I sowed this pretty annual in pots but they got straggly and leggy as I didn't pot them on or pinch them out at the right time. However they are flowering profusely n spite of my neglect and I was puszzling how to support them when I remembered some white painted twigs from Christmas. Just tje thing.
These are Schizanthus x wisetonensis Dr Badger's Mix from Chiltern Seeds.
