You have seeds of which kind, the front or the back yard ? Seeds take long to germinate ? will see if there are plants at local nurseries next spring...I have Asclepias syriaca (common milkweed) in the front and incarnata (swamp) in the back. Common is big and invasive. Swamp is big but more delicate and ornamental. Both smell good and are loved by pollinators and monarchs. Aphids are common in late summer and can be removed with an artists' paintbrush. I have seeds.
