Yarrow gone mad!
I planted 2 types of yarrow in my wild/grassy type border. Cerise queen is behaving admirably, but the Parkers golden has gone crazy, sending runners galore, so I’ve made the decision to remove it all before it took over. I’ve left Cerise Queen to see how it fares as there are no runner coming off it. Great to have some more planting space, but a warning to others on the Parkers Golden variety... it’s a beast!!! I removed this lot from about a dozen plants I grew from seed last year!
The shorter prettier ones are lovely though and the bees love them all.
