It forms clusters of white blooms, but you can find cultivars of different bloom colors. This perennial has served as an herb to staunch the blood flow before this present time.
Its herbal function is the reason why it is scientifically called Achillea. Currently, most gardeners are primarily attracted to the beautiful nature and low maintenance of yarrow than its medicinal function.

Even though they are called perennial flowers, daylilies only bloom for a day. However, they can bloom in concession, which means each bloom comes after the other has gone, so you still stand a chance of enjoying them all summer.
The best time to plant them is in spring or fall when the soil is softer and needs full sun to partial shade for proper growth.

Buddleja genus has several species that are perennials or deciduous shrubs, most of which die back to ground level in colder temperate before sprouting again in spring.

Meanwhile, the butterfly bush significantly flowers from June to September, and most of its varieties are giant at about 6 to 8 feet, but some species are more compact.

Essential Care Tips for Perennial Flowers that Bloom from Spring to Fall
If you go through our list carefully, you'll discover that all our top 25 full sun perennial flowers are hardy plants or close to being hardy at the very least; hence, they are low-maintenance plants that can do without the attention. They are drought and heat-resistant plants, and while some are resistant to deer and other animals, others attract deer.
But most importantly, considering our key focus in the article, every one of these flowering perennials prefers full sun, which is why they are sun-loving plants.
However, some can tolerate partial shade, but the condition that will yield the best result is full sun. Without further ado, we'll briefly highlight the critical growing tips for perennial flowers that bloom from spring to fall.
Natural Habitat/Lighting Tips
Given that most perennials have their natural habitat in the South African wild and others within the dry, sunny deserts of Northern America, it shows that they can tolerate the hot weather conditions of full sun from their native location or jungle.
In other words, if you want them to thrive in your homes or gardens, or you want to maintain their healthy nature, then you must imitate their natural jungle conditions by growing them in a location that gets full sun or partial shade (depending on your climate).
But if you want to position them in a partial shade area, you must ensure you bring them out to receive adequate sunlight for at least 6 to 8 hours.
Soil Care Tips
Perennial flowers can survive in almost every soil, whether loamy, sandy, clay, etc., depending on the plant, but it must be well-drained.
However, you must ensure the ground is a little moist, especially immediately after planting, as this will ensure the plant grows healthier.
Watering Care Tips
Perennial flowers are drought-resistant and, therefore, do not necessarily require water for sustenance, significantly if grown in the ground.
In their natural jungle, wild, or desert, they survive long periods without water, except for rare periods where they experience rainfall. Therefore, if you must water them, you must do so only sparingly.
Meanwhile, the best time to water these perennials is once after planting to enhance their growth. However, after they are established, you must reduce your watering routine.
In a prolonged drought season, within April or May, ensure water only moderately and use pots with well-draining holes that let the water dry out quickly and prevent waterlogging.
Temperature & Humidity Tips
Perennial flowers are famous for their hardiness in their natural environment, so they can tolerate extreme temperatures when the soil permits too much rain or snowmelt to drain out. However, the best humidity well-suited to your perennial flowers is in a dry place with enough air circulation.
As far as temperature is concerned, perennial flowers require temperatures of about 40 to 70 degrees Fahrenheit. In most situations, they will need cold temperate to help their roots to sprout well.
Therefore, whenever you notice some chill in the atmosphere in the fall, it is the perfect planting period for your perennial flowers to make them bloom from spring to fall.
Perennial flowers do not require too many nutrients for sustenance. After all, out in the wild, they hardly see any source of nutrients, yet, survive, regardless. However, in the spring, you can fertilize sparingly using a low-nitrogen fertilizer (6-10-10) around the plants to assist their healthy growth.
But you must not fertilize heavily, whether with nitrogen fertilizer or any other nutrient fertilizer, as instead of producing flowers, these perennials will only encourage foliage. Another ideal fertilizer for these sun-loving perennials is bone meal.
Potting & Repotting
Generally, growing perennial flowers in vases is not a standard method; however, there's nothing wrong with planting them in huge pots. But while doing that, it must be with a loose, soil-free potting mix and leave the top of the rhizomes exposed.
In pots, perennial flowers do not require overwatering. Meanwhile, in colder regions or frost seasons, you must move the pots to a sheltered area for the winter to sustain their health. Transplanting and dividing in such conditions need to be done more often (yearly) than those grown in landscapes.
Deadheading is cutting the spent blooms off your plants to make them appear neat and better. It also stops them from setting seeds to prevent a mess of perennial flowering seedlings from popping up in your landscape.
Fortunately, most perennials react to deadheading by producing more flowers. Some examples of these rebloomers are the likes of threadleaf coreopsis, delphinium species, phlox, yarrow, and veronica, amongst others.
One of the fascinating features of perennial flowers is that they get bigger and better every year, including those that bloom from spring to fall. Yet, most of them will begin to crowd themselves out if they grow too large.
You must ensure they perform well by uprooting them from the ground and dividing them into fragments every three to four years. Early spring is the best time to divide most of these flowering perennials.
But there are a few which do not require deadheading in spring, including Bearded Iris and Hosta, as they can only be divided in summer.
