Jim, That would be late June (var. citrinum) around the time regale usually flowers. Henryi is always my second lily to flower after the dauricum types. I can second that observation that in some years my rosthornii pods have barely reached maturity before the first frost. Even if all the seeds are not mature I can usually get enough from the 20 or so stems.

" Aaron, I know you're south of here, but June seems very early for Lilium henryi. Here in USDA zone 7 Maryland, just north of Washington, D.C., it blooms in mid-July. Griffiths, writing about a century ago, noted that even plants growing in northern Virginia often did not ripen properly outside before freezes; he suggested cutting the stems and maturing them indoors in water.
