g'day bryan,

they will grow from seed, if you are only wanting a different probably
somewhat plain tree in your garden it could be a good project. if you
are hoping for fruit the same quality that the pip came from that is
the big unknown for the main most info' indicates that seedlings may
bare fruit of such poor qulaity as not to be desirable to eat or never
bare fruit at all and in some cases they have been reported to have
given good qulaity fruit at times.

they are a large to very large tree.

alos you may have to wait for quiet a long period before you see any
fruiting results from seedling it could take 12 years give or take.

if you are wanting quality fruit in shorter time buy a grafted plant,
you can have fruit in 5 years or less, i have a tree been 2 years in
the ground and about 2 meters high with it's first fruit on it. select
the variety that will suit your growing conditions the best.

snipped
With peace and brightest of blessings,

len
