Asclepias incarnata : New Jersey : 15OCT19 : AK-23 : 10 posts by 2 authors. Attachments (6)

Seen in my friend’s garden in New Jersey, in the first week of July,17.

yes milkweed. I thought you just showed this plant a couple of days ago.  

the red flowers in background seem to be beebalm. are they? do you have in focus pic of those red ones?

unlike that yellow milkweed you had from Niagara this one grows vigorously on its own. better for butterflies

Is Asclepias syriaca and Asclepias incarnata the same Species?
I had no idea. The color of the flowers is also different.
Asclepias syriaca was growing wild where as the above is a cultivated one from my friend’s garden. 
Since all these are new to me and I have no further knowledge of plants from the US, I posted on the group for validation.
Yes the red flower is a Beebalm, there was only one flower on that plant unlike the pink ones, which were many.
I will search for a picture.

The yellow/orange was also a cultivated one.

are you supposing that milkweed is a proper noun?

I understand all these are commonly known as Milkweeds.
I am only trying to understand the different Species since they are all new to me. 

google is a good place to learn and try to learn about butterfly gardening, google. it will tell you what is being planted now

so take your timeand tell us what you find from my suggestion
