The Mexican Swamp Cypress is such a fabulously charismatic tree in the wild where it forms a more pendant branch habit than its American cousin and trees of vast trunk sizes can be found, without the knobbly 'knees' or pneumatophores from the roots. Foliage is slow to fall in comparison with T. distichum and turns to a vivid tawny-orange in early winter rather than autumn. Kew has a 100yr old specimen, so it's completely hardy here. Easy at pond edge or in ordinary well drained soil. This represents my own collection, from Coahuila State, Mexico, in 2009.
