Re: Philo mello-barretoanum

From: "Jared R. Shortman" <jared at libcong.com> on 1998.06.14 at 14:22:01(2299) One should not assume plant hardiness based off of the nativity of a plant. Sometimes you can guess from a plant's climate, but look at some plants that in nature never receive freezing temperatures, yet are hardy in cultivation where temperatures dip lower. I use the example of Macfadyena unguis-cati (not an Aroid sorry), native to deep, mesic tropics, yet weedy even here in Tucson, Arizona USA where plants have been subjected to temps in the low teens without a problem. In fact neither does extreme drought seem to be a problem, or Round Up (I have known a few who did not want it in a spot due to its tenacious growing habits (it will grow over about anything, houses, trees, much like Boston, or English Ivy). When a plant is hardy sometimes it is genetic selection for sure, however just because a plant has not been selected for a certain trait in its environment doesn't mean it won't posses that trait. Especially if there is not particular reason NOT to have cold hardiness. I tend never to assume a plant is less hardy based off its environment, especially if it related to a plant that is hardy.
