Field notes & historical context
Emirgan Park is the public face of the city's tulip season.
Outdoor rows typically hold color for 2 to 3 weeks in April before growers deadhead the blooms so energy returns to the underground bulbs.

Safety & responsible visiting
Commercial bulb fields are working farms. Never step between planted rows—foot traffic crushes stems and spreads soil-borne bulb viruses. View from public lanes or designated display gardens.
Natural phenomena depend on live weather, local access rules, and habitat conditions. Verify local advisories before travelling.
