Rosemary roses were first bred in 1954 in the Netherlands by De Ruiter Innovations. The De Ruiter family has several generations of rose breeders and has been active since the early 1920’s in the field of rose hybridization. The rose Rosemary was created by crossing the Gruss an Teplitz rose with a generic floribunda seedling. The result is a fabulous deep pink or light red rose.
The rose Rosemary will produce blooms that are very typical for a floribunda rose, averaging about 3 inches or in diameter. The blooms will be very full, having around 25 or more petals each, and they will have a fairly strong fragrance that you are sure to love. The plant itself will grow upwards of about 3 feet tall at full maturity, with a width of around 2 feet across. This great rose will do well in zones 6 and warmer.
Growing the rose Rosemary in your garden at home is not all that complicated and if you have had any prior experience growing roses, then you should not find this variety to be all that complicated. The biggest decision you will make in the life of your roses is where in the garden you choose to grow them. Roses will need a lot of sun light if you want them to perform well and this variety is no exception. Try to select a location that gets no less than 6 to 8 hours a day of direct sun light. If you can provide more then that is even better.
You also will want to grow your Rosemary roses in soil that drains very well. This is usually a no brainer for most experienced growers, but you might be surprised at how many newer growers overlook this point. This is however a very easy thing to overcome. If you take a trip to the local garden center, you will find a wide variety of growing soils to choose from, many of which will be designed specifically for growing roses. Choose the one you prefer and use that. Your rose Rosemary will thank you for it.
Getting your rose Rosemary into the ground is not a difficult task and most growers can get the job done very easily with just a few basic hand tools. How you go about planting your roses depends a little bit on how you purchased them. If you bought one from a local nursery, then chances are it was already planted in a container for you and ready to bloom. These are the easiest roses to plant. Dig your hole at least twice the diameter of the container and equally as deep. This will give you plenty of room around the roots for your soil mix while keeping the bud union at its original depth.
If you bought your Rosemary roses online, then they may have shipped them to you as bareroot plants, which is not uncommon. You should first soak the roots of these overnight in a bucket of room temperature water, prior to planting day. Then dig your hole as wide as the longest roots on the plant and deep enough to allow you to set the plant on top of a mound of soil while keeping the bud union no more than an inch or so below the surface of the soil.
Once you have your rose Rosemary set in place on top of the mound, spread the roots out in all directions and then back fill the hole about halfway to start, using your soil mix. Take the garden hose and water the loose soil heavily until it flows around the roots like mud, then you can go ahead and finish filling the hole. Give the soil one more heavy watering and be sure to top off any final settling that might occur. Do not tamp down the soil. This method should make sure that no air pockets have formed around the roots of the plant.
Taking care of the rose Rosemary is pretty straight forward. You will need to make sure that you are providing your roses with enough water and nutrients, while being careful not to overdo it. For most climates, this amounts to about one deep watering per week. If you live in a hot or dry climate then you should check on your roses every 4 to 5 days.
You also should consider giving your Rosemary roses a dose of a granular all-purpose fertilizer in the early spring when the leaves begin to open up. This will go a long way towards giving your roses a good head start to the season. Like most floribunda roses, this one is also a repeat bloomer, which means it will benefit nicely from a few additional feedings over the course of the growing season. I will usually give my roses their second feeding immediately following their first big bloom, and then a third feeding sometime around the middle of the summer to promote late season blooms. Your rose Rosemary should do nicely on this schedule as well.
You should prune your rose Rosemary in the very early spring when the weather starts to warm but before the leaves begin to open up. This makes pruning so much easier. Start by removing all the dead and discolored wood from the plant and set your cuttings aside. Next, prune back any overlapping lateral canes from the plant as these could eventually compete for sun light once the leaves fully open. Lastly, give the remaining canes a cut back by about one third of their current height to promote new growth.
This is the best time to clean up around the base of your Rosemary roses and get rid of all the dead leaves and debris that may have collected there from the previous growing season. Throw all of this dead material away in the trash, along with your cuttings. Never let dead matter lay around your roses as it can quickly turn into a breeding ground for various pests and diseases. Finish up your pruning by giving your rose Rosemary a fresh new layer of mulch to start off the growing season.
