Not grown these before, so my first time this year (lockdown seed frenzy!) I've read that these are really easy to grow (in fact, I remember my late grandmother telling me that her father used to grow these to sell as cut flowers in the village they lived in back in the early 1900s). I threw some seeds (2 whole packets - giant green ones, and single mixed) down in a couple of empty spaces, one south facing bed, one west facing) and I've only got 3 plants come up, in the south facing bed. One flower just opened, and the other 2 plants are a bit on the weedy size.
What have I done wrong? I know I haven't accidentally pulled them up whilst weeding, I watered the spaces, the seeds were bought only last year, so I am at a loss.

They are not hardy, so most people start them off with some heat, grow them on, then plant them outside after the last frosts.

"luminous"? Marigolds, petunias and geraniums are brighter. Zinnias are one of my favourite daisy type flowers. They brighten my garden and look beautiful!
No problems with slugs and zinnias as you can see in the photo. Slugs prefer my hostas. Maybe plant some hostas in the garden to keep slugs away from flowers.
