Do these lilies have virus?
Could someone please help me decide whether the pictured lilies have virus or not?
The first two pictures feature the same Stargazer lily. At the time when the stem was short, the leaves were of nice dark green color. But within the last couple of weeks the new growth was getting lighter and lighter, so now I'm concerned... I have taken both the picture of the tip and the stem because except for the light color, the plant itself looks strong. I wonder whether it will stay strong though...
On the last picture I have Gold Stargazer, which was put into the ground just 1.5 weeks ago. Its leaves now have long yellowish bands.
Is this a clear indication of a virus, or could it be because of the hot weather (every day last week we had temperatures like 85-90F, but lilies were regularly watered in the mornings).
