The abbreviation subsp. means subspecies (subspecies) and sesquipedalis is made up of sesqui = one and a half and pedalis = “belonging to the foot”, which may indicate the 1 1/2 foot long pods.

In our part of the world, the species does not produce any lasting benefits. The plants grow up from seeds, bring their pods within 3 or 4 weeks in mid-August, which quickly develop seeds.

Later pods grow back here and there, but not in significant quantities. In terms of home-growing, the asparagus bean is a delicacy that is available for a short time. 

But since we don’t have to worry particularly about the culture and because we can easily get seeds for the coming year, the cultivation gets its value accordingly.

Planted in dried, germinated or seedling grains , depending on how long the seedlings are needed. Germinated beans are placed in holes carefully because they are vulnerable.

Indicator of element deficiency: the appearance of yellow spots on leaves and pods. To avoid this, a small amount of rotting bird droppings is put into the beds or sprinkled with wood ash.

Further care and harvest

As mentioned above, even day and night temperatures around 25 ° C are ideal.

If these conditions are not met, then the plants will not grow much, but if we come to the said optimum, then everything goes very quickly and suddenly the trellises are full of meter sleeves. Especially in the period of the main growth, the bed should not dry out too much, but should be watered regularly.

This is all the more true for the time of harvest, because otherwise the pods become tough, ripen and dry out too quickly.
