More thropies for you, BlanchP

Demure as seed spent tulips, dear as Amsterdam ones
Hot as rising daffodils in late-spring frost
Selfless love: a trodden violet
Kind as valley lilies, scent unseen
False-morels false
fadle as fiddleheads

And for a other seasons:

Mad as datura
Proud as anthurium
Two-faced as amaryllis
circum-spect as peri-winkle
and
[androgynous as mating fern]
