Great photos, JB!
MMathis, I had aphids TERRIBLE last year on my swamp milkweed. BTW, you don't have to grow it in the water, it can easily grow in the ground, too. I have never had aphids bad on my common milkweed. I've got seeds from both of those, if you would like to try growing the common. Hint: The seeds need to be cold stratified on both of these. I.E., you need to put them through "winter" to get them to sprout. So, you can either put them in the ground/under mulch or thin layer of dirt this fall, or put them in your fridge or freezer for a month or so then plant them in the spring. Last fall, I took a whole common milkweed pod and put all the seeds from it under the mulch, just to see what happened. OMG, I must have had at least 50 plants sprout! So, I know THAT works! I also have some tropical butterfly weed and orange and yellow butterfly weed, but no seeds from those so far .... hoping they all produce seeds eventually. Time will tell.
I'm seeing lots of monarch butterflies, but so far only the one baby cat and she was released last week. Nothing since then. Last year I raised 42 monarchs to be released, this year it appears I'll be doing good to have 5. Very sad!!! But, my wild flower area I'm creating is bringing in tons of swallowtails. Next year I'm concentrating on their host plants. Although I planted dill, parsley, and fennel, the weeds overtook them, so not much there for host plants. I'll designate a large area for that next year. I bought a couple variegated willow bushes, and that's another host plant, so will see if they survive and what I get on them next year. I'm loving how things have turned out, but need to get control of the grass and weeds better next year. In time, I hope these large areas self seed and the flowers outnumber the grass and weeds. It will take a few years, but I love working on it!!!
