Asiatic Lilies bloom first. The flowers face upright and the plants are usually shorter than the other lilies, about 2 ft. tall in bloom or sometimes taller. Trumpet Lilies bloom next, about a month later than the Asiatic types. Plants are tall and royal looking, often 4 to 6 ft. You can't have too many of these.
Oriental Lilies are the last to bloom in summer.
Most of these are delightfully scented, all are gorgeous, and they grow about 3 to 4 ft. tall. Lilies get better each year. They increase the size of their bulbs, making smaller ones and spreading outward. Some lilies form tiny bulblets along their stems which they hurl off in late summer and which will form small lily plants next summer. Lilies also are fantastic cut flowers.
