Varieties of Tall Yellow Perennial Flowers

If you’re looking to brighten up your outdoor garden with a dazzling splash of gold, you can’t go wrong when it comes to tall yellow perennial flowers. 

Their towering height and bright coloring are an attractive visual addition to any outside display. And they’re not just appealing to gardeners and other flower enthusiasts. Bees and butterflies find them equally irresistible. 

So, if you want to add another distinctive layer of color to your garden’s rainbow, one that is guaranteed to inspire a whole host of equally beautiful wildlife to take up residency in your backyard, take a look at the wide variety of tall yellow perennial flowers!

Types of Tall Yellow Perennial Flowers

Of all the colors in the prism, the most luminous is yellow. This means that even on the greyest of days, your tall yellow perennial flowers will definitely and dazzlingly stand out with their glorious hues. 

As a general note, there are two main types of yellow in the flower world: cool and warm. When flowers are pure yellow or slightly tinted with green undertones, these are considered excellent. Flowers of a richer yellow or those underscored with traces of red are designated as warm. 

Aside from their impressive height and their eye-catching color, these flowers are also perennial, which means they return on a yearly basis. You need not worry about having to replant new flowers every year as you would with annuals. Many species of tall yellow perennial flowers are also quite hardy and require very little care once correctly established. Some tenacious varieties are even robust enough to withstand the harsher winter months!

Most tall yellow perennial flowers thrive best in full direct sunlight – no surprise when considering how well these blooms capture and reflect the sun’s own magnificence! On hot days, however, a bit of shade might be required. 

By now, you’re probably eager to learn more about some specific varieties of tall yellow perennial flowers. To help you choose which ones are most suitable for your garden, I’ve included a list below of some of the most popular species as a guide. Let’s take a look! 

1. Sword Lily (Gladiolus charisma

Sword Lily
  • Best grown and maintained with total light exposure.
  • Requires a soil rich in humus and well-drained. 
  • Toxic to animals, including cats, dogs, and even horses. 

The Sword Lily is a tall yellow perennial flower that truly is deserving of the second word in its scientific name, for when it comes to appealing beauty, this plant is all charisma! With blooms that open from the bottom of its slender stalks, an eye-catching display of golden ruffles delights the senses of humans, bees, and butterflies alike. And because the stalks can reach a height of up to four or five feet, the beauty of the Sword Lily’s blooms will be pretty hard to miss! 

The ideal regions in which to grow the Sword Lily are USDA Zones 8 through 11, where they can receive plenty of whole, direct sunlight. If the weather conditions are suitable, you can expect to see your Sword Lily bloom throughout the entirety of the summer season. 

Make sure you use well-drained, humus-rich soil when planting your Sword Lillies, and always make sure the ground surrounding it is moist during the growing season.

Be advised that if you have pets or your garden is situated on a farm, the Sword Lily is beautiful, though it may be, unfortunately, toxic to a wide range of animals, including cats, dogs, and horses. 

2. Yellow Lady Banks Climbing Rose (Rosa Banksiae Lutea

Yellow Lady Banks Climbing Rose
  • Thrives best in full sunlight. 
  • They are considered relatively non-toxic to humans and animals. 
  • Requires acidic to neutral soil. 

If height is what you’re after, you can’t go wrong when it comes to a climbing rose. And if beautiful coloring is what you’re after when it comes to a climbing gown, you can’t do better than the Yellow Lady Banks Climbing Rose. 

The coloring of the Yellow Lady Banks Climbing Rose veers more to the cooler side of the yellow spectrum, with soft undertones of blue and green to counterbalance the subdued goldenness of its blooms. 

If you’ve got the right kind of support and enough space to grow them, you won’t be disappointed with the Yellow Lady Banks Climbing Rose, as they can reach heights of up to fifteen to twenty feet. These delightful flowers grow exceptionally rapidly and require very little in the way of ongoing maintenance. Aside from periodically pruning away any dead wood, the only other time you’ll need your gardening shears is if you want to reduce the plant’s size. 

Be sure to give your Yellow Lady Banks Climbing Rose plenty of whole, direct sunlight and take care to water it whenever you notice the top three inches of the surrounding soil is dry. This species of rose grows best in USDA Zones 9 through 11. 

Oh, and it’s not just your eyes that will be attracted to the blooms of this delightful plant. The Yellow Lady Banks Climbing Rose also gives off a unique and charming aroma. And unlike other members of the rose family, she doesn’t have any thorns! Easy on the eyes and easy on the hands! 

3. Sunflower (Helianthus

  • As its name implies, it requires full sunlight for growth and maintenance. 
  • Species vary, with some perennial varieties requiring dry soil and others moist. 
  • Considered non-toxic to both animals and humans. 

Probably the most recognized name when it comes to the varieties of tall yellow perennial flowers is the Sunflower. The unmistakable blooms of this towering plant have been etched into the minds of children and adults alike from time immemorial. 

The sunflower’s ubiquitousness as a famous species of plant is the result of a variety of factors. 

