Rheum alexandrae - ​Not for the provincial palette is this curious, eye-popping ornamental perennial, Alexander's Rhubarb, forming magnificent, broad 45 degree yellow downward-angled overlapping bracts on erect stems all up and down the flowering stem. They are creamy yellow and curious. The actual flowers are insignificant. The event can last three months. These form an upright narrow cone from base to pointy top. It takes time for this to occur, years. But the habit is an amazing sight providing a most unusual bold texture in mid to late spring. When seen on rocky sloping terrain in their native habitat the sight is haunting, memorably so. A grouping in a naturalistic garden would be memorable also. There are varying reports of hardiness with some claiming it to be so into USDA zone 3... I'm not blankly accepting that as fact. Perhaps zone (4?)5 to 7. Some claim 6 to 8 which may, indeed, be closer to the truth. We have not experimented with this fine plant interred in our gardens as of yet so based upon what we have shared know your zone and wax conservatively! We're guessing USDA zone (5)6 to 8 with perhaps a partly shaded siting in zone 8. Placement in full sun planted in moist, fertile conditions is mandatory. Pot grown division.
