When you look at certain species of wildflower, you cannot help but think that their blooms look just like miniature bells. Some of these plants even have flowers that droop down in such a way that you may find yourself waiting for a breeze to blow to make the "bells" start ringing. Differences in the plants they emerge from, their colors and their size will allow you to identify these bell-shaped wildflowers.
Discern morning glories by their leaves and by the vines that they grow on. There are multiple species of morning glory, with some growing wild and others cultivated. The vines will snake their way up and around any structure that they are close to, including other bushes. The leaves have a heart shape and the flowers, which close at night and open in the morning, look like bells, with some types as wide as 8 inches. You will find that the many kinds of morning glories come in a wide array of shades, with pink, white, blue and purple often seen.
Distinguish bellflowers by their weak stem. The entire stem seems to lack strength and despite the fact that the flowers are small, the bellflower plant is prone to bending over. The flowers are typically blue or purple but sometimes may be white. They occur in clusters near the upper portions of these 1- to 2-foot-high perennials. Note that the leaves appear narrow and curled.
Identify bellworts by the manner in which the leaves grow on the stem and the yellow flowers. Bellworts can grow as tall as a foot and a half and while the bell-shaped flowers are usually yellow, they will occasionally be creamy white. The stems actually look as if someone threaded the leaves onto them. The leaves possess a lance shape and do not attach to the stems at their bases. Instead, they grow in such a way that the stem seems to pierce them about an inch from their base area.
Recognize bluebells by the bell-like flowers hanging down in clusters from a plant with large leaves. You may find large patches of bluebells growing in an area. These flowers, also known as cowslips, have flowers that are pinkish at first but gradually change to a purplish or bluish hue. They grow in clusters and become heavy enough to make the stem bend over under their weight.
