This is the cultivar that made me fall in love with daylilies. I received a spindly plant in a pot as a bonus with an order of mixed perennials, and I threw it into a bed without expecting much. This was maybe 2016? Anyway, the plant took off, it bloomed, and I was in love. Since then South Seas has been nothing but an excellent performer for me. My original spindly plant has become a huge clump, which I recently divided. In its second summer, it not only bloomed profusely but rebloomed, and it has rebloomed every year since. It's got healthy, beautiful foliage, and I adore the electric coral color of the blooms, which can be seen all the way across the yard. Scapes are 30" at least.
I see that the database entry says it's susceptible to rust, but that hasn't been my experience (knock on wood).
It's still my favorite, and I would recommend it to anyone.
This picture is from last summer, before I divided that large clump.
