When planning to plant your bulbs remember to note heights and bloomtimes. Don't let yourself be disappointed by taller varieties obscuring the shorter ones, or being misled by the pictures on Spring collection advertisements or boxes. Group the bulbs that will bloom together with the colors you like and step their heights so each type is given its best position.
