Why are the daylily leaves bleaching out at their midpoints? Is this sunburn or something else? This is So Lovely from Oakes Daylilies. In mid March it was infested with aphids and had spring blight. It recovered nicely but didn't bloom. Now it looks the way I would expect it to look in Dec(it is semi-evergreen). But I've never seen this bleaching effect before. All my daylilies ( 20 different cultivars) get overhead watering from my irrigation and are in full Florida sun after 10AM. Everything did great this summer except for So Lovely which is planted in 3 different spots. It did fine in 2011 &2012 which were abnormally dry. This summer has had average moisture. Its my favorite one, so I am very sad that it seems so unhappy.
