Requiring minimal input from me, and proving hardy here even in my cold and heavy 'Devon Red' clay soil (surely another bonus!) it is always late to emerge after winter. The new shoots don't usually appear until mid / late June, just when you start to wonder if it is going to make a reappearance at all.

Some of my plants also have clusters of berries forming, small, hard and green at present, although they will ripen, swell and turn red later in the year. I'll sow the seed and bring on the next generation. Young plants have a distinctly different leaf shape - known as a hastate shape. Once into the 2nd or 3rd year, the leaves should take on the 'adult' shape and become more recognisable, and after 4 or 5 years, the corm should reach flowering size. So is that a long time to wait for a spathe from seed? Well, yes, I guess it is. But is is surely worth the wait!
