Datura wrightii is cold hardy in 5b and D. stramonium tends to self sow and can grow as an annual in that zone.
I don't know how resistant to all animals they are, but Delosperma species seem to be left alone by a lot of animals and can have gorgeous colorful blooms in container from late spring to late fall. I think they are worth a shot and they grow well with other taller plants in containers in mixed plantings.
