(aka: I. sp. CPC 19.4.01 #1A) This Darrell Probst collection comes from China's rich Sichuan Province. We are still uncertain about the species, but I. 'Sichuan Gold' has performed quite well in our trials. From underground stolons, I. 'Sichuan Gold' makes a nice open colony of stalks that play well with others. Slightly moist soils are best but not necessary. The 18" tall stalks are clothed with green leaves and are topped, starting in mid-June and continuing into October (NC), with 3" branched flower stalks of large yellow flowers. You can forget about trying to root cuttings of this one...dividing only. In trials it has survived -18 degrees F in Minnesota with no snow cover...amazing!
