Connoisseur Plants

Connoisseur Plants are rare, new plants, or hard-to-find old favorites. These wonderful plants are being offered to our upper level members, Collector (formerly Sponsor) level and higher.

Please note that several plants are available in very limited quantities. For some plants, we don't know the full range of hardiness, only how it has behaved at the JC Raulston Arboretum. Sometimes, we cannot find any information in our references on a particular taxon. This does not mean that the plant doesn't exist, perhaps just that we are staying one step ahead of published information. One of the purposes of the Arboretum is to test new plants for suitability to the southeastern United States. By growing some of these "new-to-us" plants in your own garden, you can be a part of this evaluation process. Feedback from you is invaluable!

Happy choosing, and thank you for your continued and invaluable support of the JC Raulston Arboretum.

To submit your selections, please use the form link in the e-mail you received on February 21, 2024 from Kathryn Wall. If you need assistance, please e-mail Kathryn at kbwall@ncsu.edu or call (919) 513-7004 Selections should be placed no later than end of day March 3, 2024.

Note: The distribution year listed below is the year the plants were awarded. Members request them early the following year. And they're picked up or delivered shortly thereafter.

Aloe ecklonis
grass aloe

This species of South African grass aloe forms an attractive rosette of succulent leaves with tiny, white-toothed margins.

Aster ageratoides var. scaberulus
mountain aster

This Asian woodland aster makes a spreading clump of sandpaper-textured foliage topped in fall by cheery white daisies. It is quite easy to grow and seems happiest in a bit of shade. Once established, it will tolerate and even thrive in dry shade with just an occasional watering to keep it going during the driest stretches of the year.

  • plant in part shade
  • hardy
  • white flowers in late summer-fall

It will also continue to produce its peachy-yellow 10" trumpet flowers all summer long without taking a break. Most angel's trumpets flower, then stop and grow before flowering again while this hybrid grows and flowers at the same time. The fragrance of the large trumpets will enchant you on a summer evening.

Compact Angel's Fishing Rod

This is among the smallest of the dieramas, growing to only 2' from a grass-like clump. The wiry flower stems bear pendant flowers of bright pink which tremble in the breeze.

Helwingia japonica
Japanese helwingia

Rare in nature, this attractive and unusual deciduous shrub has been growing in the JCRA Lath House since 2012. In spring, look closely at the tops of its broad leaves, where you will find its tiny green flowers. Fruit production is a little bit tricky since both male and female plants must be grown together. Expect it to reach 5’ tall by 5’ wide when grown in a site with light shade; moist, yet well-drained, humus-rich soil. This Connoisseur Plant is derived from cuttings taken from the plant growing in the JCRA Lath House (MWT09-438) which was collected in 2009 in Taiwan by Mark Weathington.

  • plant in sun to part shade

Hydrangea aff. chinensis
Chinese hydrangea

This is a taxonomically perplexing species and there is still very little information available about this hydrangea. Our friends at Far Reaches Farm (Port Townsend, Washington) have been growing one they obtained from Quarryhill Botanic Gardens and say, “In a very few short years, it has insinuated itself into the short list of plants that we would run into a burning greenhouse to grab.” They report it flowers young and has green elliptical leaves that pair nicely with its large corymbs of white fertile flowers, bordered by pure white sterile florets. These plants were propagated from seeds collected in Taiwan in 2014 (MWT14-1029) by Mark Weathington.

  • deciduous shrub to 3'
  • plant in shade
  • white flowers in summer

Illicium floridanum 'Pink Frost'
variegated Florida anise

Anise are among the most deer resistant of evergreen shrubs making this bright foliaged plant a must grow.

Burgundy spring flowers are showy against the foliage. Available for pickup only.

Magnolia compressa
Taiwan magnolia

We collected this plant with the help of the Taiwan Forestry Research Institute who called it M. compressa var. lanyuense, a dubious name at best. It will make a narrow, evergreen tree with small white flowers stained purple at the base. Plant it in a sheltered spot as it will likely be somewhat tender.

  • evergreen tree to 40'
  • plant in sun to part shade
  • semi-hardy tender
  • white flowers in late spring
Magnolia compressa

Magnolia dawsoniana
magnolia

This choice magnolia is on the IUCN red list as an endangered plant in the wild. It was first brought into cultivation by the great plantsman, Ernest "Chinese" Wilson, in 1908 after discovering it in Sichuan, China. It makes a lovely, mid-sized deciduous tree bearing large (to 10") pink flowers. It is truly an aristocrat of the plant world.

  • plant in sun to part shade
  • pink flowers in spring

Rhododendron
rhododendron

This rhody was collected high on Taipingshan in Taiwan where it formed a large shrub with glossy, pointed foliage. The seed heads were quite large, over 1" long so hopefully the flowers will be large as well. This may be Rhododendron morii which would mean it would have pale pink flowers.

  • evergreen shrub to 6'
  • plant in sun to part shade
  • hardy semi-hardy
  • in spring

Salvia hierosolymitana
Jerusalem salvia

This lovely herbaceous perennial is native to Cyprus, Israel, Jordan, Lebanon, Syria, and the West Bank. Jerusalem salvia forms a basal rosette of large, dark green leaves to 18” wide. Wine red to pink flowers with a light fragrance are produced on 2’ stems. It flowers on and off throughout the growing season and seems especially generous in spring and fall. Use it as a ground cover or border plant in a sunny, well-drained location in your garden. These plants were grown from seed the JCRA obtained through 2015 index seminum from Jerusalem Botanical Gardens, Israel.

  • plant in sun
  • wine red to pink flowers in spring-fall

It looks best when growing in part shade among other perennials.

In late spring to early summer, they are covered with long-lasting, small, white flowers. We have not grown this before and invite you to trial this one along with us.
