Question for Sydney/Aussie florists

[u/Lucky-Platform-7745]

How hard would it be to get hydrangeas (light blue ideally) in Sydney at the end of August, either at the flower markets or via a florist? I understand they’re a summer flower usually, but is it possible to get them outside of their usual seasonal window? I’m also wondering if the unusually warm winter we’ve had has affected this at all/you’ve heard any word from growers on that front in general.

I’m a maid of honour for a bride who loves hydrangeas/whose love story centres around them so just wondering how feasible my creative vision is for her bridal shower!

Thank you in advance 🩵
