lol so the flower and the grass like plant are not connected...
I just moved the plants to this area, the flowers just started showing up.
I do recall putting some rain lilies in last year. Thought they all had died, never saw a bloom, there are no leaves associated with the flower, just a flower sticking up out of the ground. We have had a lot of rain.
Oh, I think the grass-like blades are the foliage of the rain lily. I don't have this particular one, I grow Z. citrina, a smaller yellow one in pots, and the flower scapes are separate from the foliage.
The striped grass like plant survived our winter here, zone 6ish. We got down to -6 briefly. So I don't think the plant is associated with the flower. Maybe my rain lilies just want to flower and not grow leaves. It says they are zone 8
