Is this possible? If not, why not?
Could you please be a little more specific about what types of plants you would like to be able to order? I am happy to pass on your question and/or feedback to the Bunnings merchandise team.
It is posiable, they have a list at special orders of what the suppliers have. Some plants might be seasonal so out of stock with the suppliers.
Generic barcodes can be a problem as they can cover a range of sins, aquatic plants suffer from the one size fits all barcode from my experiance and suculents may be similar. Waiting time can vary, it took 12 weeks to get a simple part to fix a clothes line, I think they aim for 2 weeks though.
Being a like to see what I am getting type person doesn't help when it comes to special orders.
I’ve seen quite a few plants come through special orders in my time.
A lot depends on the supplier and what they have available seasonally. I have personally purchased via special order a lemon / lime grafted tree so I know it’s possible, however the conversation started in the nursery, not at special orders.
Your local store should have at least one team member in the nursery who would regularly have dialogue with suppliers of plants that they can ask to see if specific plants are able to be sourced. Otherwise, you could also talk to special orders and ask them if they can do some digging around for you.
Normally Bunnings suppliers are more than happy to send Bunnings items that we may not ‘range’ in store via a special order.
Good luck !!
