If you've ever enjoyed the sight and scent of a beautiful rose, you've likely wondered about the secrets that lie beneath these soft and fragrant petals. To unravel some of these mysteries, New Product Manager Aviram Krell from Plantec - representing global rose breeders in Ecuador - volunteers to tell you all you want (and need) to know about the roses that are bred and grown in South America. For florists, this is a must-read to be completely informed and updated on the most famous and most sold flowers in the world.

South America's Unique Climatic Conditions

Aviram shares insights into the unique climatic and soil conditions in South America that contribute to the distinct characteristics of their roses. According to him, the variety of Ecuadorian soil, ranging from loamy to nearly clay, plays a significant role. However, it's the interplay of light quality and quantity, coupled with the stark temperature differences between day and night, that truly sets South American roses apart. These conditions allow the roses to photosynthesize vigorously during the day and fortify themselves at night, resulting in the biggest, most robust, and beautiful blooms.

The flower's vigor is one aspect, but there are more that make South American roses every florist's dream. For instance its long-lasting beauty. If you're a florist aiming for the longevity of your floral arrangements, South American roses offer a wealth of options. Varieties like Rose Fortune can last up to three weeks in a vase, provided you maintain clean water. Other gems such as Aloha and Jetset also stand out by preserving their color and shape over an extended period.

Altitude plays a pivotal role in the growth and quality of South American roses. Higher altitudes result in larger rose heads, but it may decrease overall plant productivity. The altitude factor brings an exciting dimension to rose cultivation and breeding.

Pest Management Done Right

South America isn't without its fair share of pests and diseases, but Plantec has a strategic two-pronged approach to protect the health and quality of their roses. First, they exercise precise control over humidity, light, and temperature inside their greenhouses. During disease-prone seasons, such as when downy mildew is prevalent, they artificially reduce humidity to thwart spore development, minimizing the need for chemical intervention. The second approach leans on biological controls, using beneficial microscopic organisms that boost the plants' resistance to diseases or eradicate pests without harming the roses.

Plantec's commitment to sustainability doesn't go unnoticed. They've partnered with NUF, an Israeli company that developed ultra-filtration filters used in agriculture. These filters have the incredible capacity to recycle water, removing all pathogens, bacteria, spores, and pests while preserving fertilizers. This technology offers both sustainability and cost efficiency, representing a significant stride in eco-conscious rose cultivation.

Blossoming Innovations

Innovations and breeding techniques are vital to enhance fragrance, color, and durability. Plantec is focused on developing distinct genetic lines like the 'Crown' roses line from German breeder Kordes Rosen for large buds and the 'Hashtag' line from Dutch breeder Interplant for innovative spray roses. These unique traits enable clients to easily distinguish roses that last longer, thus elevating the customer experience.

It is important for Plantec to be differentiated and innovative. Aviram knows that discovering rare and unique rose varieties in South America can be a treasure hunt for florists. He highlights roses like Rose Symbol and Rose Heart of Gold for their distinct colors. Furthermore, the world is now finding the availability of Rose Red Panther, and experiencing this new texture in their works, and that of her brand new sister, Pink Puma.

The diverse cultural influences in South America have given rise to roses of particular cultural or symbolic significance. The blue rose, a long-standing dream for the industry, has now become a reality with the introduction of Rose Shocking Blue. This groundbreaking variety adds a unique color to the world of roses and is set to delight designers and event planners.

Transport and Storage

Plantec goes the extra mile by testing roses globally before deeming them worthy. Some roses, while thriving in Ecuador, might not withstand air freight conditions. Their commitment to quality ensures that any rose variety from Plantec is rigorously tested and guaranteed to provide excellent results.

The transportation and storage of roses are done differently by farms for customized results, but Plantec's goal is to introduce easy to handle, and easy to pack long-lasting roses. Their natural breeding process ensures that no artificial genetic modification is involved, providing a seamless experience for farmers and florists alike.
