Verbena Rigida - overwinter.
I have now read in two different places that you can overwinter Verbena
Rigida turbers treating them the same way as Dahlias. Is this true? and how come my own young V Rigida "polaris" has a stem and small roots at the bottom, but no tuber? |

Verbena Rigida - overwinter.
I have now read in two different places that you can overwinter Verbena
Rigida tubers treating them the same way as Dahlias. Is this true? I've just treated them as a hardy perennial that dies right back in winter and gets no protection. Winters here are very wet but quite mild (coldest garden temp in three years was one night at -4). I think vr must be tougher than dahlias, which don't survive here if left in the wet soil over winter. If you have much colder winters than that, you might get away with just mulching the soil surface. Thanks Janet, I know they are borderline hardy, but the comments about the wet are encouraging. Verbena Bonariensis is also supposed to be borderline hardy - but has done well here in North Yorkshire for the last three years. They seed very easily, but if you have more than one variety of Verbena, you do not know what the seedlings are. And there are too many of them to nurse the all. |

We have Verbena rigida in various part of the garden here and it over-winters well. I love it! Like V. bonariensis, it also seeds itself all over the place and one of our neighbours has it popping up through cracks in the paving in all sorts of odd areas of her garden. If you live in a very cold area with hard frosts, it might be a problem but worth an experiment, perhaps? -- Sacha www.hillhousenursery.co.uk South Devon ) |
