There are a whole load of different colour ones, but I'd have to google them to find out where to get them. Look for Kniphofia
I've just started my tomatoes and cosmos in a propagator at home, I did my sunflowers in April last year.
If you wait until autumn they will be dead. Plant straight away as they will probably flower, throw away any that have gone soft or mouldy
I've won once, girly pink hand tools. Also won on Grow Your Own magazine, RHS Apple book. Last year I won the prize draw for the Insiders questionnaires, £250 Amazon vouchers
You should be able to see some roots at the bottom of the pot, unless it has just been potted on to sell
Iris reticulata usually come out before crocus
Definitely blackcurrants, cut out some of the thickest oldest stems down to the ground. Leave the younger growth

No they are not a marketing trick, they grow huge in their second year, pretty tall in their first year too
