How cold does it get in winter? There's quite a range of tropical deciduous
legumes that drop their leaves to cope the with long hot dry season, from
shrubs through to tall fast-growing trees. Most of these can coppiced
regularly through the leafy time of year to build up a good mulch layer.
Some spp can handle a reasonable amount of frost while others are quite
frost sensitive.
