I'm looking for fresh Katuk seeds. I was gifted about three white Katuk fruits from ECHO last year, and obtained about 6 seeds total. I planted them three weeks after they were harvested (keeping them within their fruit until just before planting time), and one of them actually germinated successfully. It has become a decent-sized bush in a year, and I have already taken cuttings from it. The bush has been flowering profusely since it was about 3 months old, but it has never produced a single fruit, so I'm guessing they require cross-pollination with another genetically-distinct individual.
I was strongly cautioned NOT to grow the plant from seeds while at ECHO, but apparently success is possible with very fresh seed. I'd be interested in some seeds next month ( late September) if anyone can time some fruiting for then.
