Last week, I got C. australasica seeds of three different unidentified varieties. To my surprise, the seeds germinated very quickly and at the very present I have 15 seedlings (probably more seeds will germinate):



I wonder how many years would it take before this species reaches the fertile age? And does anyone has information about it's grafting compatibility? I've understood that it is compatible with trifoliata - but what about mandarin and lemon fe?
