Identity unknown of August blooming lily?
Last week, my neighbor have me 6 substantial plants. I don't know the identity so I am looking for help. I know the following:
1. The bulb is a pretty substantial looking "onion" with strong roots. (amaryllis looking white inion)
2. The leaves resemble daffodil leaves.
3. A beautiful single stem pink "lily" comes up around August 20th in Zone 5.
If anyone is familiar with this flower, please help. I don't know anything about it and would like to know any care tips. Thank you all in advance for your consideration.
