botanical Garden is home to an extensive and renown camellia collection, so we spent a good bit of time roaming the woodland garden where they grow. We were particularly interested in their Camellia species collection, several of which had questionable labeling. Here is one that was correct, Camellia gaudichaudii.
We spent a good bit of time studying a holly, labeled Ilex purpurea (syn. chinensis). The plant was amazing, but looks nothing like that species. Hopefully, a holly expert will be able to help us identify it from our photos.
This was my first time seeing the self-fertile idesia, Idesia polycarpa ‘Kentucky Fry’. I can’t imagine why this amazing, easy-to-grow plant isn’t more widely planted. I can think of few trees with more winter interest.
The shrub/small tree that blew us away from several hundred feet was a specimen of Arbutus unedo ‘Oktoberfest’. We’ve grown Arbutus unedo ‘Compacta’ for decades at JLBG, but have never seen anything as stunning as this clone.
While we’re talking about plants with red fruit, I was fascinated with their specimen of Cotoneaster lacteus. I had mistakenly assumed that most cotoneasters fail in our hot, humid summers, but obviously, I’ve never tried this species, which is typically rated as hardy only to Zone 8a. I think we need to trial this at JLBG.
Finally, I was particularly fascinated with a Quercus nigra (water oak), that formerly had a planter built around it’s base. As you can imagine, the tree roots made short work of the planter, but once the planter boards were removed, the resulting tree root sculpture is simply exquisite.
I hope you’ve enjoyed the highlights of our recent trip.
You remember the rest of the line…with boughs of holly… Here’s one of many amazing hollies looking great today. Ilex ‘Conty’ has been a fabulous performer in our garden here in Zone 7b. This holly selection was discovered in Mississippi’s Evergreen Nursery in 1989, as a open pollinated seedling of Ilex ‘Mary Nell’. The mom, Ilex ‘Mary Nell’, is a holly hybrid that originated as a controlled cross of Ilex cornuta × Ilex pernyi ‘Red Delight’.
Our plant, pictured below is 11 years old that has never seen a hedge shear. Mature height is 15-20′ tall x 12-15′ wide. The natural form is incredibly dense with a good fruit set. Commercially, this was marketed under the name Liberty holly, which is a proprietary trademark name. The actual cultivar name is Ilex ‘Conty’. Learn more about the misuse of trademarks in horticulture.
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.
I just snapped this garden image of the amazing gold-leaf holly, Ilex ‘Whoa Nellie‘…a sport of Ilex ‘Nellie Stevens’…simply superb! Even though we don’t usually sell shrubs, we propagate a few of these each year since I love ’em so much.
