Roses have a long and colorful history. They have been symbols of love, beauty, war, and politics and have been used as confetti at celebrations, for medicinal purposes, and as a source of perfume. It wasn't until the late eighteenth century that cultivated roses were introduced into Europe from China. Most modern-day roses can be traced back to this ancestry. These introductions were repeat bloomers, making them unusual and of great interest to hybridizers, setting the stage for breeding work with native roses to select for hardiness and a long bloom season. Many of these early efforts by plant breeders are of great interest to today's gardeners.
Roses need to be grown in full sun. They like to be in soil that is well-amended with organic matter and has good soil drainage. A raised flower bed with additional compost is a great place for a rose. Starting with healthy soil will prevent you from needing to fertilize much later on. Newly-planted roses will appreciate watering around twice a week throughout the first growing season, and a 2 to 3-inch layer of mulch helps quite a bit. A large variety of roses can be grown in Central Texas but the knockout is one of the favorites since they are resistant to all rose diseases and do not require any deadheading to keep them blooming all season long.
