Here’s the at-a-glance version for planning:

• Late Feb–March: Early bulbs (crocus, snowdrops)

• Late March–Early April: Magnolias, ornamental cherries

• Early–Late April: Redbuds, dogwoods, crabapples

• Mid-April–Early May: Tulips, daffodils

• Mid-May–Early June: Peonies, irises

Again, these shift with the weather every year.
