Every winter, my curry leaf plant yellows and languishes like the poor subtropical darling it is. And every spring, just as I'm wondering if I should do something drastic to rescue it, it puts on an amazing spurt of coppery green new growth. This year I think it may even have flower buds!
My namesake, the bay tree (Laurel nobilis, I think) does the same thing. I'm usually considering purchasing dried bay leaves to prevent defoliating the poor love completely when all of a sudden, there's a flush of big new leaves, bright green, floppy and impossibly soft, which gradually toughen over summer into the deep green adult foliage, the ambiguous flavour of which is strangely essential to soups and stews.
