Collect some if you like, but let it seed itself and leave it to grow where it germinates. I find it doesn't do so well sown in trays, pricked out, potted on etc. It can be done but the plants are lesser specimens
Salix caprea is a common one to turn up in gardens
Honesty is biennial, you need to let it seed in the garden for best effect, don't sow in trays. Plant out the ones from the GH after a bit of hardening off and they may flower this year.
I don't try. I know when I'm beaten
It's one of the callistemons,
Which plants are you asking about?
anything that snaps off is dead but I have had them recover from nothing left on top after a mild winter.
Where are you? they're not hardy enough for outdoors in the colder parts of the country. They don't survive the average winter for me (East Anglia)
I have seen these pruned back to a stump, yearly.
Which ones where you thinking of growing Bob?
