Table 1. Overview of locations, times, and sample sizes for data acquisition.

Trait category	Location	Acquisition time (year, month, duration)	Nesting and intended total sample size	Realised total sample size	Replicates per group (breeding treatment × sex × origin combination)	Reason for sample size reduction
Spatial flower traits (synflorescence height, flower number)	Greenhouse and common garden	2019 Jun., Jul., Aug. 5 days, respectively	Two breeding treatments × 2 sexes × 5 maternal families × 8 populations × 2 origins=320	316	36–40	Four individuals died
Flower scent	Greenhouse	2019 Jul. 8 hr	Two breeding treatments × 2 sexes × 3 maternal families × 8 populations × 2 origins=192	192	23–35	-
Flower colour	Common garden	2019 Aug. 2 weeks	Two breeding treatments × 2 sexes × 5 maternal families × 8 populations × 2 origins=320	286	23–25	Four individuals died, no flowers available for remaining plants
