Question about AsclepiasTubersoa Butterfly Weed
I purchased two of these from an reputable online nursery, along with 2 'Ice Ballet' Milkweed.. The butterfly weed are showing no signs of life after being planted for two weeks, while the milkweed are about 6" tall with new growth. Are the butterfly weed much later blooming? Should I have some growth by now, but then my Greggii salvia I planted last year have not shown any new growth this spring either. Any advice?
