It follows the opening of two TUI Blue hotels in Turkey in May.
Three others are planned in Austria, Germany and Italy.
"I am delighted that our efforts for global growth are bearing fruit and we are able to offer our customers the first TUI Blue hotel in the western Mediterranean with our TUI Blue Jardin Tropical," said Artur Gerber, managing director TUI Blue.
The former Puravida Resort Jardin Tropical will be converted for the winter season.
TUI Blue Jardin Tropical will offer 'the typical concept features', said the operator, including 'modern architecture, the comprehensive "Bluefit" concept, a typical regional and balanced cuisine, innovative technologies and individual services by the Blue Guides'.
The Moorish style hotel is located on the rocky coast of Costa Adeje, featuring a panoramic view of the sea and direct access to the promenade and numerous retail outlets. It's about 400 metres from the beach.
The four-and-a-half-star hotel offers 390 rooms, four pools and free WiFi.
