• Daffodils of any variety make a vibrant addition to the garden.Jupiterimages/Photos.com/Getty Images
  
  Enhance the garden with a variety of plants. Shrubs, perennials and bulbs come in a wide range of shapes, sizes and bloom colors to create a combination of texture, height and foliage in a landscape. They include versatile plants that tolerate a wide range of growing conditions, including drought and heat in those less-than-ideal climates. Here are three examples.
  
  

Daffodil

• The Avalanche daffodil (Narcissus 'Avalanche') is a tazetta-type daffodil that has a clumping growth habit and moderate growth rate. It grows 1 to 3 feet tall, making it an ideal bulb to grow in garden beds and borders. The Avalanche features a cluster of 10 to 20 tiny, fragrant flowers that create "an entire bouquet on one stem," according to Fine Gardening. Avalanche flowers have white petals and pale yellow cups; the flowers also have a musky, sweet fragrance. Avalanche daffodils are both frost- and deer-tolerant. They grow best in full sun to part shade and well-drained soil in USDA Plant Hardiness Zones 6 to 9.
  
  

Barberry

• Barberry (Berberis x stenophylla 'Corallina Compacta') is a broadleaf, evergreen, dwarf barberry cultivar. It has a mounded, low-growing form that can reach 1 foot tall and wide. It features clusters of spring-blooming flowers that are yellow to orange. The flowers on barberry emerge from red buds and "give way to globose, dark blue fruits," according to Missouri Botanical Garden. Barberry grows best in full sun, although it tolerates light shade, and well-drained, soil. It withstands drought, ideal for garden climates that are dry, but is intolerant of wet or poorly drained soils. Grow barberry in USDA Plant Hardiness Zones 6 to 9.
  
  

Hellebore

• Hellebore (Helleborus orientalis) is an herbaceous perennial plant that has a clumping form and grows up to 1½ feet tall and wide. It features cup-shaped, nodding flowers that grow 3 to 4 inches wide and appear in clusters of one to four. Hellebore flower colors vary from white to light rose to pink. The 8- to 16-inch-wide, glossy foliage on hellebore is dark green and "evergreen in warm climates but deciduous in extremely cold winters," according to Missouri Botanical Garden. It grows best in full shade and well-drained, humus-rich soil. Grow hellebore in USDA Plant Hardiness Zones 4 to 9.
