Hi Martin,
The B.ericifolia is about 0.7m tall. It has two flower buds, but I think it will need a few weeks until the flowers are open. I have sown B. coccinea last year, one seed has germinated, but the seedling was killed by funghi. I will try sowing B. coccinea again in March.
Last year I have tried to make a cutting of B. ericifolia, which was sucessful - it seems that it is not too difficult to propagate Proteacea by cuttings.
I had a look at your topics of Proteaceae with great interest - do you have some pictures of Hakea victoriae? This one I will also try in spring - I have made the experience that Hakea are more easy to grow then most other members of the Proteaceae family.
