When do you bring your tender perennials inside?

I was wondering when others bring their tender perennials into the greenhouse? Right now my begonias, fuscias and verbena bonariensis are still flowering outside, and my dahlias are just starting to flower(!). But I'm worried about the weather by PurplePoppy

Hemizygia (Candy kisses) Over-wintering / frost damage

I have some Hemizygia in an outdoor pot which has turned black with the recent frosts. Is the plant dead or is it just the foliage? Thanks! Tender perennial-I fear you have lost it by Lucilla Sallabank

White Aster turning red

perennial hardy Aster and a Tender Aster. If yours says for one season it is most likely the tender one. The red tinge is not unusual plants often have small variations. I am still dead heading my plants in the hope that we get a warm September. by Kitty Jingga

Winter mulching

Could anyone advise a relative beginner on mulching perennials for winter. Should the crowns of tender plants be covered or just the bases, and if so must the mulch be removed for spring? Thanks for any advice. If you're mulching in order to protect by lilly3

Rudbeckia in Planters

someone will. I thought Cherry Brandy was a tender short lived perennial, but Sarah Raven lists it as a half hardy annual. Anyway, it's usually thrown away after the frosts and re-sown under cover in early spring or bought as a plug plant. Thompson by Dave Cooper-Hughes

nicotiana mutabilis

I was given some of these late in the season and they're obviously not going to get to flowering before the frosts. Are they annuals or tender/half hardy perennials? If I dig one up and bring it into a cold greenhouse might it survive long enough by Angie 3
