Asclepias Tuberosa vs Curassavica
I am trying to attract some Monarch butterflies so I am planning on planting some Milkweed in my yard. I went online and bought some seeds for around 10 types of Milkweeds. I planted some A. Tuberosa and Curassavica in some jiffy pellets because they were the two types that I read don't require cold stratification.
I got very good germination. After a time I transferred them to a little bigger container, some deep pots that aren't much wider but are a lot deeper. The seedlings appear to be doing well but the A. Tuberosa seems to have a very abnormal growth habit, it doesn't grow vertical like the A. Curassavica. I also bought some A. Tuberosa from a local nursery and again, they seem to grow horizontal over vertical.
Is this normal? The A. Curassavica is growing very vertical and in about half the time are looking way larger than the A. Tuberosa that were grown about a month before. I have to say the A. Curassavica appear to have a very good vertical habit, they are looking very healthy and pretty against the A. Tuberosa where the plants are growing into each other and have almost half the height.
