Apium graveolens rapaceum
September - December
While celeriac may not win any vegetable beauty contests, don’t let its homely appearance fool you. Underneath its knobby skin exists a smooth, white flesh with a nutty, earthy if slightly bitter, celery/parsley flavor. Though little is known about its history, celeriac originated in Europe, where it is still popular. Celeriac is generally available at farmers markets from September to the end of the year. If you decide to grow it at home, it can take 6 months to mature.
Nutrition: Celeriac is low in calories. It is also a good source of potassium, vitamin C and vitamin K, which is important for maintaining bone health. Preliminary data also suggests that vitamin K may also help prevent Alzheimer’s disease, although more research is needed to prove this link definitively.
