I first saw this some years ago at Kew and was very impressed with the very fine delicate foliage, turning golden in autumn. Further research told me that it doesn't do very well in the UK because it's not warm enough here in summer. Happily I'm here to tell you that isn't the case.
Arguably the best of the Amsonias – a relatively small species (to 18ins high) with very fine fresh green foliage which can colour up amazingly in the autumn in shades of gold, russet and maroon. The soft mauve flowers are just a very pleasant bonus.
Easy to grow anywhere in sun but does best on a sunny well-drained soil.
