For September:

Common Name:  NARROW-LEAF MILKWEED                                                         

Botanical Name:  Asclepias fascicularis

The good news is that this plant is a must for every butterfly garden because it is a favorite nectar plant for adult butterflies and a host plant for Monarch butterfly larvae. It is very tolerant of many types of soil, even clay.

The bad news is that it is a host plant for Monarch butterfly larvae and these hungry creatures will eat it down to the ground!  It is also winter deciduous and will lose all its leaves.

Planting suggestions:  This plant should be placed in the background rather than as a centerpiece in the garden. Plant a number of plants in proximity as sufficient food for larvae.  Will naturalize in the garden.
