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.
There aren’t a huge number of Siberian native plants that thrive in our heat and humidity, but one that has been outstanding for us is Angelica dahurica. For those, who have traveled the world, the specific epithet “dahurica” means, from Davuria (Dahuria), a region of south-east Siberia and north-east Mongolia.
Angelica dahurica is a widely-cultivated, short-lived perennial herb that forms a stunning 6′ to 8′ tall hunk with dark purple stalks, and topped for us in June with giant Queen Anne’s Lace flowers, that’s a haven for a wide range of pollinators. The clump goes to sleep for the summer, re-emerging in fall, and remaining evergreen through the winter.
The roots of Angelica dahurica (Du Huo/Bai Zhi) have been used medicinally since 400 B.C. to cure head and body aches, blood toxicities, as a laxative/purgative, sedative, a remedy for swollen gums and toothaches, and as a topical anti-fungal cream…and the seeds are used as a culinary liqueur flavoring.
We offered these through Plant Delights for several years, but sales were miserable. So, we gave most away to staff and planted the rest in the garden, where we’re enjoying them. When are going to get folks to realize that height is what makes a garden design interesting?
We were delighted to find a flower on our Arisarum simorrhinum in early February, tucked in a the base of a dwarf Chamaecyparis (false cypress). This little-grown Mediterranean native, dryland aroid is first cousin to the better known mouse plant, Arisarum proboscideum. This baby has been in the ground for 20 years, so slow is the operative word.
