The Common Milkweed (Asclepias syriaca - in my yard has finally broken ground today. In the past three
years I have had milkweed above ground no later than April 3. That makes the emergence over three weeks late compared to the other three years that I have
data on. Yarrow is late as well however I have noticed a number of other plants
that seem to be close to normal in their timing...unfortunately I only have
solid documentation on the milkweed and yarrow. I wonder to what extent the
first real winter in the northern ranges in three years is effecting the
northward migration. We will have to watch and see.
