Now, funny you should raise that topic! My wife asked yesterday why I dont grow any Cornflower any more!
They did very well with me, sowing in open ground.
The answer was - I was so behind (due to computer work) that I didnt have time to clear a nice patch to sow seed in time.
I used to grow a lot from seed, sown outdoors. Is it easier than the greenhouse? Depends on your garden I suppose. I used to mark a circle with sticks, and sow the seed inside the ring. The fun think about growing new things from seed is you havent a clue what the new seedlings look like. So, until I got to know my weeds better (and thats a serious statement) I used to compare what came up inside the circle with what grew outside.
That worked well, bar one - Myosotis Sylvatica.
What came up inside was exactly the same as outside. I thought the seed had failed.
Nope, my garden was already overgrown with Myosotis Sylvatica - best known as Forget-me-not (you knew that, didnt you) - self seeded everywhere. Once you have them, they are there for life. They are not a problem - they are easily removed, and you can leave well sited ones to grow and flower in-situ.
Another trick that worked well to suppress weedlings in my seedlings - I covered the planting circle with about 1in of peat or old compost.
Lobelia?
I love the stuff.
After many failures, I found they grow easiest from a late spring sowing. Early sowings had to be given protection, and they always ended up really spindly, collapsed and died. They need heat to germinate, then colder conditions to grow on. By sowing late, all the difficulties are overcome. I usually sow a large tray or two, keep them covered with a sheet of glass until germinated - then remove the glass and grow on.
Pricking them out. Singly? Well, I have to confess I read the same book and tried that. As Eric agrees, its Ridiculous.
I wait until the tray is full of foliage, and dig out clumps of the seedlings, and put them in 3in pots.
I use the upright varieties outdoors to fill "holes" in the front of borders, and in containers.
The trailing ones are good for hanging baskets, but I find them harder to grow.
The best upright Ive grown is Lobelia erinus 'Mrs Clibran' from Chiltern Seeds.
