2000sd547  BASE#9678:RSBG  (+5 to +10\R1\5).  Our first offering of this big-leaf species in many, many years.  This species has somewhat smaller leaves than many of its more exuberant relatives, but makes up for this with outstanding yellow or cream flowers in late spring, well past most of the other big-leaf species.  These are grown from my collection of seed at 9,800 ft. on the Yunnan/Burma border.  Very rare in cultivation.
