Original provenance naturally occurring self-set shrub on upper fence-line of Kingston Park's cliff-face botanical reserve/CP. A common plant here and highly ornamental ,ideal as feature coastal cottage garden shrub (2nd line, needs some protection from salt-laden winds) in my view.
Edible fruits a bonus,but sets fruit less often and less prolifically on Fleurieu and other coastal sites near Adelaide than it does inland in semi-arid regions,and on coastal sites further west in SA.Also insect pollinated so lone specimens-both wild and planted- with few others within the local area may not set any fruit for decades despite flowering profusely most years.Fortunately a long-lived plant, and can also form copses or small dense thickets by *root suckering.
*[An excellent example is the outlier occurrence in the northern Normanville Dunes swale, where 100s of plants occur-many very small or stunted by repeated grazing by rabbits and other herbivores-over an area of @ least a hectare.Some were lost during the sand mining phase which finished some decades ago, but the seaward bit of swale( about 1/3rd of the original width of swale) was left intact, so maybe about half the original number of S acuminatum plants remain.(Some of these 'saved' trees growing nearest to the mined edge died quickly from root disturbance,moisture stress etc, and some are still recovering,but that's progress, as we all know. I am truly grateful the genome was not annihilated, which historically was on the cards till the 11th hour). It has been suggested to me (by several persons better qualified than me) that this outlier population may all be a single genome i.e. one plant with extensive underground root system connecting all the 'saplings' to the very old,mature few shrubs/small trees which are(or were) roughly in the middle of the area in question.
I think that is probably true,given that I've visited the site almost annually since age ~15 (I'm now ~64) and seen them flowering in most years,but not once have I seen fruit on them, and I've often scratched around in thick leaf litter under the best and oldest specimens without ever finding a stone(I wanted to germinate some for my wirra),or even a fragment of one!! Cross-pollination would seem critical to reproductive success for this taxon, if the above suggestion is indeed the case)
