At the east end of the Commons several roads intersect in an area known as the tuning fork, forming three triangles of land in the middle of the streets.
The first one is at the intersection of Aurora St. and E. State St. In early spring the triangle is a riot of color with yellow daffodils, and a succession of four varieties each of red and yellow tulips in the center and purple grape hyacinths on the edges, followed by Pixie Bright Asiatic Lilies, a low growing border variety, around the edges. The triangle has been planted for several years with yellow Marigolds—varieties Marvel and Antigua, plus perennials Oenothera and Leopard's Bane by the sidewalk, Daylilies, Salvia and Nepeta in the center, providing a succession of bloom with a blue, purple and yellow palette of color.
With the construction of the adjacent seven-story City Centre, the Beautification Program decided it was time for a complete re-design and re-plant of the Aurora Triangle. This was completed in fall of 2019 and includes mostly native perennials. Some annuals may be added for color until the perennials fill in. Watch for spring 2020 blooms!
The triangle of land bound by Green St. and Seneca Way is known locally as Sign Triangle due to the large number of traffic signs on posts it houses. The blooming here starts in April with four varieties of red Tulips, blooming in succession. The edges of the triangle also bloom red later in summer with low growing Crimson Pixie Asiatic Lilies in full bloom. As the summer moves forward, self-seeding orange blooming California Poppies take over the edges of the triangle, while Benary’s Giant Zinnias form a colorful center. Seven Arctic Fire Redtwig Dogwood shrubs are almost hidden in the center of the triangle. Four Hardy Hibiscus bushes next to the sidewalk boast giant saucer flowers in pink and red. A narrow strip between the sidewalk and E. State St. features a variety of Red Velour Petunias with American Marigold varieties interspersed with the tall self-seeding light purple Verbena bonariensis and Cleome hassleriana (Spider Flower) in shades of pink. At the point of the triangle, where the one-way traffic approaches on both sides, tall spires of Allium bulbs are surrounded by red Zinnias, Zahara Double Fire.
In keeping with our native plants focus, native grasses and perennials were added to sign Triangle in fall of 2019.
The largest of the three triangles is bordered by E. State St., Seneca St. and Seneca Way. This triangle is anchored by three large Zelkova serrata (Japanese Zelkova) trees, creating a dry and shady landscape. Snowdrops (Galanthus varieties) in large drifts surround an abstract metal sculpture and bloom here early in the spring, interspersed with early blooming perennial Hellebores. These are followed by masses and masses of daffodils, and later, by red tulips in April and tall Lilies in the summer. Starting in late May, annual flowers and foliage plants hide the fading bulbs. The shady areas are planted with a variety of plants, including Hostas, Hellebores, Pulmonia, Ligularia and others. A small planting of Aster novae-angliae ‘Purple Dome’ and Hardy Chrysanthemums leads to the sunny point of the triangle, filled with Rudbeckia hirta ‘Indian Summer’ and ‘Irish Spring’, surrounded by Zinnia Profusion Double Fire.
Between the sidewalk and E. State St. is a strip that is sunny at the east end and shady at the west end. A new mixed planting of shrubs, perennials and annuals includes Purple Beautyberry (Callicarpa Americana), Daylily, Salvia, Echinacea Cheyenne Spirit in the sunny part, Hellebores, Pulmonaria and others in the shady area.
In addition, the north point of the triangle was planted in 2019 with three Myrica pennsylvanica (Northern Bayberry) and one Physocarpus (Ninebark) shrub. More asters and grasses were added as well.
