There is–it’s just not called “gardens”. The Rachio team very smartly realized that there are too many variables to have just one zone type.
For setting up veggie or flower gardens, there are choices for annuals or perennials. Vegetables are mostly annuals, with cool season and warm season varieties. A few exceptions would be asparagus, artichokes, rhubarb & horseradish, which are perennials.
I love the fact that I can choose soil type and type of spray head or emitter and sun exposure among other settings.
As for flower gardens, well–there’s too much to cover in this post, but flowers can be annuals, perennials or biennials. Depending on the geographic location and climate a flower may grow as a perennial in one location or in another location, act as if it were an annual.
Kudos to the team for providing so many possible choices so each user can customize settings for optimal watering.
If you want to post a specific question, I may be able to offer some suggestions.
