I am looking for seeds of your best nectar and host plants in your gardens. You see, i am trying to attract butterflies found not in my area of the LRGV (Lower Rio Grande Valley) of Texas but are found right outside it. I was wondering what everyone's opoinion was about their best nectar and host plants. If anyone can share some seeds with me for an SASE or SASBE and I can grow them maybe I can attract the butterflies.

The butterflies are:
Eastern Tiger Sallowtail
Two Tailed Swallowtail
Red Spotted Purple
Viceroy
Mourning Cloak
Ruby Spotted Swallowtail
Zebra Swallowtail
Harvester ( I know they feed of aphids but what plant would do good for getting them)
Garcia Tiger Swallowtail
Spicebush Swallowtail
Palamedes Swallowtail
Polydamas Swallowtail
AND MORE.

I am looking for the best nectar and host plants for them(all butterflies).

Here is the link to a page with all the host plants.
Note- It does NOT list all nectar plants.
Plus I am looking for nectar plants of all over Texas and the U.S. Same goes for hosts.

Thank-you,
Danny
