Gardeners' Notes:

Positive stevenova On Apr 13, 2004, stevenova from Newcastle
United Kingdom (Zone 8a) wrote:

A beautiful and hardy orchid with relatively tall spikes of heavily scented flowers that spiral up the scape in August and September. Probably extinct in the wild, this form is more vigorous than most in the genus and is easy to propagate from vigorous creeping rhizomes.
It will become more popular as a garden plant when it becomes better known.
