At Kew J. caroliniana has been in continuous cultivation 
for some ten years past, growing well and flowering freely 
every year in the Rock Garden. A native of swampy 
places it shows, even under cultivation, a predilection for 
swampy conditions, and if these be provided it sets seeds 
freely. In 1908 a fresh supply of seeds was presented to 
Kew by the Missouri Botanic Gardens, and from one of the 
plants so obtained has been derived the material for our 
plate.
