Most of us plant geeks marvel at the genetic diversity of plants as we drive, and one of my passions is studying the incredible diversity our our native red cedar, Juniperus virginiana. Below is an exceptional been pole-like form, Juniperus virginiana ‘Taylor’, selected from a population in Taylor, Nebraska, and released in 1992 by the Nebraska Statewide Arboretum. Mature size should be around 20′ tall x 4′ wide. Our plants below are five years old.
We have really enjoyed the sprig foliage show of Osmanthus fragrans ‘Qiannan Guifei’ for the last few weeks. This spring-emerging variegated foliage adds a whole new level of “wow” to the sweetly fragrant tea olive shrub, Osmanthus fragrans. This new selection, introduced from China to the US by our friend Ted Stephens of Nurseries Caroliniana, is from Qiannan-based plant breeder, Tan Zhi-ming. Winter hardiness is Zone 7b-9b.
We’ve long been a fan of the central Japan native conifer, Thujopsis dolobrata, which we’ve grown for decades. For those, who aren’t students of the Latin language, the ending -opsis, means “looks like”. When Thujopsis was formally named in 1894 by Franz von Siebold and Joseph Zuccarini, they chose a name that could be translated to “looks like the American genus, Thuja”.
On a 2012 trip to Joann Currier’s former Unique Plant Nursery in NC, we noticed a plant of Thujopsis that looked unlike any we’d seen. Since the genus only has a single species, the variant was either a mutation or odd seedling. The very thick, plastic-like foliage on this selection gives the appearance of a ploidy mutation (extra chromosomes).
The cutting they shared was rooted, and subsequently went in the ground here in 2013. A decade later, our plant is pictured below this month, topping out at 10′ in height. Joann originally got the plant from Randy Plante at Greener Visions Nursery, who got it from NC conifer nurseryman Geoff Driscoll, who got it from someone “up north”. That’s where the trail goes cold. We’ve shared cuttings with several NC nursery folks, in the hopes this amazing selection becomes more commercially available in the future.
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.
Here’s one of our favorite hollies, looking great in the garden this week. Ilex integra ‘Green Shadow’ is a variegated (creamy-edged leaves) form of the Mochi holly. This amazing columnar holly, that hails from oceanside mountain slopes in Japan, Korea, Southern China, and Taiwan, reaches 20′ tall x 7′ wide, which is the case with our 16 year old specimen. Although Ilex integra ‘Green Shadow’ will grow in both sun and shade, full to half day sun results in the most dense foliage. This is female clone, but we never see more than a dozen berries, so we assume it needs a male nearby to fruit better. For a narrow evergreen screening plant, it’s hard to beat. Hardiness is Zone 6b-9b.
