There is nothing you can do about the physical damage to the flowers. The new buds should be fine because they were closed when they were rained on.

Once the flowers fade in a few days time that's it for this year. The foliage will die down in late summer/fall, you cut it off and there will be nothing to see all winter. You can either leave them in the pot or plant them out in the garden. If you leave them in the pot you can feed them as long as the leaves are green.

These are lilies. They grow from bulbs and they bloom only once a year then die down. They are not houseplants although they are sometimes brought indoors temporarily while in flower.

where are you... big city name ...

once the flowering is over.. you can maintain the pot .. harvest and dry the bulbs.. and plant them in the ground in fall.. so they will bloom next year.. depending where you live ... [once the flowers are over.. the leaves wills start storing energy into the bulbs for next years emergence ....]

these are not houseplants .. and you will be hard pressed to try to keep them as such ... winter dormancy and storage would be the hardest part ...

as flora said.. the plant is fine.. its just damage to the tender flower tissue .... and there is nothing to do about it ...

Thank you all! I am in the process of buying a house which is why I want to work on my plant care. These lilies will eventually be planted in my new garden. Would I still be able to plant them in the garden at the beginning of next month or do I need to wait until a certain time to move them? Thank you all for helping me feel better about this disaster!

No, you can leave them in the container until it is time to plant in your new place. Enjoy the flowers as long as they last indoors, but once they are finished, take the container outside and keep it outside. Make sure it gets water as necessary....just enough to keep the soil moist.

I will do that! Thank you

Very pretty! Asiatic lilies are some of the most reliable and easiest plants to have in the garden, and long lived as well (I have a clump that’s come back for at least a decade). They only bloom for a week or two but the foliage looks good for most of the season.

That must be why my mom got them for me. I have never been able to keep a plant alive very long, but I am hopeful!
