My Mom and I are asparagus lovers, and I have been growing 'Mary Washington' for several years now. We are both very happy with the flavor, though I can't wait for it to get a better stand!
I have read that asparagus is hardy in zones 3-10. Asparagus likes a lot of mulch, so in late fall I put a lot of shredded leaves and compost on it.
Perennial grown for tender edible new shoots that appear in early spring. I put in twelve crowns last spring and let them go to flower and seed over the summer. About three fruited (red berries form along the stem)-- this is supposed to be a variety with fewer females ie. more shoot-forming energy, less seed-forming. This spring I already have about a dozen 1 cm x 15 cm spears-- they are delicious! Needs a permanent dedicated spot-- mine are in part shade.
