Laurie pointed that out to me when the hour changed. Haven't had time to investigate yet.
Are you OK growing the upright varieties? e.g. Crystal Palace?
My favourite is Lobelia erinus 'Mrs Clibran' and I see it has the prestigious AGM
http://apps.rhs.org.uk/plantselector/plant?plantid=3400That photo makes them look mauve, which they most certainly are not. They are the best blue and that white eye makes them really exceptional. Ive sown what looks like a close alternative this year - Sapphire and a couple of trays of Crystal Palace..
They are very easy, but I sow in March so I don't have to worry about frost. Mine are beginning to germinate this week.
In my first attempts years ago I tried growing them earlier. I had bottom heat in a seed bed in the greenhouse. Because I had to keep them in the heated seed bed environment to protect from frost they grew lanky and weak.
Then I read that they do best when given heat to germinate, then grow them on cool. So, as soon as germinated, out they go onto the top of the staging, uncovered, and that works for me. They come up in abundance.
I find String of Pearls are the most difficult. Poor germination, but they grow on OK when sown late.
I dont sow them any more.