Firstly, the attractiveness of its sizeable and fittingly sun-shaped flowers is appealing not only to humans but to bees and butterflies as well, inspiring entire ecosystems to develop in its midst. 

Secondly, the majestic height of the giant varieties offers them a commanding presence in any garden or field, with some species reaching heights of well over eight feet! 

Lastly, its unique seeds have long been considered a tasty and healthy snack. It’s quite a rare treat when a plant can provide both visual beauty and delicious taste! 

When planting your sunflowers, especially the giant varieties, be sure you’ve selected a well-sheltered area of your garden with plenty of support to sustain these top-heavy climbers. 

Also, it’s essential to include copious amounts of organic material in your soil, such as manure or garden compost. The University of Florida has more information on which soils to use. 

Take care to water them regularly and, as the name indicates, give them plenty of direct sunlight! These flowers thrive best in USDA Zones 4 to 8. 

4. Rocket (Ligularia stenocephala) 

  • Requires heavy watering.
  • It can thrive best in partial shade and limited, indirect sunlight. 
  • This plant is not known to be toxic to either humans or animals. 

This upward shooting tells that yellow perennials are an ideal choice for those gardeners dwelling in wetter climates as they require quite a deal of moisture to thrive optimally. Usually found naturally in USDA Zones 4 through 8, the Rocket, as it is commonly known, can reach heights of up to five feet with a leaf spread of around four feet. 

The lemon-yellow blooms of The Rocket make it an ideal addition to any outdoor flower scheme. If your garden happens to be situated near a pond or other similar boggy area, you’ll have a relatively easy time when it comes to growing and maintaining this plant. Otherwise, be sure that the soil you’re using to cultivate your Rocket always retains its moisture. 

The blooming season for The Rocket is generally shorter than that of other perennials, lasting only from June to July. However, one added visual advantage to this plant is that even when it’s not in bloom, the lush green foliage that forms its distinctive clumped base retains its attractiveness all year round. 

Some shared garden pests to look out for when caring for your Rocket include slugs and snails, which find the leaves a tantalising delicacy. Also, be advised that this plant is very susceptible to withering in hotter weather under direct sunlight, so again, always make sure that the water surrounding it is continuously watered. 

This tall yellow perennial is not known to be toxic either to animals or to humans. 

5. Cannova Yellow (Canna generalis

Cannova Yellow
  • Performs best in full, direct sunlight. 
  • Requires organically rich and heavily watered soil. 
  • Considered non-toxic to both humans and animals. 

Perhaps you’d like to add a little tropical flair to the borders of your garden. If so, you might consider purchasing some Cannova Yellows. These golden flowered perennials are a fitting addition to liven up any monotonous garden color scheme. 

The Cannova Yellow is exceptionally hardy in USDA Zones 8 through 11, where it can reach heights of up to four feet once in full bloom. Its exotic flowers crave the heat, so it’s a good idea to plant them in a good position where they can receive full, direct sunlight. Try to dig in as much organic material as possible into your soil, like manure or garden compost, and keep it as moist as you can for optimum growth. 

Be advised, however, if you’re attempting to grow your Cannova Yellow in locations outside of USDA Zones 8 through 11, these plants are susceptible to conditions of frost. Because of this, you may want to dig up some bulbs before the winter and store these in a safe place until you can replant them in the following spring. 

By and large, the Cannova Yellow doesn’t suffer too much from garden pests, with the exception of caterpillars, snails, and slugs that sometimes chew on the foliage. Why, it’s even robust enough to withstand the intrusion of deer! 

The Cannova Yellow is considered non-toxic to both animals and humans. 

6. Goldsturm (Rudbeckia fulgida) 

  • Requires organically rich soil and plenty of moisture.
  • Grows best under conditions of direct, full sunlight. 
  • No toxic effects on either humans or animals have been reported. 

If, like most people, you’re never quite ready for the summer to end, then this late blooming tall yellow perennial may be just what you require. From August to September, the Goldsturm unleashes a dazzling array of golden yellow daisy-shaped flowers with distinct black eyes. Just think about it! At a time of the season when most of your garden is starting to lie dormant, the Goldsturm is just coming to life! Who says summer has to end? 

Long considered one of the USA’s most popular perennials, the Goldsturm can be found across a wide swath of the country, from USDA Zones 3 through 9. Under proper growing conditions, this plant can reach a height of up to three feet with a leaf spread of two feet, making it an ideal addition to almost every type of garden. 

Make sure to place your Goldsturm where it can receive plenty of whole, direct sunlight and try to include as much organic material as possible into your soil before planting. As the University of Wisconsin says, keep your surrounding area moist but well-drained, and you’re guaranteed to see some lovely effects! 

Because the Goldsturm is a pollinating plant, you can also expect to have the beauty of your garden amplified by the presence of nectar-guzzling bees and butterflies. However, it’s not so inviting to other creatures as it’s been proven resistant to both rabbits and deer! 

No toxic effects from this plant have been noted in either humans or animals.
