Found this great post on Michelle Hamer's blog, From Seed to Table, on growing and propagating capers - great to have some firsthand experience of growing these amazing plants. I've been looking for some good info on propagating capers and this is the best so far.
We had our first caper berry a couple of months ago - a lovely plump specimen! The bush itself is probably some 12 months old and doing okay so far, in a pot. I'd like to try and propagate some more plants from seed, so when it comes to our new landscaping, we can plant out some caper bushes as part of a rockery.
I'd love to know of anyone (especially Perth locals) who has given capers a go, maybe as a rockery plant, with some success!
If you're new to capers like I am, you might find this site useful too.
