After you complete the Sprouting Seedlings World Quest, you must find 12 Vasmrtis to fill Aranakula's garden. This task is not required to complete the Varuna Gatha section of the Aranyaka book. Further World Quests will be available in the story of the dream nursery.
Where can I find all 12 Vasmrtis in Sumeru in Genshin Impact?
Vasmrtis can be harvested when you complete nursery puzzles scattered throughout Sumeru. All 12 puzzles can be completed in any order. Do not use Teleport Waypoints that lead you to underground caves.
Reference the above image to find six Vasmrtis in Sumeru's northern half.

In Sumeru, Genshin Impact, how do I solve Vasmrti nursery puzzles?
Upon reaching the above locations, you'll encounter a glowing patch of grass. Step on it to stimulate more patches of grass to grow. Your aim is to continue following the grassy route until you reach the flower at the end. There are still some rules you must follow.
The following image shows the difference between grass-covered and ungrashed areas. Again, you cannot walk on grass patches.
Go to the first glowing patch to stimulate grass to sprout in nearby areas to solve a Vasmrti nursery puzzle.
The puzzle may reset if you don't repeat the same pattern until you reach the flower. Be careful not to step on the same patch twice. You also can't exit the grassy path.
If you miss a flower, you'll receive a Vasmrti and a Common Chest reward. Don't worry if you make a mistake at any point in the puzzle. You may try again as many times as you need.
