Jumbo Garden incense includes 14 choices, with Orange Flash Garden Sticks from Gonesh added in August. Jumbo incense sticks are the same fragrance as their regular sized counterparts, but they are bigger and longer and burn for hours. Burn times vary. Hem jumbos reportedly burn for 3 to 4 hours. The Gonesh sticks are garden sticks formulated to repel mosquitoes, but are not jumbo sticks.
