Love those Joanne. I grow both. Been having problems getting my sweet peas to germinate the last 2 springs. I'm going to try sowing them in the milk jugs mid-spring , see if that helps. I use to have beautiful sweet peas.
I grew Lathyrus belinensis last year got one from 12 seeds from T&M. Not one picture. I'm going to see if he is still alive. Very small blossoms but a gret smell when you get close.
Mini marine heliotrope.
These are from cuttings. A hanging white heliotrope, smells beter than the mini.
