What does everyone think about the discoloration on these leaves?

Thanks,

Matt,
I don't have an answer. But, on a hunch, have these been exposed to a light frost?

Only last fall, just before I brought them into the house.

Were these leaves already emerging when they were exposed to the cold? And have you had this discoloration since then (or nearly since then)?

All these leaves are new this year. I had all the bulbs in the basement all winter - brought them up about a month ago. I don't remember seeing this in the past.

This is what virused leaves look like:

The virus doesn't really show up on new leaves especially when grown in the house. I'd keep this bulb away from your others just in case though but I wouldn't panic quite yet.
When you put it outside in the hot summer sun the symptoms will reveal themselves for sure if this is a virused bulb.

Oh, then disregard the frost hypothesis.

Ahhhh! Horror of horrors...I was afraid of that. How far from each other should they be in the house?

A virused plant shouldn't be touching any other plants in fact if you can isolate it in another room all the better. If you have a virused plant don't touch it and then touch another plant you must wash your hands. When you break off a stem or remove dried leaves you must destroy them and certainly don't touch any other plant with plant juices on your hand, even the computer that you may go back to later and inadvertently spread the virus. Don't use the pollen from a diseased plant on any other plant that is healthy. The general consensus is that seeds grown on a virused plant are healthy. I can attest to that so far but there might be exceptions to every rule. Hopefully you haven't any bugs in your house as that's the best way to spread the virus through chewing insects that bite the virused plant and then bite others amaryllis. If you do choose to pollinate a virused bulb make sure that whatever you dab the pollen on with doesn't go back into your vial of pollen or you could contaminate the rest of that particular pollen. I wouldn't knowingly use a pot over that has held a virused bulb unless it has been soaking in a bleach solution for 15 minutes or so.

Bottom line is if you feel sure you have a virused plant and it isn't something that you can't replace then get rid of it and buy a new one. No need to take chances.

Now, I'm not saying your plant is virused that decision is for you to make. And as I said before I've never seen new leaves on any virused plant show the mottling until the plant has been out in the sun.

Also, papilio is said to be virus resistant. You can read loads of material on this forum on this virus issue which I would advise you to do. We've had some pretty hot-under- the-collar discussions about this!

Let us know what you plan to do.

Thanks Donna - I guess I'll just wait and see.

They have had some direct sun light last week.

Matt, It has to be direct hot summer sun with the plant outside for a few months. Stress is what makes the symptoms appear, hot blazing sun and drying out from time to time. Winter sun through a window wouldn't do it in my opinion. Dappled sun in the summer might not do it either.
