Bellagio Conservatory & Botanical Garden is the sky-lit atrium at Bellagio with vibrant and fantastical scenes composed of plants, flowers and trees. The airy central conservatory was inspired by the Art Nouveau conservatories of Paris. Each season, a 120-person team of professionals creates displays with more than 10,000 flowers, which are regularly switched out to maintain freshness. You never know what to expect: giant flower sculptures celebrating the New Year, koi ponds and pagodas, enormous jade medallions and animatronic figurines, whimsical architectural elements and fantastical scenes.

As a botanical artwork and internationally renowned centre of scientific studies, Lalbagh Park contains a diverse variety of flora, a deer park and one of the largest collections of rare tropical plants within India.

An annual flower show is also held here, in the British-built Glass House.
