I love Alberto's observation about immature corms "learning" faster than mature ones (see below). I've been reading about phenotypic plasticity this year (the quality that lets an organism of a given genotype alter its appearance, physiology, whatever (i.e. phenotype) in response to different environmental stresses), and it's absolutely fascinating. It amounts to saying, in laypeople's terms, that yes, indeed, a plant does "learn" (and this triggers short-run adaptation). It's great stuff, and a lot of what we observe in our gardens/greenhouses makes sense when we view it as evidence of plasticity. For an introduction to the subject that is somewhat accessible, I recommend Massimo Pigliucci, Phenotypic Plasticity: Beyond Nature and Nurture (Baltimore: Johns Hopkins, 2001).

Hi Scott: Thanks for your interesting comments. A common mistake is to try that adult corms change Hemispheres. Inmature corms are a lot more flexible and adapt a lot more readily to favorable conditions for growth. Regards Alberto
