Verbena tenera Sissinghust Pink

"Perennial (grown as an annual)" - having taken cuttings/transferred to pots to overwinter it in the greenhouse for years, left it out last winter (down to -4C on occasions) and it's never done better.  So I won't be faffing around again, wherupon they will probably promptly die.  I'm fairly sure that the combination with China Town was not in the mind of the person from whom I bought them, who is famed for their colour combinations.
