There are lots of theories, nutrient balance and too cool temperatures being two. I personally think that the clones of subcalva we have in America may be infected with some weird virus. Carol has had hers tested and the results were negative for most of the common viruses, like tobacco mosaic, but I wonder if this isn't some really obscure virus that isn't common on cultivated plants. That's just my guess, of course. When everything is perfect for subcalva it grows okay for me, but if even one thing stresses it out this is the result, That is true of some other plants that have viruses, like passiflora 'Incense' and some Cannas.
