me again graley,
just to start you off we have this one:
Cattle Bush - 'Pittosporum phillyreoides'
it looks like it has the growth habit you are looking for.
these ones like it very well drained not sure about all the others but
would assume they would be the same.
snipped
With peace and brightest of blessings,
len
