Tall acquatic plant with blue/purple flowers
SOLVED: Tall acquatic plant with blue/purple flowers ID, Please
I have one in my pond, last year the bloom scape was over 6 feet tall!. Looks like they grow better in warmer climate. I didn't know they got that big, the leaves on your images are HUGE!
Yes, some parts of NZ seem to produce almost sub-tropical-like plants with lovely big leaves!!
