Dinner Plate Dahlia

Some people automatically think of giant dinner plate-sized blooms at the mention of dahlias, but the Dahlia genus includes a huge diversity of plants and bloom size and flower forms.
Choose a variety that has the potential to produce mammoth blooms, like the 'Kevin Floodlight' dinner plate dahlia pictured here. Dahlias require full sun and plenty of fertilizer and water. If you wish, you can remove most of the buds to direct the plant's energy into producing only a few huge blooms. Dinner plate dahlias need a long time to mature and might require a head start indoors, north of hardiness zone 5.

Foxglove blooms are shaped like glove-like bells and come in various colors and unique patterns that make quite a statement when planted in groups.
These plants are biennial in zones 4-8, meaning they produce foliage their first year and flower the next.
