In Great Britain, you simply can’t go more than a few yards ithout seeing a basket or window-box of Petunias, whether it’s outsider a bungalow or a pub!
Did you know though, they weren’t always so welcomed. Back in the 1500s, most British people believed they were a symbol of the demonic powers of satanism, ooooh gosh! Thousands of years later, they’ve become the nation’s most loved summer-bloomer.
But, let’s look at how a lanky plant become the candy box of colours it is today…
Part of the popular Solanaceae family (which includes Tomatoes and Aubergines), the very first species discovered was Petunia axillaris, hunted down by Spanish explorers in South America in the 16th century. Petunia axillaris is low-growing and covered in fragrant white blossom.
After a large gap, another Petunia species was founded, in 1831. Petunia violacea was found by Scottish explorer James Tweddle. He brought the plant back from the Americas to the Glasgow Botanic Gardens. It wasn’t until later in the 1800s that breeders began to experiment, wanting to create types with larger petals and in a many more colours.
Alas, you can now grow a Petunia in almost any colour of the rainbow! There are double blooms, star-shaped blooms, striped blooms, and that’s just the start!
A petunia’s only demand is a sunny spot. They’ll grow in most soil types. The flowering season can stretch from late June to September, and beyond.
One key development in the last few years has been the wave of hybrids between Calibrachoa and Petunia. Calibrachoa initially entered the market and a filler for baskets and pots, but could also hold their own as a specimen. The colour spectrum and combinations available were like a horticultural sweet shop too.
The triumphant ‘BeautiCal’ hybrid of Petunia and Calibrachoa (x Petchoa) sports a bushy petunia shape, yet with large Calibrachoa-looking flowers. There’s no compromise on weather performance either!
Fragrance is usually hit and miss with Petunia, despite the early finding Petunia violacea having a strong sugar scent. However, BeautiCal have both colour, fragrance and flowering performance in abandon!!
I truly think this new hybrid will become the plant of choice for baskets, window boxes, planters – whether in public or private locations!

How would you compare the Beauticals with Proven Winners’ Supertunias? (If they are available in UK?) I have 3 that I bring in and out of my greenhouse. They flower energetically but no smell. But they are on ground level so I would be reluctant to get down to sniff them very often, LOL.
