Here are few images of our Solomon’s Seal (polygonatum) going to sleep in the garden. We think they are fascinating even as they approach dormancy. The top image is Polyongatum falcatum showing the amazing fruit set contrasting with the aging foliage.

The next image is Polygonatum odoratum, which probably has the best golden fall color of any species we’ve observed. At bottom is Polygonatum involucratum showing the transformation of the involucres (the pouches that hold the flower), and they age to tan, prior to the leaves changing colors. Solomon’s seal are cold hardy from zones 4 to 9.
Solomon’s Seals comprise several genera of woody perennials, but the common name is most commonly associated with the genus, Polygonatum in the Asparagus family. It seems hard to imagine, but the Asparagus family now includes many popular garden plants including its namesake Asaparagus, but also hosta, agave, liriope, ruscus, and yucca.
The genus Polygonatum is native through much of the world, although the center of distribution is in Asia. We’ve been collecting these amazing woodland perennials for years, and now have a collection of over 380 different taxa. Here are a few from this week in the garden.
Polygonatum mengtzense is a dwarf, rarely cultivated species from North Vietnam.

The dwarf, glossy-leaf Chinese Polygonatum nodosum just oozes elegance.

When you run out of species to grow, you start creating hybrids. This is our new selection of a cross of the giant Polygonatum martinii and the more compact, Polygonatum falcatum. We’ve named this clone Polygonatum x marcatum ‘Winsome Wonder’
Polygantum x marcatum ‘Wisome Wonder’
Polygonatum odoratum ‘Chanticleer’ is a superb, large-leaf form of the Asian Polygonatum odoratum that I spied at Chanticleer Gardens, and they kindly shared in 2006. Hopefully, we’ll finally have enough to share next year.

Polygonatum odoratum ‘Angel Wings’ (aka: ‘Carlisle) is a superb form of Polygonatum odoratum from Massachusetts plantsman, Roy Herold. This gem grows in both half day sun as well as shade.
This is the best fruit set we’ve ever seen on the Chinese Disporum longistylum ‘Green Giant’. We love this semi-evergreen Solomon’s Seal, that was collected and introduced years earlier by our friend, plant explorer Dan Hinkley. On the West Coast, this reaches 7′ tall, but here in the hot, humid southeast, we’ve never had ours exceed 3′ tall. Nevertheless, we’ll enjoy our great crop of cobalt blue fruit this winter.
The late plantsman Alan Galloway was a prolific plant collector in Southeastern Asia, and one of the plants that has surprised us with its winter hardiness is the giant evergreen Solomon’s Seal, Disporopsis longifolia. In the wild, Alan and I encountered this throughout Thailand and Vietnam, but our tallest clone is one which Alan collected in Laos, and we christened Disporopsis longifolia ‘Alan’s Laosy Giant’. Our clump, which has been in the garden since 2007 has topped 5′ in height and is in full flower this week. Sadly, it has yet to produce a single offset.
Throughout the year Plant Delights is continually adding new plants to our website. We have just added over 40 new plants this past weekend. You can check out all the new additions by clicking here.
Some of the exciting new additions are Disporopsis ‘Zebra Stripes’, an evergreen variegated Solomon’s Seal which forms a nice 22″ tall clump by spreading underground rhizomes.

Aucuba japonica ‘Fujikawa’
Aucuba japonica ‘Fujikawa’ is compact female form and will form a 4′ specimen in 5-7 years. The narrow leaf gives a fine texture. If there is a male cultivar nearby, ‘Fujikawa’ will produce bright red berries in the winter which really stand out against the dark green foliage.
