I would lovee to see the garden updated and stocked with some new seeds.
I think it would really help the artists if you suggest some seeds and plants you'd want to see.
Not sure if it would ever be considered but it might be nice if we could grow flowers for Vesnali or produce from the Fresh and Flavorful. It would mean more of those items in circulation but if the flowers could only be grown during Vesnali and the produce grew slowly it might balance it out.
Other than those. Maybe new and current flowers could be combined to create a variety of garden layers to build settings for our HAs. Or ingredients that could be used in crafting baked goods at Fantine's Bakery. That way it ties into other aspects of Subeta and has more purpose than filling out your pets treasury. The gardens could be themed after seasons and areas around Subeta.
Overall I rarely use this feature because it is not in an area you see unless you explore the map. And the "Water Plants" link on the Dailies page is not a very good reminder. If it was tied into other features people might go looking for it. Or maybe we could have a link on the news page that featured different optional activities around Subeta each day and maybe a blurb about the feature. Specifically the less well known ones. There are so many nooks and crannies around this site that are really cool but most of us either forget, rarely use them, or never knew about them. If new users do find them on the Dailies page it isn't always very clear what benefits the activity offers.
Another change that would really help me is if the garden had a journal or some other document that showed the various seeds that could be planted and what they produce.
I'd like to see camellias added to the site in some form (garden seeds, Survival, or Vesnali!).
