Does your family have a sunny Saturday afternoon to spare? Grab the kids and head to Boerner Botanical Gardens for a few hours of flower gazing. Admission is free, as is the following activity.

See if your family can find the following:

A heart-shaped flower. It's a Bleeding Heart. The stem hangs from its stem like a jewel.

A flower named Jack. It's a Jack in the Pulpit. The "Jack" is the club at the end of the stem, which traps and hides flies until the blossom is pollinated.

A flower with a fuzzy stem. It's a poppy, with cup-shaped blossoms. Some poppies have heads that measure 8 inches across.

A white flower with three leaves. It's a trillium, a wildflower that is native to Wisconsin. Look for clusters with three leaflets, three purple petals and three green sepals.

A flowering tree. It's a magnolia, with large, fury buds that open in late April and May. The magnolia's buds open later in the summer.

A yellow wildflower. It's a Marsh Marigold, which grows in wet areas. The early settlers cooked Marsh Marigold leaves and ate them like spinach, but the leaves are poisonous when eaten raw.

A flower that smells good. It may be a Hyacinth, which is the most fragrant spring bloom among Daffodils, Tulips and Narcissi.

A flower with three upright petals and three petals that hang down. It's an iris, the symbol of France, also called the Fleur de Lis.

A flower that attracts ants. It's a peony, named for the physician Paeon, the first to use roots for medicine.

A flower shaped like a cup. It's a Tulip, which means "turban" in Turkish. There are over 3,000 tulip bulbs planted in the Gardens.

Giant leaves. It's a Coltsfoot. Coltsfoot leaves and flowers are sometimes used in cough medicine.
