How are the heights measured?

All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.

What is a gallon container?

Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.

How does the delivery process work?

All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!

Why are some states excluded from shipping?

The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.

The Double Pink Knockout Rose is most commonly used as a beautiful ornamental shrub or accent plant. Large pink roses lie on the green leaves, which attract the eye with ease due to their glossy appearance. Unlike the regular rose or even the original Knockout Rose series, created by rose breeder William Radler, Double Knockout Roses need even less management, meddling, and pruning. In exchange, they offer you more flowers, each with more petals.

Rich textures and colors adorn your shrub, and the passer-by will invariably pause to enjoy the rose-tinted fragrances wafting from your yard. The trouble-free Double Knockout Rose also has less problems with mildews and cankers, which is an issue with the regular pink rose.

Growing Double Pink Knockout Roses

You can anticipate moderately fast-growth from your Double Knockout Rose. Growers list the expected height of the shrub as between 3 to 4 feet tall, though gardeners who never prune can expect a 7 foot tall shrub. Since the Double Knockout Rose can gain between 2 and 3 feet of new growth a year, we here at The Tree Center suggest pruning back the Double Knockout Rose to one foot in height each season. Though this may seem like a lot, it will encourage new, healthier growth.

The Double Pink Knockout Rose is one of the most popular flowering plants, and there are many reasons why. First and foremost, the Double Knockout series is amazingly resilient. Disease resistant, drought tolerant, and soil adaptable qualities abound in the Double Knockout Rose series, making it the ideal fit for poor growing conditions.


Double Pink Knockout Roses grow well in USDA Hardiness Zones 5 through 10. They prefer well-drained soil that is slightly acidic. To ensure the best growth, have your soil tested for pH and water absorbency.


Beauty is next up in the list of positive attributes of the Double Knockout Rose. The rose has long been loved by gardeners, whose stunning beauty, captured in each flower, has inspired artists and scientists, writers and poets, engineers and mathematicians. The Double Knockout Rose, though, improves upon the qualities that attract the eye to the rose. Whereas the regular rose has only 7 to 12 petals, the new, richer blooms of the Double Knockout Rose can have as many as 24 petals. These doubled-up petals also appear more often, creating more flowers, which then can be cut to use in décor around the home.

Care and Maintenance

Roses, which have long been lauded for their beauty, are frequently despised for the amount of effort required for so little reward. Even Shakespeare noted this in his sonnets. The Double Knockout Rose series, however, seeks to dispel this problem. Some basic maintenance is all that is really needed in order to enjoy year after year of vivacious pink blooms.

Although the Double Pink Knockout Rose is a better version of the regular rose with increased disease resistance and blooming from the original Knockout series, it still requires mild pruning and maintenance, as do most flowering ornamentals. The benefit is that instead of pruning your rose multiple times throughout the year, the Double Knockout Rose only requires one pruning in early spring. Cut back your rose tree to about 12 inches tall. Heavy fast-growth will mean your rose will be back up to its normal height in just a few short months!

Planting Location

When planting your Double Pink Knockout Rose, find a location in the full sun, where the rose will grow best. Sunny shade can also work, but check to be sure your rose will receive between 4 and 6 hours of sunlight daily. After you’ve found the right location, dig a hole. The hole should be twice as wide as the rose’s root ball, and only just as deep. It is best if the root ball extends from the soil up to one inch. This will enable the rose to settle over time. Applying a 3-inch layer of mulch and fertilizer after planting can also be incorporated into your planting procedure.
