The Morton Arboretum reopened to members only as part of a phased reopening on Monday, June 1. Members visiting during these next two weeks will be captivated by the landscape of abundant color and lush vegetation brought about by spring rains and plentiful sunshine. From June 15 onward, these same stunning views will be available to the general public, as visitors return to enjoy the tranquility and beauty of the Arboretum once more. To learn about the plans to reopen in June, please visit the Know Before You Go page. Stay connected with the Arboretum on FacebookTwitter, and Instagram and share pictures of the blooms you see using the hashtags #springblooms and #MortonArboretum.

  1. Chinese fringetree (Chionanthus retusus). Growing as a large shrub or multistemmed tree, this Asian species has fragrant, lacy white flowers in late May or early June and handsome peeling gray-brown bark. It is similar to the native American fringetree (Chionanthus virginicus). Both species will fit nicely beneath a power line without needing to be drastically pruned.
  2. Magnificent geranium (Geranium magnificum) and Forescate chives (Allium schoenoprasum 'Forescate') Ordinary chives, the same herb you might clip to add to a dip, will bloom with fluffy pale purple flowers if they aren’t cut back for the kitchen. Here, a cultivar of chives (at right) is combined with a handsome, hardy purple hybrid geranium, also called cranesbill.
  3. Philadelphia lily (Lilium philadelphicum). This rare Midwestern lily is native to moist black soil prairies and open woods. It is pollinated mainly by large butterflies such as swallowtails and monarchs.
  4. Beauty bush (Kolkwitzia amabilis). Exquisite bell-shaped pale pink flowers bloom abundantly in spring on the arching stems of this large shrub from China. Because it is unremarkable when not in bloom, it’s best sited at the back of a border in a larger yard.
  5. Caesar’s Brother Siberian iris (Iris sibirica ‘Caesar’s Brother’). Many garden plants that originally came from central Asia and Russia do well in Midwestern gardens because they evolved in a somewhat similar climate. Siberian irises have slender leaves and elegant flowers in shades of blue and white. They need good garden soil insun to part shade.
