Rose Sheaf
The florist says...
"Romance" - Six beautiful roses arranged in a sheaf style and surrounded by dreamy foliage.

What is a sheaf?
In mathematics, a sheaf is a tool for systematically tracking locally defined data attached to the open sets of a topological space. The data can be restricted to smaller open sets, and the data assigned to an open set is equivalent to all collections of compatible data assigned to collections of smaller open sets covering the original one. For example, such data can consist of the rings of continuous or smooth real-valued functions defined on each open set. Sheaves are by design quite general and abstract objects, and their correct definition is rather technical. They exist in several varieties such as sheaves of sets or sheaves of rings, depending on the type of data assigned to open sets. (visit Wikipedia for more on that bizarre topic)
How about...
A quantity of the stalks and ears of a cereal grass or sometimes other plant material bound together
That seems to make more sense. I can't imagine it would be very romantic to send 6 roses as a collection of compatible data in an open set in some formation of rings either continuous or smooth.
That could just be downright weird.
This sheath is a sheath sheath, you know like plants tied together except they aren't just any plants they are roses with some "dreamy foliage".
