Hold on to your hats, folks. This one’s a doosie! In 2003, an expedition to the (tongue-twisting) Namchabarwa canyon* in Tibet discovered this rarest jewel of a “jewelweed” – an ultramarine-blue, flowered Impatiens. It was found in a very limited & remote location, but its scarcity doesn’t at all impede its cultivation - not only is this plant hardy (how hardy is as yet untested, so let us know) but it reseeds, making it a triple whammy of a plant – super rare, totally gorgeous, & completely garden worthy. The plants are compactly growing to about 2’ x 2’ & very floriferous & the 1.5” flowers themselves are breathtaking in color & in form. The color seems to change with temperature & exposure – sometimes it’s REALLY TRULY BLUE & other times it’s a deep purple, but it’s always exquisite. Truly a plant to treasure, if you can get your hands on one! *A canyon that’s not only the deepest canyon in the world - twice as deep as the Grand Canyon - but is also an area that’s been studied only since 1994. Can you say WOW? Note: Generally, species Impatiens prefer cool Summer climates with little frost, and suffer in areas with too much heat and humidity!
Stunning new impatiens from one remote location in Tibet's Tsango Gorge, in moist, shady clearings with ample summer rainfall. More annual than perennial, germinating in early spring and producing dazzling, blue flowers from late spring to early summer - even through the first light frost. Can be brought through winter as cuttings but does reseed in well watered garden areas. Perennial in USDA zone 10; reseeds in colder zones.
