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.
As an avid bromeliad collector back in the 1970s, I’ve had a long fascination with members of the bromeliad family. Although, I’m long past my house plant days, I continue to test bromeliads from cold climates for their adaptability in our Zone 7b NC garden. So far, we’ve had one member of the genus Puya to survive for well over a decade, so we’re trying more. Here is our trial clump of Puya caerulea var. violacea this week, where it is thriving so far in the crevice garden. This 2.5 year old plant is just waiting for a really cold winter to see how it fares, but so far, so good.
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?
A new hybrid that just been amazing in our garden this summer is Origanum ‘Drops of Jupiter’. This Walters Garden introduction is the ultimate edimental…a cross of the gold-leaf culinary oregano, Origanum vulgare, with the flowering Origanum laevigatum. The result is an amazing flowering plant with incredibly fragrant golden foliage. Here is our plant at JLBG putting on quite a show.
Flowering this week at JLBG is the little-known, but marvelous Liriope longipedicellata ‘Grape Fizz’, thanks to the exploits of plantsman Darrell Probst. We find this tightly clumping species much more interesting than the more formal Liriope muscari or the weedy, spreading Liriope spicata, and will tolerate full sun to shade. By the way, pedicles are stalk-like structures connecting one plant part to another….in this case the flower stalk to the flowers, hence the specific epithet longipedicellata (long pedicles).
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.
Cyrtomium macrophyllum is looking particularly fabulous this year. This is a little-grown holly fern with a wide range from India to Southeastern China that can be found at elevations from 2,500-8,000′. The bold textured fronds arch outward to make a 2′ tall x 2′ wide clump that is semi-evergreen in most winters. It seems as if we will get good spore set this year, which may mean another offering since the last time PDN had it to share in 2003.
Most folks think of yuccas as only sharp plants, but one that’s sharp without being sharp is our Southeast US native Yucca x recurvifolia…a naturally occurring hybrid between Yucca aloifolia and Yucca flaccida. Here is the clone Yucca x recurvifolia ‘Variegata’ in the gardens this week. Hardiness is Zone 6b/7a and south.
Over the last few years, we’ve been growing more and more aspidistra (cast iron plants) from seed in the garden. Here are a few of our more interesting seedlings. The first is from our search for a narrow-leaf selection of the common Aspidistra elatior, which has been christened A. ‘Thin Man’. The second is a streaked and spotted form that we named A. ‘Zodiac’. The third is a yet un-named seedling from Aspidistra ‘Snow Cap’. Surprisingly, the white leaf tip trait comes consistently true from seed.
