Gardeners' Notes:

I planted Jersey Knight crowns in my asparagus bed a couple of years after starting the bed with Mary Washingtons.
I believe that the J. Knights bear more harvestable speers than M. Washington, but I can't tell one from the other for sure until late summer when the M. Washingtons produce red berries. I continue to enrich my 5" x 16' bed with leafy compost, cow manure, and rotted sawdust. This spring we are enjoying an early harvest of plump, delicious speers, due to warm weather and plentiful rainfall since March.

I decided to start this plant from seed. Every seed that I planted came up. I'll see how good they grow further in the year. They show good potental right now.

Adapted to temperate, warm and cool climates. High yield potential with very high marketable yields. Spear size and color is comparable to the Jersey Giant. Very high rust resistance.
