Yes, there are at least two types of Milkweed, the one in the U.S. that most everyone knows as necessary for the survival of Monarchs, simply called Milkweed, Asclepias syriaca (Wikipedia link) or often called “Common Milkweed.” It must go dormant in the winter months. While the Tropical Milkweed, Asclepias curassavica (Wikipedia link) lives year around in tropical climates where there is always sunshine and above freezing temperatures. It is sometimes also called “Bloodflower” or “Mexican butterfly weed.” In Costa Rican Spanish, Tropical Milkweed (Asclepias curassavica) is most commonly known as “algodoncillo tropical”. It can also be referred to as “viborana” in some areas. See many more photos on iNaturalist Costa Rica.
I’ve added some to my garden this year to see which butterflies will choose it over the most popular Porter Weed (“rabo de toro” in CR Spanish which is “bull’s tail” OR “cola de alcarán” in the Caribe which is “scorpion’s tail”). Or maybe I will compare to my other two big attractors: Zinnias (“mal de ojo”) and Lantanas (“cinco negritos” or “soterrey”). Here’s five photos of my newly planted “babies” which have already attracted a tiny Metalmark . . . 🙂
