How to care for it
The 20-year vegetable: dig in compost, plant crowns 8 in deep in a trench, and fill gradually as spears grow. Don't harvest for 2 years, then cut for 4-6 weeks each spring. Let ferns feed the roots the rest of the year.
Good companions
Tomato, parsley, basil
Harvest
Cut fat 6-8 in spears before tips open, spring only.
