Gardening - Harvesting

[Phlange]

So far when I crossed Dzemael Tomatoes and Dalamud Popoto Set, they've given me a chive seed every single harvest. I've planted a full garden, then harvested the tomato and planted another round. So I got 12 chive seeds from just 1.5 cycle. All used grade 3 Than soil. (And i did replant the very first tomato).

Are you able to confirm if this is a two-way cross?
