I ordered seeded eucalyptus and silver-dollar eucalyptus from Whole Blossoms. I was SO relieved to find out that they were selling it in June, as many vendors only offered eucalyptus through May.
I requested delivery for the Wednesday before the Saturday wedding; the seeded eucalyptus came on time, and the silver-dollar showed up a day late. Since I planned for some flexibility, this wasn't a big issue, but just a heads-up. I would recommend ordering along a similar timeframe, just in case there are issues with shipping.
The eucalyptus was beautiful, stayed fresh until the wedding, and was 95% usable (better than expected). For the price point (especially for 10+ bunches) and the service, I would order from Whole Blossoms again in a heartbeat!
