Johnson’s Blue Vs Rozanne: Detailed Comparison
Although Johnson’s blue and Rozanne are quite similar, there are a few worth mentioning differences. We’re going to elaborate on them to help you decide which one to pick.
Color, Design, and Overall Appearance
Both Johnson’s Blue and Rozanne are unique and extraordinary. Having these in your garden would change the entire look of it.
Color-wise you won’t be able to make out much of a difference between them. However, Rozanne appears to be rounder with wider petals and more vibrant colors.
Johnson’s Blue’s petals are separately arranged and lack a lush look in them. But here’s the thing- they bloom in masses. And that ultimately makes your garden look magnificent.
You can make your Rozanne bloom densely as well. All you need to do is prune them a bit more frequently. That’ll help trigger its growth and result in consistent flowering.
Pruning is in fact quite vital for your overall garden health. A good pruner is important for making your job more efficient. Below I’ve mentioned some of the finest pruners available in the market.
Chances of Survival
Johnson’s Blue and Rozanne, both are hardy perennials. Perennial plants can live for more than three years and are capable of surviving adverse environments and weather. But, there’s a catch.
They might survive through all kinds of adversities, but their appearance might not stay the same.
Rozanne appears to be floppy and a little lifeless when it doesn’t get enough sunlight. It needs about 3 to 4 hours of direct sunlight to keep its fresh look intact.
So you need to be mindful about planting your Rozanne under direct sunlight.
On the contrary, that’s not the case with Johnson’s Blue. It can stay under shade for days and its beauty won’t seem to fade. It acts as the true hardy plant like it’s supposed to.
However, if your geraniums don’t receive sunlight at all, their leaves may turn white. So, it’s better to keep both Johnson’s Blue and Rozanne where direct sunlight is available.
This problem occurs due to a fungal infection. So just in case, your geraniums get infected, here are some fungicides you can use:
Care and Maintenance
There is a wrong conception regarding Geranium Johnson’s Blue and Rozanne. That is, they don’t need care and maintenance as they are perennial hardy plants.
Doesn’t matter what kind your plant is, perennial or biennial, you need to care for them to ensure they look lively all the time.
However, if you ask which one is easier to care for, we’d say Johnson’s Blue.
As we’ve said before, Rozanne may look a bit lifeless if it’s left uncared. They won’t die, but there are chances you may find them sprawled around.
Now if you’re a regular gardener, it surely won’t be a big problem for you. You just have to take care of them just like you do with your other plants.
Lack of regular maintenance causes most plants to become weak, stop flowering, produce small or immature fruits, and even die.
But these geraniums won’t even need too much attention. Just make sure they’re getting sunlight and the soil is dry or well-drained. Also, applying fertilizers from time to time would be enough to make them glow throughout all seasons.
On that note, it’s important that you’re using good quality fertilizers on your plants. Below I’ve recommended some well-known fertilizer brands that’ll work magic on your garden.
Frequently Asked Questions
Question: How do I ensure that my Rozanne is regularly flowering?
Answer: You can ensure that by pruning your Rozanne from time to time. Pruning regularly is important for both Johnson’s Blue and Rozanne. But it’s more important for Rozanne because it lacks consistency at flowering.
Question: Should I plant geraniums along with the other plants in my garden?
Answer: It’s better to use a separate area of your garden to plant geraniums like Johnson’s Blue and Rozanne. These plants spread around the area they’re planted and seem to spread quite aggressively. So it’s best to not plant other plants around geraniums and vice versa.
Question: When do I need to divide my Geranium Johnson’s Blue and Rozanne?
Answer: At around 5 years of your plant’s age, it’ll start producing fewer flowers. Then you may plan on dividing your geranium. It’s ideal to do it in springtime or early summer.
