2 1/2 to 3 inch funnel-shaped flowers are white but sometimes pink with white strips or lavendure and slightly 5-lobed. The slender petioles are about one-half as long as the leaves. The large buds produce flowers with corollas that are usually white, although sometimes they are pale pink with spreading white stripes. However, deep within their throats the corollas are yellow. The flowers open during the morning and usually close at around noon, although they may remain open longer on cloudy days. The blooming period occurs intermittently during the summer for about 1-3 months. However, individual flowers last only a single day.

Flowers are replaced by broadly ovoid seed capsules a little less than ½ inch across. At maturity, these capsules split open to release their seeds (2-4 seeds per capsule). These seeds are dull brown to black, 3-angled (two flat sides and one rounded side), and rather irregular in shape; they are a little less than ¼ inch long.
