Datura trumpet flowers

First year I have had these flowers. Do I cut them down or just leave them? They are in the garden. How do I keep them safe in winter?

I also have lupines. Do I cut down to roots or just leave leaves on?

Look forward to your reply.

Winter care for your Datura will depend on your growing zone.
Freezing will kill the plant to the ground and if you live in zone 8 or warmer the plant will regrow in spring.
The plant does usually reseed itself and if you live in a colder climate you will likely see new plants starting in the spring.

Lupines will depend on climate and variety. Some may grow as an annual and some may be a perennial variety.
