How many Heuchera should I plant in a 50cm pot?

This question was asked by

Hi Both,
I recently followed your Twitter posts and am getting hooked on heucharas. I work as a part time gardener and am noticing more and more different coloured ones in my work.
Q: I have a terracotta pot, at 50cm wide and want to grow a selection on heuchara. Should I simply buy plant or 3 different coloured ones. I’m attracted to a variety of colours.

Hi Coral
Thanks for following us on twitter
Pleased your enjoying your Heucheras
In that sized pot I would recommend to start with put 3 then if after 3 years they grow bigger just split the 3 up and replant where you like 😀
Hope that helps
Kind regards vicky
