Achillea 'Coronation Gold'Yes that's right. Some of my plants in the garden have the flop's. No it isn't a new disease or varietal weakness (that I know of). Some experts would say the plants are mature and need divided. However, these plants were only planted in the last two years. It is possible the plants have excess growth from over fertilization from compost. However, that has never been a problem before. Maybe it's global warming. I should contact Al Gore, he seems to be an expert on these things.
Nepeta 'Walkers Low'
Salvia nemorosa 'Coradonna'
I'm scratching my head trying to figure this one out and what my solution is to allow these plants to reach their full potential this summer. My current conclusion is it's varietal weakness and too much nitrogen, then followed with early warm weather in late march and cooler temps in April. On the Coronation Gold yarrows I'm going to deadhead after bloom on one of three plants and compare. I would hate to loose the spent blooms during the winter.
And alas: my first monarch visit, a male.
