The purple fountain is one of those ornamental grasses gardeners love having around their landscape.
The arcing spikes of feathery bristles and purplish flowers that prick up from the tips of the stems are so fascinating to watch.
However, there is a significant concern: Does purple fountain grass come back every year?
Well, it will die during the winter but come back to live within the spring season. Unfortunately, this Lazarus effect isn’t an every-year grace, even as a perennial plant.
I will explain more on that.
But how much do you know about purple fountain grass, though?
The table below will feed you with some valuable information.

Does Purple Fountain Grass Come Back Every Year?
Purple Fountain Grasses are hypersensitive to freezing temperatures.
Therefore, they barely make it through the freezing winter outdoors. It is like a dead stop for the plant.
They are most likely to grown as an annual plant.
However, they are hardy in USDA Plant Hardiness Zones 9 and can thrive regardless. That is because these zones witnesses mild winter or temperature do not drop significantly.
Some gardeners claim it can flourish in zones 7 and 8.
I’m not too sure of that one.
It will likely grow when given adequate weather protection in a turbulent winter.
But I am only confident with zone 9 that your Purple Fountain Grass will (without a shadow of a doubt) come back.
Anything outside these zones, your fountain grass will perish in icy winter and only grow back if you grow yours in a container and bring them inside.
Is Purple Fountain Grass Easy To Care For?
There was a time when I used to have a purple fountain and a couple of other ornamental grasses around my garden.
I didn’t remember doing much to have healthy growth and blooming.
That is why they are such a popular choice for many gardeners because they are carefree in the yard as long as they get enough sun.
However, most gardeners apply a balanced, slow-release fertilizer in spring and summer to boost growth and flowering.
It is a good idea. But Fountain grass can also thrive in poor soil. However, you do expect to get the same result.
Pruning is also vital and should be done after each flowering cycle.
The only drawback I can relate to is that purple fountain grasses are susceptible to pests like grasshoppers, mealybugs, and aphids.

Is Purple Fountain Grass toxic?
No, purple fountain grass isn’t toxic.
But does it mean it is edible?
Of course not!
It hasn’t been proven that purple fountain grass has chemical toxins in its walls or tissues, but when ingested, it can cause mild gastrointestinal discomfort.
While they are categorized among poisonous plants, they can harm you.
And based on your climate, if you are skeptical about whether your purple fountain grass will come back, here are a few tips that might help:
First is mulching.
If it frightens you that frost might kill your fountain grass, you integrate a thick mulch around its base right before the first frost.
This insulates the root and helps heighten the chances of survival
You can also grow them in containers and bring them indoors during the colder months. However, this technique works best for container gardening.
