Yeah I can send seeds overseas from Australia but not supposed to receive them. Australia has a long list of allowed plants and as a collector of rare succulents I see the high import fees for allowed seeds and plants as a big government cash grab.
If you want some Eucomis I can send for the cost of postage plus $1 for 10-20 seeds. That would make it about $4 in USD. Message me if you want to give it a try. If you have succulent seeds let me know.
Yes Knips are true to seed. At least mine have been.

@seedfork let the seeds mature on the plant.
