Experienced grower's notes on Hornwort

I've been growing plants seriously for over fifteen years and Hornwort remains a reliable favourite. For anyone starting out: the most critical thing is dividing overcrowded plants every two or three years in spring. Everything else follows from that.

overrunning the pond surface in productive warm summers is the challenge that trips up most beginners and some experienced growers too. I've been growing mine in a natural wildlife pond with naturalistic marginal planting for three seasons now and the results are consistently good. essential habitat and breeding ground for pond wildlife is what makes it worth coming back to year after year. peak flowering period in midsummer is when I show it off — it earns its place fully then.
