A collage of some of the prettiest summer flowers.

For some, the temperatures already arrived but for many summers is just around the corner. And unlike Spring, Summer flowers make the difference in bright weather versus wet April showers. However, plant the wrong ones, and many homeowners are going to be disappointed with weak growth or plants that fizzle in the highest heat around July and August.

So it’s important to understand which plants will produce the best results through the summer, during the heat climb, the peak, and then the eventual cooling that comes lower the later days of August and early September. Here’s the comprehensive list every homeowner should consider if summer flowers are on the to-do list this year for brightening up the front and backyards.

Beardtongue (Penstemon)

A beautiful cluster of beardtongue flowers.

The plant has a very weird name, almost like a pirate’s favorite plant, but this summer flower is a mix of challenges more akin to an aristocrat. It blooms fast and with lots of space, significant blooms, and a noticeable cone-shaped flower. However, it can’t be allowed to clump up or the crowding affects the health of the plant. Long story short, Beardtongue is a fussy, temperamental plant, but the flowers still make it attractive to grow anyways.

The Blanket Flower (Gaillardia)

A close inspection of a blanket flower.

Technically known as a perennial plant, and Gaillardia by its correct name, the Blanket Flower is ideal for hot locations because it tends to thrive in a drought-resistant fashion. It grows fast, has no problem in poor soil, and it produces a vibrant mix of colors ranging from red to brown to gold.

However, it propagates and lasts only a short while, so lots of Blanket Flower have to be in the strategy to really produce a noticeable bloom for a yard. It pretty much lasts about the duration of summer and then is gone.

Bougainvillea Vine (Bougainvillea)

A close up of beautiful bougainvilleas.

This plant grows fast and covers a large amount of area if it has the right mix of water and soil. It is actually very sensitive to too much water and does better in drier soil with good irrigation. Originally from Brazil, Bougainvillea vine grows upward and then into hanging branches that bloom beautiful purple and deep reddish flowers.

Most people have seen the vine in the front of homes attached to the fence or the colonnade to a doorway and not realized what exactly it was. However, get too close, and the dry wood thorns will remind you of the plant’s defenses. The thorns are sharp, will pierce through clothes and shoes, and tend to be anywhere from an inch to two inches long.

Chrysanthemums (Chrysanthemum)

A bunch of red orange chrysanthemums.

Growing best in shade out of the direct sun, chrysanthemums are the classic bunch flower that people like to have a yard. The plant comes in a variety of different colors ranging from white and yellow to deep purple or orange and red. Unfortunately, chrysanthemums don’t last long.

Aside from being extremely sensitive to insufficient watering, they have a short lifespan and then the plant seems to die off. However, left where it is, the chrysanthemum will almost always grow back and bloom again in the early summer.

Coralbells (Heuchera)

A close up of a cluster of coralbells.

It goes by the name Alumroot as well, Coralbell is quite popular for the coloring of its blooms. Maturing into a deep, royal purple when fully developed, Coralbell lives a perennial and shows up the most in the early summer, finishing off the tail end of the warmer part of spring.

The flowers themselves are not large, tiny pitches of color on delicate stalks, but in mass, they create a noticeable color effect that really comes out in the later afternoon as the lower sun thickens colors in a yard.

Coreopsis (Coreopsis)

A close look at a few coreopsis flowers.

This summer flower, also named Tickseed, at first mention might sound like a health condition. However, Coreopsis grows extremely well in warm areas. Its appeal is the fact that the plant doesn’t need much care in terms of hands-on gardening. Once established, the flower grows on its own and thrives very well as long as the Coreopsis is not overwatered. Again, irrigation is a big player in avoiding problems.

Dafodils (Narcissus)

A garden of sunny yellow daffodils.

Another perennial, the daffodil comes in a handful of colors giving homeowners a bit of variety to play with, depending on where the flowers are placed. They are most desired because of the blooming smell.

The fragrance from a daffodil is strong and easily pervades the surrounding air. No surprise, these plants are also a big attractant for bees and bumblebees, both of which are positive for pollination and healthy growth of all plants in the same yard.

The Dahlia (Dahlia)

A close up of a few gorgeous purple dahlias.

Dahlias really mix things up. They are not a uniform plant, instead of growing in different sizes and different colors, even in the same batch. The flower petals tend to be symmetrical, and how the dahlia is fed will affect its growth rate and size output.

Daylilies (Hemerocallis)

A close inspection of a stunning red and yellow daylily.

Often used with other summer flowers to really mix up a color portfolio in a landscape, the daylily is a versatile plant that can grow in different soil types. Dry or wetter, daylilies find ways to grow where other summer flowers don’t thrive. Hold back the water a bit and keep them out of the harsh, direct sun, and daylilies easily can last an entire summer until the Fall cooler days begin to arrive.

Globe Amaranth (Gomphrena globose)

A bunch of gorgeous globe amaranth.

Shaped like a clover, this plant does well on hot locations as long as it has regular access to moderate water flow. Partial shade gives it the ability to grow off of reflected light, and the blooms are deep with reds and purples. The globe amaranth will spread comfortably with mild care and gardening, easily lasting through the hot parts of summer.

Gloriosa Daisy (Rudbeckia hirta)

A close look at a gloriosa daisy in full bloom.

Also known as the Black-Eyed Swan to flower connoisseurs, the Gloriosa Daisy is a great pick for larger plant interests.

The Gloriosa Daisy is very comfortable in hot climates and has no problem with higher temperatures. When the blooms arrive, the flowers range from a bright yellow to solid orange, but the center of the bloom will be dark to even black, providing a notable contrast.

Lavender (Lavandula)

Very much a drought-resistant pick, lavender does well in desert conditions and dry soil. The plant grows with an amazing ability to provide ground cover fast, and the blooms show up like spikes of blue and purple above the plant. The smell is strong and pungent, easily exerting a strong presence in a yard throughout the summer. The leaves can be used for fragrance in the home, cooking, and more. No surprise, anyone who grows herbs easily has lavender in their yard as well.

Lilies (Lilium)

A beautiful cluster of lilies on a green leaf background.

A favorite in the summer and professional landscapes, lilies are a mainstay and oftentimes the first recommendation for summer flowers when people ask. They have no problem growing even in the harshest of summer weather, and the plant has a built-in ability to recapture and hold water when other plants will dry and shrivel. It might look like the leaves have dried up, but all that has happened is that the lily and the bulb stay alive by the sacrifice.

The Lotus (Nelumbo nucifera)

A beautiful pink lotus flower on a pond.

Originally from India, or at least the country believes so making the Lotus its national flower, the lotus is a bright color addition to a backyard when in bloom.

The flower has often been associated with good times and prosperity, and it is regularly seen as a sign of the best time of the year when things are plentiful.

It does well in hanging baskets or in ground-level soil, and many in the cities put them in planter boxes on balconies.

Pineapple Lily (Eucomis)

A close look at the gorgeous pineapple lily flowers.

While this flower definitely doesn’t resemble a strict pineapple, there are some slight similarities. Much of that has to do with the fact that the pineapple lily comes from the same plant family as the asparagus. The pineapple lily does just find in hotter temperature, and unlike a lot of flowers, this plant does just fine indoors in a pot as well. The plant retains its manageable size, only growing 15 inches in height at its maximum.

The Plumeria (Plumeria rubra)
