This year it feels like winter has lasted forever! But we have some good news for you. It’s almost that time of year again for barbeques, bike rides, garden parties, and just spending more time outdoors in general. It’s also almost time to begin planting flowers in our gardens for the impending summer season, but with so many vibrant choices out there, how do you decide what to grow? 

We’ve taken the liberty of researching some of the prettiest summer blooms for you along with some tips to grow them loud and proud. Our first tip? The best day of the year to plant your garden in time for summer is Mother’s Day because the danger of frost has passed by then and, for some seeds, the soil is just the right temperature.

If you want your garden to stand out this year, continue reading and try adding some of these flowers that are sure to add an exotic look and feel to your yard.

Hydrangeas

Hydrangeas

Hydrangeas are a classic staple of flower gardens, and they're particularly popular when Easter and Mother's Day roll around. No matter what your favorite color is, there's almost certainly a hydrangea variety that you will absolutely love. Although older varieties can be finicky to care for, newer varieties have been developed that are much easier to keep alive, even if you don't have a green thumb. 

Planting Tip: Hydrangeas are more shrub than flower and can grow to be 20 feet tall or wide. So, when planting them, plan ahead and make sure that you have plenty of room around them for them to grow and thrive. 

Zinnias

Zinnias

These almost exotic flowers look similar to dahlias and attract butterflies. Planting them on Mother’s Day will guarantee they make an appearance by early July.

Planting Tip: Zinnias don’t do well after transplantation so make sure to place them where you want them based on height and color. Taller varieties should be spaced at least a foot apart.

Canna Lilies

Canna Lilies

These tropical-looking blooms can be red, yellow, or orange and have lush foliage to add an exotic look to your garden. You can place them in mixed borders or group plantings to get the most dramatic effect.

Planting Tip: Planting them after the threat of frost has passed will give them time to establish themselves and yield the most intense blooms all season.

Stargazer Oriental Lily

Stargazer Oriental Lily

There are tons of lily varieties out there, but one of the most colorful has to be the "Stargazer" oriental lily. These bright pink blooms are beautiful and highly fragrant, and they bloom in the middle of summer—meaning that spring is the perfect time to plant them. 

Planting Tip: This is one flower you definitely want to avoid if you have cats. All varieties of lily, including the Stargazer, are highly toxic to them. Thankfully, there are plenty of equally colorful, safe alternatives for cat fans out there! 

Daylilies

Daylilies

These unique, multi-flowered stems can grow in all types of soil, require very little attention, and will grow for years and years. What gives them their unique quality, you ask? They bloom in the mornings and die again by nighttime.

Planting Tip: These beauties are best grown in full sunlight. Also, they are best for landscape planting in groups of three or five, or they can be mass planted along a fence line for a dramatic effect.

Lavender

Lavender

The buds of this beautiful flower are actually fragrant herbs that are a natural antiseptic. They can be useful for things like cuts, burns, insect bites, and other skin irritations. Not to mention that their fragrance can help to relax or destress and attracts butterflies and birds to your garden.

Planting Tip: Each plant can flower 300 – 400 stems during full bloom, but they need a dry and arid climate. Some hybrids like Sweet Lavender or Provence Lavender can tolerate humidity better.

Irises

Irises

These loud and proud flowers come in a wide spectrum of colors and are a beautiful addition to any yard; however, they do better in a bed of their own. Spreading them across a landscape gives the most dramatic effect.

Planting Tip: These flowers need at least six hours of sunlight per day with good soil drainage. Plant them in groups of three, at least one to two feet apart. In addition, dividing the bulbs every few years will reinvigorate growth.

Hellebore

Hellebore

While it's not the flashiest flower you'll encounter, the hellebore is a great, beautiful addition to your spring garden. These dark purple blooms can last for years to come as long as you give them the TLC they need to make it through that first growing season. Once that's over with, they rarely need to be watered. 

Planting Tip: Planting hellebore in raised flower beds can help you to appreciate their beauty more. Since they bloom downward, it can be difficult to see the flowers if they are planted directly in the ground. 

Blanket Flowers

Blanket Flowers

These flowers can come in multi-colored fashion and look like a miniature sunset or they can come in solid shades of yellow, wine, red, orange, and peach give a long-lasting show of bright foliage all season long. They thrive in sunny, dry, and rocky conditions and need little to no care.

Planting Tip: This particular flower does not do well when fertilized. The average amount of rainfall each season is enough water for them to grow but may need watering in conditions of drought.

Sweet Pea

Sweet Pea

Sweet Peas are the perfect addition if you want your garden to have a quick and colorful pop in the spring. You can find them in basically any color you can imagine, so coordinating them with your other flowers shouldn't be a problem at all. 

Planting Tip: The heat of summer will pretty quickly hurt your sweet peas, so be sure to plant them as early as possible in the spring season. However, if you live in the northern United States, your Sweet Peas may stick around a bit longer than usual. 

Gladiolus

Gladiolus

Gladiolus is technically a summer flower, but you need to go ahead and plant their bulbs in spring if you want them to thrive. These beautiful flowers come in all shades of orange, red, and yellow, and, because they're so tall and thin, they can add a burst of color without taking up a ton of room in your garden. 

Planting Tip: When planting gladiolus, place them close enough that they can lean on one another as they grow. If this isn't possible, you'll need cages or other accessories to help keep them upright as they grow. 

Sedum

Sedum

You've got to be patient with sedum flowers. They need to be planted in early spring, but you won't actually see them bloom until late summer. However, they are more than worth the wait, as they bloom brightly and remain beautiful even after they have died and dried up. 

Planting Tip: Sedum flowers don't like too much of a good thing, so be sure not to overwater them, as the plants are particularly susceptible to root rot. Additionally, they should be planted in sandy, nutrient-poor soil, as this is where they thrive best.

Monkshood

Monkshood

Although you won't see the results of your hard work until late fall, monkshood flowers should be planted in the spring to look their best. While they won't look like much for a while, when these purple-blue flowers bloom, they really steal the show in your garden. 

Planting Tip: While they look beautiful, Monkshood is actually poisonous to humans and pets. You can absolutely grow them safely, but it's best to use gloves when handling them, and they should never be cut and used as part of a flower arrangement.
