More about this plant

Agapanthus praecox is a popular garden plant around the world, especially in Mediterranean climates. It is native to the Kwa-Zulu Natal and Eastern Cape provinces of South Africa. Local names include agapant, bloulelie, isicakathi and ubani. Most of the cultivated plants of the genus Agapanthus are hybrids or cultivars of this species. It is divided into three subspecies: subsp.praecox, subsp. orientalis and subsp. minimus. Wikipedia →

How we know this (2) Methods & honest limits
Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.

Kattge, J. et al. TRY plant trait database — Categorical Traits Dataset (2012).
Flower colour Derived

McKenzie et al. assigned each species a flower colour with a GPT-4V vision model over iNaturalist photos. We use the confident tier plus a separately-labelled lower-confidence top-up (mostly inconspicuous green/brown flowers), and render it as a small tint — never as an asserted fact, and kept out of the written synopsis.

Honest limits: AI image inference (~87% expert agreement on the confident tier); a decorative, confidence-tiered indicator, not a measured trait.
