Many of the plants featured in this quiz are used in formal bedding schemes but they generally lack the intensity of color of the plants included in our bedding plant quiz. Nonetheless each plant has its merits and every one of the species here will be a particular favorite of many gardeners. Colors can be mixed together in an annual border without any problem but you will need to give some thought to the sizes of the respective plants. If you plant a row of sunflowers in front of your Portulacas you will see little of the Portulacas!
