I got this plant back on March 8th 2018, it has never really been a strong plant here. It has had slow increase every year, and is still a very small clump. I bought it because it is a sculpted relief form. I am finding that often sculpted relief daylilies are not the strongest, or most prolific or fasting multiplying plants. It has a low bud count, a low branch count and a short bloom period for me.
Edited to add a couple of photos:
These are just two examples of the sculpted relief blooms produced by 'Bas Relief'.They illustrate why it is often so hard to identify a plant just by the blooms alone. The second photo shows a lighter colored midrib that I don't recall seeing on many of the blooms. To me the second bloom also appears much more yellow in color also. Both are off the same plant in different years.
