Much of the charm of the Conservatory’s Abby Aldrich Rockefeller Garden display comes from a glorious assortment of upright annuals. These make tall, statuesque, and often bold additions to any seasonal border. But while we often associate height in both perennial and annual borders with spires that guide your eyes upward—and there are certainly plenty of spires in this Groundbreakers display—what delighted me was the variety of other forms that gave height to the border.
One striking example was the monster-sized umbels of false Queen Anne’s lace, Ammi visnaga ‘Green Mist’. This opulent annual sports large Queen Anne’s lace flowers above ferny foliage. It grows to four feet tall and will create an impressive show whether placed in the middle or back of an annual border. It attracts beneficial insects into your garden and also makes a spectacular cut flower.
