Camellia

While most garden plants spend winter taking a well-earned rest, camellias are just getting warmed up. These popular evergreens flower in the fall, winter or early spring. They are great for landscaping and produce beautiful rose-shaped blooms.
Camellias have been cultivated for years in the Far East, their native region. Today, there are over 250 species and more than 3,000 varieties.

Forsythia

When this shrub blooms, you know warmer weather is on the way. Forsythia is one of the first plants to flower in spring, when its golden bell-shaped blossoms are a welcome sight.
Once the shrubs have bloomed, and if they're more than 3 years old, get out the pruning shears and cut the very oldest branches down near the ground in order to encourage new shoots for next year.

Lilacs

As spring gets into full swing, if you detect a sweet fragrance floating on the breeze, chances are it's a lilac.
This beauty originally comes from southeastern Europe and eastern Asia. Its distinctive scent and lovely blooms helped it become one of the most popular flowering shrubs in North America.
With an array of sizes to choose from, it's easy to bring the delightful fragrance home. But it does require a little patience - lilacs take 4 to 5 years to produce their first flowers. Once established, however, careful pruning of spent blooms and stray branches right after flowering will keep the scent-sational show going for years to come.

Botanical Name: Syringa vulgaris.
Hardiness: Zones 3 to 8.
Bloom Time: Late spring to midsummer.

Growing Advice: Dig a hold the same depth as the root ball, but wider. Loosen roots of pot-bound shrubs before planting.
Prize Picks: Ludwig Spaeth blooms a bit later, with magnificent purple flowers, a heady scent, and handsome, dark-green foliage. Syringa patula Miss Kim is slightly larger with lilac-blue blooms. Both are hardy and resistant to disease.
