Prickly [Senryū]

a swallowtail
lands on a thorny thistle,
resting in comfort.

Thistle [Haiku]

heavy-headed thistles
sway in the cow pasture,
bees read their motion.

Thistle Flowers [Haiku]

thistles are flowering,
looking spiky and dangerous,
yet soft and comely

Thistle Distance [Haiku]

the thistle blooms:
 beautiful for a time, but 
  best known from afar.
