The most valuable ornamental species tested by the writer is Celastrus punctata, from the Amur valley in Asia. It is far more rapid in growth than our native bittersweet, its foliage is darker green, and as yet it seems to be free from insects and attacks of fungi. The bright-colored fruit popularly known as "wax-work" hangs on late into winter.

The native species, Celastrus scandens, is also valuable for porches if given woven-wire trellis to encourage upward growth. It is also specially valuable for covering arbors, rock-work, wire fences, etc.
