Asparagus and rhubarb take a few years to become established, but once they do, they reward your patience abundantly.
Both vegetables are well-adapted to home gardens in this region, are easy to grow and provide delicious eating for over a month each spring. One planting produces food for a decade or more.
Asparagus is native to Europe and Asia and has been cultivated since ancient times. Because it has been widely-grown and is so suited to this region, asparagus is found growing wild in many places from bird-dispersed seeds.
Asparagus can be planted now from crowns available at garden centers or from seed catalogs. The crowns are generally placed about two feet apart in a one-foot wide trench about eight-to-twelve-inches deep. Spread the long, rope-like roots out over a mound of compost at the bottom of the trench. Cover the crowns with soil and/or compost, but don't fill the trench all the way until the plants have grown well above it. Keep weeds away by hand pulling or by mulching the plants with hay or straw. Cover the bed with compost in the fall to nourish the soil.
For the first year or two, just let the asparagus grow without harvesting. The plants need to build up a large reserve in their roots to be able to keep sending up shoots, even after repeated cuttings. By the fourth year, asparagus can be harvested for a month or two until the new spears are reduced to the thickness of a pencil. Once harvesting stops, the spears grow into the beautiful five-to-ten-foot-tall, feathery foliage which creates the nutrients for the following spring harvest. A well-cared for asparagus bed will produce for decades.
Although we sometimes eat the spears freshly picked from the garden, we really like asparagus lightly steamed, with just a bit of lemon juice, olive oil and black pepper.
Rhubarb, another perennial plant worth waiting for, is native to southern Siberia. A relatively recent addition to western cuisine, it was growing in America by 1800, and is even easier to care for than asparagus. Pieces of rhubarb root available at garden stores can be planted this time of year. Dig a large hole, about the size of a bushel basket, and fill it with plenty of rich compost around the root. Space rhubarb three-to-four feet apart. Rhubarb also appreciates an annual application of decomposed manure or good compost.
Plant this spring and you should be able to harvest a few stalks next year. After that, expect each plant to produce 10 to 20 stalks per year for the next ten years minimum! Combined with June's strawberries, rhubarb makes a exceptionally tasty pie.
This spring, set out a few of these two delicious perennials for many years of good eating.
