Livewell On The Wind

"Where [Tabitha] stood, a hillside sloped downward, decked with smaragdine susin, starred with chasuble bush and Buddha's cup, to the strewn and begardened city, the huge curve of uprising shoreline, the glitter on Falkayn Bay. Small cottony clouds sauntered before the wind, which murmured and smelled of livewell."
-Poul Anderson, Rise Of The Terran Empire (New York, 2011), p. 647.

Three senses: colorful flowers and glittering bay; murmuring wind smelling of livewell.

These might be the only sauntering clouds anywhere in literature?

The extraterrestrial plants named in this passage are:

susin;
chasuble bush (see "In 'Wingless'" here);
Buddha's cup (see "In The People Of The Wind, Chapter One" here);
livewell.

In particular, Avalonian livewell weaves in and out of the narrative and I have tried to chart the references to this flower in earlier posts. "Buddha's cup" is obviously an evocative and colorful name bestowed on another native flower by human colonists of Avalon.
