Just a note on the various milkweeds. I have 2 varieties at the market, swamp and tropical (annual), and sometimes a butterfly weed. Most people with small urban yards don't want the common as it does spread by rhizomes and can be problematic. I have the swamp aka rose in my yard, and still hasn't bloomed, perhaps in too much shade. Next year! I suggest the tropical can go in pots or ground. I have a couple of butterfly weeds that have been in ground for a number of years, and no Monarch cats. I did hear from a native plant grower (from middle TN) that they don't like it as it is coarse and hairy. Last summer did have a couple of cats on the swamp, and as plants were young had to move starts of tropical and swamp around to get enough food.
The honey vine is a 2 edged sword. It can take over, try to strangle a shrub. I have a mess in the camelia (tall thick shrub). I'd pull it off, but may be taking cat food. But then cardinals and mockingbirds both go into the shrub foraging, and probably eating most anything that moves. A friend in Nashville has spotted a couple of Monarch adults laying eggs on his honey vine (sent me pics of one laying the egg). This person does extensive butterfly watches/counts, and came upon a patch of swamp milkweed covered with monarchs and other butterflies. Now he wants more in his yard! (as I am starting these from seed could be his source for plants!)
This season have many more milkweed plants, and have spotted perhaps 5 Monarchs! Sigh.
