- Frequently Asked Questions
What Are Perennial Flowers?
Perennial as a word can be loosely interpreted to mean "through the years." This is to say that any flower that can survive for more than 2 growing seasons can be classified as a perennial flower.
What else can a plant be if it isn't perennial?
Plants can be classified into annuals, biennials and perennials. The annuals and biennials plants are short-lived, bearing a life span of a year and 2 years, respectively.
However, one crucial detail that you should know is that every perennial flower is not the same. They have varying life spans.
While some stay around for decades, others are the exact opposite; they survive for a couple of years, and some last for only 3 years before completely dying out.
Perennial Flowers That Bloom All Summer
We have compiled, just for you, a list of 27 recommended perennial flowers that are non-problematic, excellent pollinators and beautifying agents.
1. False Indigo (Baptisia)
One advantage of this plant is that they are typically pest and disease free. This means that they are highly resistant to the attack of pests and plant diseases due to how sturdy they are built.
One year after the seed must have been planted, your gardens will be graced with lupine-like flowers in beautiful shades of blue, purple and green. Then in the next few decades, you would have recorded a growth level of about 4ft in height with the plant filling out like a shrub.
The Baptisia requires full sun for it to grow well. Its bloom period is usually late Spring and sustains till early Summer.
Phlox also has a distinct feature: the strong, pleasant scent it releases. This feature is synonymous with both the low growers and the tall ones.
As soon as the Spring season begins, you will discover the ones categorized as low-growing Phlox begin to bloom as a ground cover. The plants that are as tall as 3 to 5ft are called the tall Phlox.
They pop during Summer and establish a colorful backdrop for the low growers. The Phlox would thrive under shade but would fare better when planted in a place where they can get ample sunlight.
Bloom period? Spring all through to the Summer season.
3. Butterfly Bush (Summer Lilacs)
Do you know why they are called Butterfly Bush? Dozens of butterflies are usually drawn to the blossoms on its shrubs all through Summer and Fall.

Lastly, endeavor to have them exposed to partial sun and enjoy their bloom season all through Summer to Fall.
5. Sedum (Stonecrop)
It's almost impossible to see this plant and not fall in love with it. It is the absolute favorite of gardeners and pollinators alike.

The plant is extremely versatile and hardy, easy to plant and stays resistant to pests and diseases.

How To Grow And Care For Perennial Flowers
Having your flowers grown right and caring for them timely and adequately are some factors that guarantee a long-lasting plant.
Caring for and maintaining your plants can be very demanding, time-consuming and sometimes complicated, making it difficult for many people to keep up with.
But, we have compiled some simple care tips formulated below by infusing some important horticultural ideals and gardening experience amassed through the years.
These care tips are very understandable and will leave your flowers looking radiant and attaining their entire life span if followed to the letter.
Before choosing a planting site for your plant, you must first put into cognizance the plant's needs and ascertain if they will be obtainable at the intended location.
Things like temperature, air availability, soil, light etc., should all be factored in the site decision-making process.
We really cannot emphasize the importance of suitable soil enough. Bad or unfit soil cannot produce healthy-looking plants; it is highly impossible.
Preferred soil for most perennials is a well-drained and fertile one which is usually one with a Ph level of 6 or 7.0.
For a better result and since your plants cannot get enough nutrients, include some necessary organic matter like compost, leaf mold, manure and the like. What this organic matter do when added is improve the overall quality of the soil.
Add some layers of mulch to reduce the frequency in which you will have to weed and keep the temperature of the soil in a steady cool state.
You need to know the kind of plant you intend to plant, its needs, the right soil type, and its growth capacity.
The needs of the plant would determine if you are to have them planted under full/partial sun or shade; knowing the soil type it requires would make you avoid waterlogged soil when, in actual fact, it prefers a well-drained one and its overall growth capacity at maturity would help you in strategically positioning them for planting.
We must have read about some perennials that can tolerate a lack of water, but the plants can only be equipped with that ability after they have been appropriately established.
Timely watering plants is one way to establish them in the ground. Have the plants soaked at once and periodically checked, so they do not dry out.
The key is not to water the plants frequently but timely and strategically. Less frequent but deep watering will promote deep rooting of the perennial.
Over-application of fertilizer is not advised for perennials.
How, then, do you know the right amount of fertilizer needed?
To ascertain the amount of fertilizer your plant needs, a soil test should be carried out. The truth is that the bulk of perennials does not require much fertilizer.
The danger of applying too much fertilizer to them is a highly soft growth with the plant, producing much fewer flowers than it ought to.
The best is to do a soil test to determine the exact amount of fertilizer to use.
Perennials are best planted close to a fence. This is suggested because the fence would eventually act as a support for the plant when they begin to grow.
Aside from that, we still have other reasons why plants need support. Anything can make them flop over, cases where they grow so tall and can no longer balance on their weight or when they have been beaten by rain and forced to be bent over.
Support in the form of a stake should be put in place to keep them in an upright position.
For best results, have the staking done before Spring so the plants can grow through and around it.
