Azaleas and Rhododendrons

Coveted for their spectacular blooms which come in a wide range of shapes and colors, Azaleas and Rhododendrons are members of the genus Rhododendron, one of the largest genera in the plant world which includes over 900 species and over 20,000 named hybrids. All are fascinating.

• These highly popular ornamental shrubs come in all sizes, ranging from dwarf, ground-hugging varieties which may reach 16 in. in 10 years (40 cm) to giant tree-like specimens as tall as 20 ft. or more (6 m). Both moisture and the length of the growing season will have a serious impact on their growth rate. Some Rhododendrons will experience a fast growth rate (2 ft. per or 60 cm) while others will slowly grow less than 0.5 in. per year (1 cm).

• Usually blooming in spring for about three weeks, their flowers range from the tiny and delicate blossoms of floriferous dwarf shrubs to the huge 'trusses' of tall growing hybrids and species. Some varieties bloom much earlier in the winter, while others will blossom in mid to late summer. One big splash of color in spring is great, but what if your garden were to show cheerful colors in winter or late summer? With some planning and plant hunting, you could enjoy these wonderful flowers almost all year long!

• Some Azaleas and Rhododendrons are deliciously fragrant.

• Many deciduous Rhododendrons or Azaleas feature a wonderful foliage adding glorious fall color to the landscape.

• In bloom or not, many evergreen Rhododendrons feature a handsome foliage and make outstanding garden plants year-round.

• Versatile, these ravishing shrubs can be grown in beds and borders, wall-side borders, city gardens, cottage gardens. Where space is tight, some cultivars can be grown in patio containers or small gardens. Others are ideal for growing on banks and slopes or as magnificent hedges or privacy screens.
