Polygonatum vert. "Himalayan Giant"

Jane,

Yes, Diana, Hinkley, Kelly & Sue, and others have introduced some great Chinese and NE Indian Polygonatum into cultivation. I still need to get Diana's collections.

Most of the European forms of verticillatum I have are relatively small and usually remain under 2 feet tall. They have terete spreading rhizomes and make small patches.

Most of the Polygonatum prefer their rhizomes right at or just below the soil surface. Planted too deeply can lead to rot, but can also lead to quicker rhizome branching in species that typically offset.

That seems to explain why I have two different-looking
plants under
the name Polygonatum verticillatum. One is larger than the
other in
all parts and spreads faster too. Several interesting
Polygonatum
species have shown up at nurseries and plant sales in the
Portland,
Oregon area in recent years, particularly some introduced by
Diana
Reeck of Collectors Nursery. They are a useful foliage
contrast with
other shade-tolerant plants such as hostas and ferns, and
the stems
in flower or later can be cut for elegant, long-lasting
arrangements.
Although some spread fast, they are shallow-rooted (here,
anyway) and
thus easily controlled.
