Can you post a picture? Blanket Flower should do fine in most sunny conditions. Did the container dry out? Did the plants get watered during peak sun hours? Sometimes the drops of water on the leaves can cause sun scald. That is why early morning watering is best, before the sun is strong.

The drops of water causing sunburn thing is largely a myth. Only under some very specific conditions is it a remote possibility.

Here is a link that might be useful: drops of water

These are not good as container plants. The watering is almost impossible to get right. They need to be planted ASAP.

Kevin,
Thanks for that link! I'm very relieved to know that I can water whenever I have time without worrying that I'll over stress my plants. I worried the most about fragile seedlings that were just planted out. They need water ASAP, but I can't plant everything before 11 am on a Saturday morning.LOL. Thanks again.

nothing.. in a pot.. should be in full sun at 90 degrees ... or ever really ....

it has nothing to do with the plant leave tolerance ...

it has to do with how hot the pot got.. and how you cooked its roots ... interfering with water management ....

not only does the heat make the plant transpire heavily ... but it interfered with the roots ability to process enough water to offset it all ... and depending on pot size.. perhaps dried out ....

all my pots are kept in very bright shade... here in MI.. regardless of the plants sun tolerance ... and its the same reason no nursery worth its salt.. leaves potted plants in full sun ... unless there are hundreds of them stacked close together... to shield the pots themselves from sun ... observe next time you are plant shopping.. you are rarely standing in blinding sun.. looking at pots ... shade cloth.. lathe house.. greenhouses.. etc ... [bigboxstore is not a nursery .. lol .. they do have them out on the blacktop often .. and most of us know what they look like after a few weeks]

make any sense??
