When I divided a lot of clumps of SI two years ago, I placed a transplant clump where I thought it would/might not get enough sun, but it has bloomed as well as others with more sun (early in the year it is fairly sunny there, but as the season goes on that area is more shady). Is that it blooms well the real determinant of it getting enough sun when it needs it? (I want to move more SI to a similar area). It is more floppy than others with more sun and where the leaves/stalks are firmer/ more upright than this one. Thanks for any info.
