Dahlia
Let an agent explain dahlias and their botany and cultivar groups, support growing, propagating and overwintering dahlias, describe shows and classification, and describe history and cultural significance.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain dahlias and their botany and cultivar groups, support growing, propagating and overwintering dahlias, describe shows and classification, and describe history and cultural significance.
A genus of bushy, tuberous, herbaceous perennial plants native to Mexico and Central America, national flower of Mexico, cultivated worldwide for their showy flowers in thousands of cultivars classified by flower form into groups such as single, anemone, collerette, waterlily, decorative, ball, pompon, cactus and semi-cactus dahlias; dahlias are grown from tubers, flower from summer to frost, and are popular in gardens, cut flower production and competitive shows.
What it is for: Tuberous flowering plants of the genus Dahlia.
It can be explain botany and groups; support cultivation; describe shows and classification; describe history.
