The lily tribe is a big one, but there's no overlooking the Oriental varieties of these summer flowers. The most dramatic lilies, they bear large, star-shape flowers in shades of white, yellow, crimson, and pink. These blooms are ideal for cutting. And many are perfumed with a spicy scent detectable from yards away. Dwarf varieties stay about 1 foot tall; traditional types can grow more than 6 feet.
How to Grow Them: Oriental lilies grow best in a spot with full sun and moist but well-drained soil. Stake them to keep them standing straight and tall. They're hardy in Zones 5-9.
