闪耀根种子 are obtained by harvesting 闪耀根 while it is blooming. A Blinkroot plant switches between its blooming and non-blooming state at random. Its blooming state can be identified by the yellow dots on the ends of its fronds and the blinking light it emits. At this time it will drop 1-3 Blinkroot Seeds when harvested.
Blinkroot Seeds can be placed in empty 粘土盆s or on bare 土 and 泥块s and grown into additional, harvestable Blinkroot. Potted Blinkroot will grow above ground, in houses, and even in direct sunlight. Unlike other plants, Blinkroot matures quickly. Use a Pickaxe and left-click on the flower or herb above the Clay Pot to harvest it.
