Why plants should be bought in odd numbers

Key Takeaways

• Odd numbers create visual variety and aesthetic impact.
• Clusters of plants are what we see in nature, making odd-numbered groupings look more natural.

• Even numbers can bore the eye and appear unnatural.
• Uniformity doesn’t work well in gardening—it’s an art form!

• Garden centers often offer discounts for plants bought in 3s.
• So, buying in odd numbers can actually help you save money—especially when settling into a new home.

“My golden rule of plant buying is that plants should always be bought in 3s, 5s, 7s or even 9s. A mistake many gardeners make is planting up in singles, pairs or even numbers. 

“Plants should clump, sprawl and intertwine, not sit in rigid lines or block shapes. Planting in odd numbers creates visual variety and offers maximum aesthetic impact.”

Brian explains why this is: 

Single plants don’t make enough impact 

“Unless you are buying specimens or ‘look at me’ plants like large trees, full shrubs or topiary, single plants don’t offer enough impact. Specimens are types of plant that draw attention, they’re conversation pieces that stand out among other plants in the garden and offer instant impact.” 

It looks most natural 

“Clusters of plants are what we see in nature. Buying in odd numbers is the best way to replicate this effect and make your outside space look natural.”

 

Even numbers bore the eye 

“You also want to avoid even numbers. Gardening is a form of art and, as graphic designers, interior designers and all manner of creatives will tell you, uniformity bores the eye and looks unnatural.” 

It’s cheaper 

“Another added bonus is that garden centres often offer discounts for plants bought in 3s. Therefore, buying in odd numbers can actually help you to save money - especially important when you’ve just moved into a new home.”
