‘The secret behind successful breeding
is seeing things differently

Bundled expertise between Hark and Sion

Breeding & propagation

Every day, with a lot of care and passion, our team of enthusiastic breeders is working very hard to develop the most special Phalaenopsis varieties. This starts in our breeding room, which houses a selection of the strongest and most distinctive mother plants.

While Hark Orchideeën is known for its high quality lab propagation, Sion is known for its distinguishing breeding activities. Together we offer years of experience and plant knowledge. With a good dose of creativity, we also produce the most beautiful hybrids with our plants. Each new variety is subjected to a large number of selection criteria. Amongst other things, we look at durability, growth speed and quality, as well as the ability to stand out in the market. By using the latest techniques and strict selection criteria, only the most distinctive and beautiful varieties remain. Together with our clients, each new variety is extensively tested in practice. Approximately 8 years after the first hybrids, this results in the most special and distinctive Phalaenopsis varieties.

In this way we continue to surprise the market as well as the consumer

Together we have more than

100 years of experience 


The company HARK has been active for more than 115 years. People have been working with plants at this same site in Lippstadt, Germany since 1904. In 1949, Fritz Hark laid the foundation stone for today’s company. His good instinct for plants, innovative strength and perseverance were the traits that characterized him. When he bought his first orchid, this was the start of his passion for these fascinating plants, a passion that is still characteristic for our company. In 1967, HARK had a breakthrough in cultivation, with the first pink Phalaenopsis!

The company Sion has been active for more than 35 years. In 1988, Sion entered the world of Phalaenopsis orchids as a grower. In those days, it was not yet possible to order orchids by their variety names. We thought that this was a major shortcoming, if you want to distinguish yourself in the market and create demand for your varieties. That is why Sion started to breed its own varieties in 1993. And with success: in 2008 Sion made the switch to professional breeding and propagation of Phalaenopsis. Our colleague growers became our clients. Sion grows young plants in the Netherlands, which find their way to growers all over the world. From Sion Brazil, we supply to growers in South America.

In 2021, HARK and Sion joined forces. The capabilities of both companies complement each other perfectly. And we have not been idle since then. In 2022 we entered into an exclusive partnership with Bevo Farms in Canada. In addition to Phalaenopsis cuttings in lab cups, this enables Sion to supply propagation material in plug or half-grown with – or without – stem. With a local delivery time of 2 to 4 days, we maintain a tight delivery plan, with weekly deliveries throughout the year or large deliveries during peak periods such as holidays.
Together with our customer we always take ‘The next step in orchids’!
