Here is a picture of an Earthen flowerpot, and blooming Grain seeds.
To the left you have a Porcelain flowerpot and to the right you an Arcane flowerpot. Both have tree cuttings planted inside. When gardening with tree cuttings you'll notice it takes a very long time before they're ready to be harvested. You might think when you have yours grown to the size of the one on the left, that it'll soon be ready to be harvested. You'll be wrong, as the plant still grows even larger, to the size of the one on the right. It takes about a rl week before it grows from one size to the other, so you can imagine how long it takes it to grow from a mere seed.
