Perennials & Roses
What is a Perennial?
Perennials are herbaceous plants that die back to the ground each fall and return in the spring from their rootstock. When choosing perennials, it is important to select a variety of plants with different bloom times in order to have color in your garden from spring to fall.

Wonderful Selection To Choose From
Knock Out Roses
The Knock Out family of roses are easy to grow and do not require special care. They are the most disease resistant rose on the market with stunning flower power.
Fragrant and a great punch of color! Enjoy their generous bloom cycle (about every 5-6 weeks) until frost. No need to deadhead, they are self cleaning and winter hardy to USDA Zone 5 and very heat tolerant. If unpruned, the Knock Out will easily grow to be more than 3-4' tall. Once a year it is recommended to cut to about 12" above the ground in early spring (after the last hard frost) for maximum performance.
Also known as the Drift or Carpet Rose, these beauties prefer hot conditions and will also continue to bloom. Being disease resistant they are pretty easy to maintain and carry gorgeous clusters of flowers.
An ideal rose for both home gardeners and professional landscapers. They do not require spraying and are resistant to blights such as black spot and mildew. Plant height can vary between 1 - 5' or more. Shrub roses are very fragrant, attract birds and make great cut flowers. The cluster of blooms are accented by brilliant golden yellow stamens that sit over deep glossy dark green foliage with a burgundy edge.
Hybrid Tea Roses
The most popular variety of rose. Hybrid Teas are characterized by their large, high centered buds, classically formed blooms, and stiffly upright habitat. Long favored in a smaller garden in a formal setting.
The exquisitely shaped flowers continue to be the standard rose of the floral industry, due to the fact they're generally borne singly on long, strong stems. They offer a captivating fragrance and can grow to 5' tall and wide. A true beauty in a bouquet, but equally rewarding adorning your garden.
Climbers possess large flowers, similar to other garden roses that are typically held singly or in small groups. They have the ability to repeat bloom with the most heaviest bloom time being in the spring.
Throughout the season the bloom time will be scattered, however the rose itself will be of a finer quality and larger than those of the bush form. Climbing roses have endless uses. Find them on fences, walls, trellises and more. They bring a sense of charm to the garden and since they require very little pruning, they are always a customer favorite!
