Impatiens namchabarwensis: Sapphire Jewelweed with Blue Crane-Like Flowers

Impatiens namchabarwensis (sapphire jewelweed) has serrated leaves the color of polished jade, while flowers are a remarkable sapphire blue. Far different from traditional flat-disk bedding impatiens, the flower shape resembles an elegant crane in flight. Grows remarkably fast, reaching almost 2 feet tall and wide. Shines in a woodland garden.

Noteworthy Characteristics

Self-sows, sometimes prolifically. Discovered in 2003 in the Namcha Barwa Canyon in Tibet.

Care

Very adaptable; survives in hot areas if grown in full shade; otherwise happy in partial shade with rich, well-drained soil and regular watering. May survive in sheltered Zone 9 if not hit by killing frost.

Propagation

Best to start with fresh seed sown in a pot with a season of stratification (damp, dark, cool). Or take cuttings and overwinter as houseplants.
