I think the swallowtails are my favorite butterfly....yes, even over our Monarchs.
I have the Rue as one of their host plants, but this last year I obtained several citrus trees. I am so glad I didn't test them in the garden their first year. With all the freezes we have had, I might have killed them. I will plant them outside in the spring...maybe.
Anyone have any outside in North TX? How did they do through the freezes and snow this year.
I have a Lime - noid has thorns
Lemon - Improved Meyer
Orange - Satsuma
This is the Lime tree when it started to bloom last year.
