Deadly milk-white trumpet
Deadly milk-white trumpet is a toxic I.C.E. Age shrub that does not have a transitional replacement term or modern documentation. In the late summer it is supposed to bloom with huge pale flowers releasing pollen. This pollen is a level 7 poison that causes 4 to 8 days of nausea and blindness if the warding is failed by 1 to 100, and causes madness if failed by worse than +100. Its black seeds in mid-fall when ingested cause euphoria and false surety in battle. Its presence in The Graveyard is probably symbolic for seasonal reasons, similar to the spring lethal salorisa covering the burial mound.
I.C.E. Age Example
The milk-white trumpet is said to grow in unusual concentrations in the shadows of evil strongholds. This is just north of a room describing the shadows of the crypt:
[Graveyard] Weeds striving to grow between the gravel, and the thorn bushes and milk-white trumpet shrubs obscuring the foundation of the crypt provide the only clues that life goes on amid the desolation. Wisps of tattered cloth and stray tufts of fur are caught upon the thorns. Several intact gravesites lie to the east. Obvious paths: north, east, south
Behind the Scenes
Deadly milk-white trumpet appears in the Shadow World Master Atlas: Inhabitants Guide (1989) book on page 10. This is also the source of the salorisa, dreamvine, delphinuris, spinewood, and sirenflower that appear in The Graveyard. "Angel trumpet" refers to real-world toxic plants, such as Brugmansia or Datura ("devil's weed"), closely related deadly nightshade.
