I've had good results with successional sowings of lettuce, to ensure
that the crop doesn't harvest all at once. However, not much luck with
brassicas, dwarf beans, parsnip and swede.

Buying 2 or 3 varieties of say, cauliflower, to extend the harvest
season, isn't an option. Does anyone know of an online supplier, who
will provide a packet of mixed varieties. The local DIY store stocks
mixed lettuce, but precious little

If you need all year round brassicas you may well have to buy 2 or 3
varieties of each, with the exception of brussels sprouts as they are I
think a late cropping veg(Sept-March) if they don't get frozen and turn
rotten as mine have this year.
Parsnip and swede, carrotts for that matter can be sown all at once and dig
them up as needed.

If your concern is expense of buying all these different packets of seed,
don't worry they keep for years, despite the use by date. *

Hope this helps and good luck to you.

Buy them from Aldi or Lidl and they wont cost you all that much,
Most veg have different sowing dates so mixed packets would be no real
use.
