What’s in Bloom

Herbaceous peonies in southeast Michigan bloom from approximately Memorial Day to mid-June, depending on the weather.  Until then, you can still visit other areas of the Arb to see blooming plants spring, summer, and fall.

It’s been a great run, but the peony garden is nearing the end of its bloom. The flowers are starting to drop petals quickly now and the plants are starting to droop. It’s all part of the experience, we never quite know how long we will have with these lovely friends, we just enjoy the bloom while it’s here.

If you were waiting for the perfect weekend to come to see the peonies at Nichols Arboretum, this is it! We still have about 20% of our plants waiting to bloom, but they are opening very quickly in the heat.

The chilly weather we’ve had recently seems to have slowed things just a little – there are lots of buds getting ready to open, but not much flowering yet, beyond our tree peonies. While it’s likely we will have some flowers this coming weekend, our guessers are guessing peak bloom will hit around the weekend of June 3rd.

We are starting to see some nice, large buds on a few plants, and guessers are guessing which plant will be the first to bloom this year. We are still weeks away from the mass bloom.

Despite the cold dreary weather, the peonies are continuing their upward growth.  No blooms yet, but many of the bushes have buds on them.

Our peonies have started to emerge and grow tall as they prepare for their mass bloom. At this point, we just wait patiently as nature does its thing.
