Spiranthes romanzoffiana is the most widespread Spiranthes to be found in<br />
<strong>north</strong>ern North America. Starting to flower in midsummer in the far<br />
<strong>north</strong> it continues flowering until l<strong>at</strong>e August further south. <strong>The</strong> almondscented<br />
flowers and arching hood are distinctive among our eastern<br />
Spiranthes<br />
and could<br />
not possibly be mistaken for<br />
any other species. In a few<br />
areas it may hybridize with<br />
Spiranthes lacera var. lacera<br />
to produce Spiranthes<br />

Climbing down a<br />
mountainside after a<br />
bre<strong>at</strong>htaking ride in a tbar<br />
up the<br />
mountain<br />
might be<br />
foolish. Of<br />
course<br />
finding a<br />
new site<br />
for the<br />
Spiranthes<br />
made it<br />
worth it.
