'Silver Arrows' seems to be an Altman Plants cultivar, from what I can tell, and I'm not sure it's particularly different from the subspecies, but we can add it to the database if you so desire.
Photos here of a single fruit on this plant:
The last time it fruited there was only one and there were no viable seeds inside. If you look carefully at the first photo there are tiny white bugs all over the plant. I have been unsuccessful in clearing this bug problem using soapy water and a systemic, and I'm not real happy about there being an ongoing source of pests on the patio.
