The Fragrance Of Tulips: A Sensory Exploration

Although tulips are best known for their vibrant colours and shapes, some varieties do have a pleasant fragrance. In fact, a study conducted in Japan in 2012 identified over 130 chemical components generating the scents of tulips. Tulip scents can be grouped into nine categories: Anise, Citrus, Fruity, Green, Herbal, Herbal-honey, Rosy, Spicy, and Woody. While some tulips have no scent, others, like the 'Apricot Beauty' and 'Generaal de Wet' cultivars, can perfume an entire room.

Most tulips are odourless but some have a pleasant fragrance

Most tulips are odourless but some cultivars have a pleasant fragrance. In fact, a study conducted in Japan in 2012 identified over 130 chemical components generating the scents of tulips. The compounds identified allowed researchers to arrange the flowers according to their odour profiles into nine scent groups: Anise, Citrus, Fruity, Green, Herbal, Herbal-honey, Rosy, Spicy, and Woody.

The diversity of floral scents in tulips is thought to be caused by about 183 scent compounds, ranging from terpenoids and benzenoids to fatty acid derivatives. The major scent compounds include five monoterpenoids (such as eucalyptol and linalool), four sesquiterpenoids (such as caryophyllene and a-farnesene), six benzenoids (such as acetophenone and benzaldehyde), and five fatty acid derivatives (such as decanal and 2-hexenal).

While most tulips have no scent, some varieties have a subtle, fruity fragrance. For example, the 'Apricot Beauty' tulip cultivar has a wonderful, subtle, fruity fragrance and can perfume an entire room. Other fragrant tulips include 'Generaal de Wet', 'Prinses Irene' (often sold as 'Princess Irene'), and 'Couleur Cardinal', a dark-red flower with a violet blush and a light, sweet scent.

Fragrant tulips can be enjoyed indoors and out. They can be planted near garden benches and along paths so their fragrance can be enjoyed during leisure time in the garden. They can also be cut and placed in a vase to bring their sweet smell inside.

A 2012 study identified over 130 chemical components generating the scents of tulips

A 2012 study conducted in Japan examined the floral volatiles emitted by the fresh flowers of various tulip cultivars. The study identified over 130 chemical components that generate the scent of tulips. The researchers were able to categorise the tulips into nine scent groups based on their odour profiles:

• Anise: Spicy and sweet, smelling like Christmas pastry.
• Citrus: Fresh and juicy or more intense and oily, like orange peels.
• Fruity: Ranging from fresh and juicy to sweet fruity and even faint bitter almond-like.
• Green: Delicate, grassy-green notes.
• Herbal: Defined by herbaceous notes.
• Herbal-honey: Composed of intertwined herbal and sweet honey odours.
• Rosy: Light, rosy scents.
• Spicy: Spicy, humid and at times medicinal.
• Woody: Hardly perceivable woody notes.

The study highlights the diversity of floral scents found in tulips, which is often overshadowed by their vibrant colours and shapes. While the majority of tulips are odourless, some cultivars exhibit a pleasant and intense fragrance. The identification of the chemical components responsible for the scent of tulips provides valuable insights into their fragrance analysis and can promote the development of the tulip fragrance industry.

Tulip scents can be grouped into 9 categories, including anise, citrus, fruity, and herbal

While most tulips are odourless, some varieties do have a pleasant and sometimes intense fragrance. In a 2012 study, researchers in Japan identified over 130 chemical components generating the scents of tulips. They then grouped the flowers into nine scent categories based on their odour profiles:

Anise

The anise group includes seven tulip cultivars, such as 'Candy Prince', and is characterised by a spicy and sweet fragrance reminiscent of Christmas pastry.

Citrus

With 21 cultivars, including 'Advance', the citrus group is one of the largest. These tulips have a fresh and juicy aroma, or a more intense and oily scent like orange peels.

Fruity

The 14 members of the fruity group, including 'Sane', offer a range of fragrances from fresh and juicy to sweet and fruity, with some having a faint bitter almond-like note.

Green

Sixteen cultivars, for example 'Cum Laude', make up the green group. Their scent is characterised by delicate, grassy-green notes.

Herbal

Another large group with 16 members, including 'Davenport', the herbal group is defined by herbaceous notes.

Herbal-honey

Only one tulip cultivar, 'Nagoriyuki', falls into the herbal-honey group, which combines herbal and sweet honey odours.

Rosy

The two members of the rosy group, including 'Monte Rosa', emit a light rosy fragrance.

Spicy

The spicy group, including seven cultivars such as 'Ben van Zanten', has a spicy, humid, and sometimes medicinal fragrance.

Woody

The final group, with just two members, including 'Queen of the Night', has a woody scent that is difficult to perceive.

Fragrant tulips include 'Apricot Beauty', 'Generaal de Wet', and 'Prinses Irene'

While most tulips are odourless, some varieties do have a pleasant fragrance. Fragrant tulips include Apricot Beauty, Generaal de Wet, and Prinses Irene.

Apricot Beauty is a sweet-scented, early-blooming tulip with soft apricot flowers that shimmer in the sunlight. Blooming in early-to-mid-spring, it has a strong stem that can withstand wind and rain. This award-winning tulip is considered one of the prettiest apricot cultivars and is a favourite among gardeners.

Generaal de Wet is another early-blooming, fragrant tulip with cup-shaped, juicy orange petals and darker orange shading. Introduced in 1904, this heirloom variety is also known for its sturdy stem and is regarded as one of the most attractive orange cultivars.

Prinses Irene is a unique, scented tulip with a brown flame in its orange flower. This short, sturdy variety is well-suited for pots and combines beautifully with its yellow and pink relatives, Ravanna and Pretty Princess.

These three tulip varieties offer a delightful fragrance along with their vibrant colours, making them excellent choices for gardeners and flower enthusiasts.

Fragrant tulips can be planted near benches and paths so their scent can be enjoyed outdoors

While most tulips are odourless, some varieties do have a pleasant and sometimes intense fragrance. A fragrant tulip can be a wonderful surprise, as one gardener discovered when she noticed a subtle, fruity fragrance in her garden one spring morning. The source turned out to be a peachy-pink tulip called 'Apricot Beauty'.

There are thousands of varieties of tulips, but only a small number are fragrant. These scented varieties include early-blooming types such as 'Generaal de Wet', a softly blushed orange tulip; 'Prinses Irene' (often sold as 'Princess Irene'), another sweet-smelling orange flower; and 'Couleur Cardinal', a beautiful, dark-red flower with a violet blush and a light, sweet scent. Some of the early, double-flowered tulips are also fragrant, including the yellow 'Mr. van der Hoef'; 'Electra', a pinkish-red beauty; and 'Schoonoord', a pure white.

Among the midseason fragrant tulips are 'Silverstream', a pale, creamy colour with a fine, sweet scent, and 'Holland's Glory', which sports huge orange-red blossoms on strong, 2-foot-tall stems. 'Holland's Glory' makes a perfect pair with another fragrant Darwin hybrid, the yellow-red 'Rainbow Warrior'.

When planting tulips, it is important to ensure they are in well-drained, cool soil. Planting them fairly deeply, with at least 8 inches from the soil level to the top of the bulb, will help keep the bulbs cool. Tulip bulbs also benefit from being planted in the fall and receiving a fall feeding.
