I hadn’t looked at the saffron crocuses for over a week, so thought there might be a laggard blooming - 21! A real crop! There were 11 cut Oct. 29 and one Nov. 1. We now have enough to try cooking with 'em.
I bought 24 for $19.00 eight or ten years ago, from White Flower Farms, My wife and I have divided them twice in that time - plenty of little starts surround the fat corm. Only the larger corms bloom - at least 1/2 inch across - and live one or two years at that size before collapsing. We’d have more if we didn’t share 'em with colleagues and friends to grow themselves.
We’ve got them in reasonably fertile soil and buried under about an inch or two of wood shavings. 9-10 months of the year, that patch is bare - except for the weeds I must pull and apply more mulch. Leaves come out late April, die back and the corm stays dormant through the dry summer until leaves emerge again late September. Then the blooms. Some years they are covered in snow and I don’t see 'em.
This might be about as far north as they can be cultivated.
