Tomato seeds will survive a sewerage plant process!
Verbena Bonariensis in my garden, does not get re-cycled through compost, but simply self seeds with or without help from birds and insects. It means that come September I will dig out all this year's little seedlings and overwinter them in the g/h.
If it is a warmish winter, like last year, then this year's plants will keep going, but normally I lose them in a cold winter. So next spring the over-wintered seedlings will get planted out.
