Hi Robert I have planted Grevillea banksii seeds I just put them into a small tube filled with potting mix they dont have any trouble coming up, sorry cannot remember just how long they take to sprout, as now I get so many seedlings under my trees I just pot them up instead.Have a look at the link below it reads the seed of the Grevillea sprout readily when planted in a warm moist environment....MM |
