Morphology
Helianthus + tuberosus
This is a Latin binomial combining the genus name Helianthus (sunflower group) with the epithet tuberosus (literally 'tuberous' / bearing tubers). If a learner knows both constituents, the meaning 'a Helianthus species that has tubers (i.e. a tuberous sunflower / Jerusalem artichoke)' is directly derivable, and the genus+epithet logic is cross-linguistically regular in scientific names.
Etymology
Helianthus tuberosus comes from Latin words that describe the plant. Helianthus means 'sunflower' because its flower looks like the sun, and tuberosus points to the knobby underground 'tubers' people eat. So the name literally says it is a sunflower with edible tubers, the parts often called 'Jerusalem artichokes'.
