Cluster amaryllis

As equinoctial week approaches, the cluster amaryllises open up all of a sudden.
Some people may notice that the week will come soon when they see the red flowers.
Its bulb is poisonous so maybe that’s why it is called an unlucky flower.
I used to see them on the ridges between rice fields to repel moles,
but recently I don’t as much as before. (H.S)
