One of my standard delenatii is a smaller plant, atleast with narrower leaves. It was sold by saing 'Big', which I understood with bigger flower/flowers. I can't say anything yet, because, it had flowered already, when I got it. Then I don't know why, but alarmingly the flowered shoot started first with just one leaf turned yellow. Then suddenly the hole shoot turned brown. It's usually not a good sign if the plant wilts so fast, but the new shoot was good, no sign of any stress, so even it was December (I have never before replanted anything in the darkest time of the year.) I replanted it. All the roots were healthy, not even one had died. At the same time I saw, that it had started to make two new shoots more. Now two months later, it's doing just fine and continues to grow.
Sorry, it got a bit long story now.
