Red Knockout | Shrub Tree Rose(Radrazz)


NOTE: New tree rose pictures are just an example of what it will look like after growing for few years, we will be shipping 2 year grafted tree roses that have formed stems from the graft.


Be the envy of your neighborhood with a Red Knock Out rose bush with full, disease-resistant flowers that bloom continuously and are always beautiful and healthy. Each cherry red, fully double flower blooms with a hardiness that ensures it is your knock-out rose for years to come. This unbelievable rose will bring joy to any grower for its non-stop blooming season. The bloom cycle produces rich cherry red, and hot pink blooms that will continue until the first hard frost. Furthermore, the plant is highly floriferous with blooms covering the whole plant and is easy to grow.

Open your door to the world of roses with this knockout rose variety. Beautiful buds soon open to delightful frilly petals that quickly fade to white for a beautiful contrast. It's the perfect rose for those looking for a few early-season blooms, or someone looking for a long-lasting rose that needs very little care. These are suitable to be grown in tropical, subtropical, and temperate regions
