The Double KnockoutŪ roses are produced from the same cross that horticulturists used to create the Knock OutŪ roses. The newest variety to add to the family, Double KnockoutŪ roses promise to upgrade their predecessor with more robust and better looking petals and disease resistant genes.
The Double KnockoutŪ roses are very adaptable. The soil conditions that they require are not even rigid, though they are intended for US Hardiness Zones 4 to 9. These species were produced to withstand long periods of drought, rain, extreme heat, and extreme cold. They can be planted anywhere where perennials, annuals, and low shrubs are needed. Reaching up to 4 feet in height and width, the Double KnockoutŪ roses can be useful hedges and improvised fences. They can be wonderful features to a patio or a deck since they are able to survive partial and even full sunlight. Gardeners can even choose to grow them in containers and put them in shade. To make a statement with the Double KnockoutŪ roses, be sure to plant in groups of three or more.
The amazing improvements that horticulturalists are proud of the Double KnockoutŪ roses include the conservation of the attractiveness of the original Knock OutŪ roses combined with enhanced resistance to pests and diseases. The Double KnockoutŪ roses produce thicker and more abundant pink or cherry red large flowers which have the longest blooming period starting in late May until early fall. Up to five flowers may be present per cluster, giving up to twenty five blooms per branch. The leaves are deep mossy green with blue and maroon highlights. In winter, the foliage starts at dark burgundy gradually lightening to an orangey-red, giving the Double KnockoutŪ roses their distinct glazed appearance. They even have the slightly spicy fragrance of the light tea rose, providing your garden with the scent of a natural spa. Another improvement given to the Double KnockoutŪ roses is better pest and disease resistance. Control methods for mildew, black spot, rust, fungi, and insects like leaf hoppers will no longer be a problem.
As an added bonus, Double KnockoutŪ roses are relatively low-maintenance giving vigorous vegetation and generous blooms that will last for almost two seasons. Pruning is not even a requirement in the first two to three years of growing these species. Only done to activate growth and blooming, pruning the roses back a little during early spring should be made at an angle and not directly across. When doing so, make sure to cut thin canes coming up from the ground and to remove the dead or diseased ones. Those planning to keep the roses smaller than their mature size should prune it back in the late summer or early fall.
For a splash of color and added fragrance to a garden that is green throughout the year, roses are still the premier choice. Of all varieties of roses, the Double KnockoutŪ roses will undoubtedly knock-out everyone else for their stunning flowers and disease-resistant genes. Why not opt for the best there is?
