Does Diascia personata overwinter well?

  My diascias survived for several years in a large container with no protection but last winter did for them. I've replaced them but haven't found a red one yet. I'm keeping an eye out.

  In London. Keen but lazy.

  My diascia personata has not returned this year. It’s survived previous winters, but I think this one has been too cold and wet. Great tall upright plants that flower for ages, as you say. I would like to replace mine, but it’s not something readily available at the garden centre.

  I've been lucky then, my diascias seem to have survived. I overwintered some in the un heated greenhouse but forgot about others in a trough on the terrace which also survived to my surprise.

  @Lizzie27 Is that diascia personata? Or the low growing one sold as an annual? About 5ft in this photo.

  Diascia Personata should be a able to take on the average London winter, however this winter, it's been pretty cold consistently. The bigger issue is the constant wet. In a container, it's easier to control, but if you plant into the ground, you have to make sure the ground is well prepared with plenty of drainage to help it survive the wet over the winter. In my opinion, it's well worth trying again.

  Golly, @pitter-patter, I didn't know they grew that big! I think mine are probably the annual ones in that case - unless of course I've got them mixed up with nemesia.
