Yellow Asclepias
This yellow Asclepias has been blooming pretty must constantly all summer. It’s really quite amazing. Others bloomed for a while and then went to seed, which is what you sort of expect, but this one just keeps putting out new buds, which open into these lovely, pure, yellow flowers. As you can see, it also has seeds. This in on our back patio and it won’t make it through the winter (unless it’s exceptionally mild, of course). It’s only really hardy to USDA Zone 9. But growing it as an annual is really worth it. Highly recommended.
