Moonglow Seeds

Moonglow Seeds were introduced in the 1.0.5 patch.

They can be found when harvesting Moonglow. At night, fully-grown Moonglow will (as its name implies) give off blue orbs of light: it is at this time that you are almost certain to get 2-3 Moonglow Seeds by harvesting the Moonglow itself.

Moonglow Seeds can be placed in empty Clay Pots or Jungle grass and grown into additional, harvestable Moonglow. Potted Moonglow will grow anywhere, not just in the Jungle biomes, but is a slow to mature plant that only grows during nighttime hours.

Keep in mind as of 1.0.5 you can no longer harvest flowers or herbs out of Clay Pots with a standard bladed weapon; instead, use your Pickaxe and left-click on the flower or herb above the Clay Pot you wish to harvest out of.
