Hyacinth Bean Vine

What is the best way and time to plant hyacinth beans? I live in Zone 5.
Doug says indoors in mid-March at 2 beans per 4-inch pot. This is a slow growing annual bean that will not bloom until very, very late in the fall from mid to late May outdoor planting. Earlier plantings into cold ground will simply rot off.
If you won't want flowers, then plant them as soon as the ground is warm enough and all danger of frost has passed.
Planting is the same as for any bean - put it about 1/4 to 1/2 inch deep, cover with soil and keep damp and warm.
