These species just one survive, I founded one piece of root and plant in other pot, in this pot I put in different soil, this provide more air to roots, so have three years that I have this speciosa, they never grow like that, it’s so much beautiful, but do not looks that will bloom, what I do? However, I decided to “winter sow” a tray of seeds from a pod, that I put in my cold frame last January. For our annual milkweed containers, we use 10 or 12 inch pots. I do have tropical milkweed seeds so will do containers with them. Soil: There is a Milkweed variety for every landscape. Winter sowing worked really well for them. Monarch butterflies lay eggs on the plant in early spring. Narrow Leaf Milkweed (Seed) $5.00 Excl. Narrow leaf milkweed is a robust perennial native to many habitats and conditions across all of California. The Narrowleaf Milkweed provides food for monarch butterfly caterpillars and provides nectar for hummingbirds and nest building materials for other birds. Each fall, leave a couple inconveniently-seeded first year swamp plants in your garden and mark them. We were very surprised to see a bird take the chrysalis as we thought birds didn’t eat them. If so, what dilution? Are there precautions or suggestions you use when working with milkweed? the combination of moist soil and brisk wind is blowing the plants over and the roots are becoming exposed. (Thinking new seed from a different seed source might be in order).
Hi Lynne, sorry to hear you are having issues with the perennial milkweed varieties. Several stalks will emerge and your container will have a long bloom period in summer. The advantage to using second year plants? My dog should be fine?
