The Seals of Solomon

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’

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.

Green Giant in fruit

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.

Alan’s Laosy Giant

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.

Here are a few images of seed pods around the garden this week.

New baby tucked away in plain view

Even though we’re in the garden virtually everyday, there’s so much to see that we often miss things that are right in front of us.  Case in point…a few weeks ago, our taxonomist, Zac Hill was walking though the woodland garden and noticed that our evergreen Solomon’s Seal had been sexually frisky with another disporopsis species in a nearby clump. In the photo on the right is the daddy, Disporopsis pernyi, and on the left, the momma, Disporopsis undulata.  In the center is the baby…a hybrid between the two.

The hybrid clump was actually fairly large, so we’d missed the blessed event by several years. According to disporopsis guru, Dr. Aaron Floden of the Missouri Botanical Garden, this seems to be the first time that anyone has documented a hybrid between these two species, so we named our new baby Disporopsis ‘Opsis Attract’ and look forward to being able to share in a few years.

 

Hit gold with Solomon’s Seal

Several of the Solomon’s Seals age gracefully, but we’re usually too busy writing catalog copy to get photos. This year, we happened to catch Polygonatum infundiflorum ‘Lemon Seoul’ all lit up in its fall fines.
