I'm trying the verbena for the first time this year and so far I've found them a bit a tricky, I've chilled them, not chilled them, put them inside and out but no luck.
Don't let that put you off though, others have had better success with them than me. If I don't get anything soon, I will start again with some new seeds, they are lovely plants and I want some
I would have a quick look on the commercial sites like suttons or fothergills and see what they advise. Sweet peas I would just sow them into to some good compost. Might be worth sowing them in slightly deeper pots as they do grow deep root systems.
