It's supposed to only grow in moist soil, but it seems happy on my sandy loam - I think perhaps the last two very wet summers have had something to do with it. But last year it out-survived a common-or-garden Shasta daisy planted alongside: a shame, since the Shasta daisy finished just as the Leucanthemella began, so they made a great partnership.
I can't complain, though. This tough, easy-going plant is just soldiering on through: it's been flowering its socks off for nearly a month now, and shows no signs of flagging. Its teacup-sized flowers have a subtle smoky-green centre, fringed with yellow, that gives a touch of sophistication to all that cheerfulness, so even the most painfully stylish can grow it with confidence. But I just love it for giving my day such a lift but demanding so little in return.
