For September, we still have Maxsea as a permanent option.
If requesting Maxsea as your bonus, you'll receive 1/4 tsp, enough for a gallon of solution. A normal request would net you 1/2 tsp.
Next, typical, albino, or mixed Capes will remain an option for a bonus.
Lastly, all of the numbered Sarrs are going to continue to be an option. It's still a little early, but you can store them in your fridge until you decide to stratify them, and you could naturally stratify them if it gets cold enough where you live. As the Sarr seeds are class two, you still need to be eligible to request them in order to get them as a bonus.
