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.
Most everyone is familiar with Blue rug juniper…aka: Juniperus horizontalis ‘Wiltonii’, but few people know its dwarf cousin, Juniperus horizontalis ‘Pancake’. This amazing selection of the North American native groundcover is much slower growing, shorter, and with much finer textured foliage. Here is a recent photo of this amazing plant in the gardens at JLBG. Why is it that we never see Juniperus horizontalis touted for native plant gardens…hmmm?
Our 4.5 year old clump of Rosmarinus ‘Arp’ has become ridiculously large, as rosemary does. When we moved to our new home, Anita requested one near the kitchen door, which was a no-brainer since I am in love with both her and her rosemary chicken. Rosmarius ‘Arp’ has been one of the most winter hardy of all rosemary cultivars we’ve trialed.
We expect most everyone has grown a hibiscus at one time or another, either tropical or hardy. How many of you have tried the Asian Hibiscus hamabo? This fascinating 8-10′ tall evergreen shrub has thrived in our trials since 2018, and is just now flowering at JLBG for the first time. We had always considered this species tropical, so we were thrilled to hear that it survived as a die back at the SFASU Arboretum in Texas after this springs’ arctic blast of -4F. Dr. Dave Creech at SFASU tells me that it remains evergreen down to 10 degrees F. Has anyone else had experience with growing this outdoors in a cold winter climate?
While folks from “up north” know yews (Taxus), they are far less likely to know its doppleganger, the false yew (Cephalotaxus). I’ve always considered the two fairly interchangable, so was fascinated when DNA showed they actually belong to different plant families, which aren’t really closely related…other than both being conifers. Taxus is now in its own family, Taxaceae, and Cephalotaxus now resides in its own family, Cephalotaxaceae. For most gardeners, the important thing to know is that deer will consume taxus, but not cephalotaxus.
Below are a few favorites from the JLBG gardens. Cephalotaxus harringtonia ‘Brooklyn Gardens’ is a much wider leaf plant than the better known Cephalotaxus ‘Duke Gardens’. Mature size of ‘Brooklyn Gardens’ is 2′ tall x 14′ wide, so it functions as an evergreen ground cover in either light shade or sun.
Our oldest plant of Cephalotaxus ‘Duke Gardens’ is now 27 years old, and measures 3′ tall x 12′ wide. Here it is growing in fairly deep shade.
Cephalotaxus harringtonia ‘Golden Dragon’ is a much smaller selection with bright golden foliage. Our five year old plants are 2′ tall x 4′ wide. The gold color only shows with a bit of sun.
We recently visited conifer collector Bruce Appeldoorn at his nursery in the tiny town of Bostic, west of Charlotte, NC. Not only are the gardens amazing, but Bruce has transitioned from his career in landscape design/installation, to an amazing dwarf conifer nursery. He now sits atop the throne, having what is almost certainly the top conifer nursery in the Southeast US. Most everything is propagated here from either cuttings or grafting. He is part of a small contingent of regional broom hunters, who seek out and graft dwarf witches broom mutations from area pine trees. You can find out more about how to visit or order here.
We find aucubas an invaluable evergreen shrub for dry shade, and one of our favorites is looking rather nice this week. Aucuba japonica ‘Ogon-no-tsuki’ is also one of the slowest growers due to the large amount of gold in the leaf center. It is our hope to perhaps finally have enough to share in the next couple of years.
Sometimes we’re all in need of inspiration, and this spring, ours came from its namesake, Magnolia ‘Inspiration’. This stunning evergreen hybrid between Magnolia doltsopa and Magnolia laevifolia was developed by our old hosta friend, Barry Sligh of New Zealand, who sadly passed away in 2019. Our amazing seven-year old specimen is now 10′ tall x 10′ wide and as you can see if absolutely loaded with deliciously fragrant flowers. Pat McCracken of Garden Treasures Nursery tells me that he produced it for a while, but stopped because it grew too fast in containers. I agree with his assessment that it is the proverbial ugly duckling when young, but it sure makes a heckuva swan when it ages.
Flowering this week is our selection of Magnolia floribunda ‘Bridal Bouquet’. When we visited Yunnan, China in 1996, we were able to return with three seed of Magnolia floribunda, a species which seemed completely absent from American horticulture. The resulting seedlings were planted into the garden, where two promptly died during the first winter. Thankfully, one survived and is still thriving today 25 years later.
Magnolia floribunda ‘Bridal Bouquet’ forms an upright, somewhat open evergreen that sometimes starts flowering as early as mid-January. This year, thanks to our consistent cold, it waited until early March to start its floral show. The flowers have a distinctive and fascinating fragrance that we find unique among our magnolia collection. We have shared cuttings with several woody plant nurseries and donated plants to a few rare plant auctions in the hopes of getting this more widely cultivated.
We’re not sure why this sweet box is confused, but we love it nevertheless. Flowering now at JLBG with an insane fragrance emitted by the tiny white flowers. Here is our eight-year old evergreen clump in flower now.
