Both the dawn redwood and the swamp cypresses enjoy moist to wet conditions and loose their needles in winter. The dawn redwood resembles its American relatives the swamp cypresses ( Taxodium). The tallest of these trees are now over 20m (65 ft.) Mustila Arboretum was among the first to receive seeds, and plants grown from these seeds were sent to Gothenburg Botanic Garden as early as 1952. Understandably, several seed collecting expeditions were made to China in the late 1940s. Due to the war, it took two or three years to confirm that they were the first living individuals of the genus, the dawn redwoods.
