Tulip

Tulip is the proprietor of Underworld Outfitters and is one of the characters that Railway Rifle schematics can be purchased from. According to other Underworld residents, many people don't purchase items at her store and she is not very successful. A few of the other residents hint that she is interested in Satanic folklore. She reveals that she spends her caps at either Carol's Place or The Ninth Circle. However she prefers Carol's place, and dislikes The Ninth Circle.

She gives the book Paradise Lost during the conversation when asked for the Underworld's origins. Reading this book increases Speech by 1 (or by two if you have the Comprehension perk), as if it were a copy of Lying, Congressional Style.

If you have the Lady Killer perk, you may seduce her, following a successful Speech test. This has neither benefit nor drawback, aside from a Stimpack she gives the player afterwards. But still, why would you want to?

Trivia

 * Tulip wears the same outfit as Bittercup from Big Town. Both these NPCs also happen to have names similar to flowers (well, Tulip is the name of a flower and "Bittercup" is a bastardisation of "buttercup", a type of flower) and have similar personalities (for example: both are attention-needy).
