These are not tuberosa as you were talking about. They are tropical milkweed. Asclepias Curassavica I do also have butterfly weed, common milkweed, and swampweed which has pink flowers as shown in my avatar.
Oh excuse me alp, i was directing my question to @CrazyConure relative to his situation at the present time. I should have made that more specific, sorryYou bought plants? and did not grow from seed? By "butterflies" do you mean Monarchs? If the Monarchs do not visit them they may have been sprayed by pesticides/insecticides if they were plants when you bought them. Florida has a year around population of Monarchs that do not migrate to Mexico in the winter. If you are talking about butterflies other than Monarchs and only have one blossom and 4 plants, they are probably nectaring on other more mature plants.
Correct, @LIcenter and thanks for clarifying. @alp, the plant that @CrazyConure is showing us and the one that he is growing is Asclepias curassavica commonly called by a number of names actually, but the common name used here is Tropical milkweed. There are many different species of Asclepias that range from the tropics up into Canada as native plants to their specific areas.These are not tuberosa as you were talking about. They are tropical milkweed. Asclepias Curassavica
It's very easy to spot the eggs on the underside of the leaves; the eggs are little yellow dots, usually laid somewhere away from the edge of the leaf.I see a few monarchs flying around outside, but I don't see them on the flower itself. I guess I'll have to wait a bit.
I don't spray anything on this plant.
I don't mean to make it sound as if it's a deep yellow -- it's not; however, it does have a slight yellow hue, much like the below pics. As for the size of the dot, I didn't mean to make it sound as if they are extremely tiny, they are very easy to spot.@roadrunner it is interesting that your Monarch eggs are yellow, mine are white and much larger than a dot. Very curious that.
Also, this is @CrazyConure 's first year of having host plants for Monarchs and the predators take awhile to catch up. I had almost no predators in the first year (10 years ago). Now i make sure that the caterpillars have natural places to hide during the day when they mostly sleep and i have a much higher success rate in bringing caterpillars to full adulthood. The first year, when i hardly knew what i was doing, i had over 125 healthy flying Monarch's eclose in one day. That was quite a feat for my oh so small garden. I got the count by counting the empty chrysalises i found so there were probably more than 125
