09.2019: I am very content with this year's harvest. Meanwhile even extra large rhizomes grow in soil within four years due to further improved cultivation methods in the lab and nursery. All this without the use of pesticides, grown under conditions close to nature and outdoors!

06.2019: The hybrids Henric and Schoko are presented to the public for the first time and are ready to be ordered.

Our web-presence is now fully up-to-date after a complete overhaul, including optimized display on mobile devices. To this end we've deliberately kept the layout simple.

05.2019: New garden examples from Belarus illustrate how beautiful and vigorous plantings with hardy lady's slippers can be.

After an extremely dry and sunny year 2018 this spring shows again that Cypripedium hybrids are markedly more robust than species. Even experts have to accept losses or weaker growth of species whereas the hybrids don't show any problems. Some of them are even stronger due to the high amount of light last year!

Cypripedium Henric, for example, is marvellous this year in our nursery.

01.2019: Frosch® Exclusive Perennials is now celebrating 25 years. Our quality, staying-power and love for our products has helped us maintain our position in a challenging market. We have chosen cooperation over competition, helping us to thrive where others have given up. It requires special skill to sustain a business based on Cypripedium culture over this many years!

25 years of Frosch® Exclusive perennials

09.2018: We are very happy about our excellent success in germinating Cypripedium hybrids in the lab this year. Trials and failures in past years haven taken us a great step forward. Also the seedlings from last year's sowing are really good for the first time and meet our highest quality standards.

06.2018: With the update of our website we add advice for nurseries and improve the design for mobile devices even further.

05.2018: For the first time we register a new hybrid at the Royal Horticultural Society in England: Cypripedium Christian. A very promising cross!

03.2018: Stefanie Stuke, a German landscape gardener, made a tattoo of her Cypripedium Dietrich onto the leg of a workmate. Incredible!

02.2018: We make considerable progress with our lab procedure. The in vitro seedlings look better than ever, despite the fact that we made a basic mistake at the start of the sowing season last summer. Next time we know better!

09.2017: The orchid harvest this autumn was very pleasing, the quality excellent. Constant improvements of our culture methods and the newly built protection against weather extremes due to climate change show effect.

Size 0 represents "jumbo size", size 1 flowering size, and size NF will flower in 1-2 years. Please note the extra long roots due to outdoor cultivation!

Rhizomes of various sizes

05.2017: Blooming time in my nursery! It wasn't easy to protect the plants from severe damage by late frosts this year. Our March was unusually warm and so two late frost and snow periods end of April hit the garden orchids shortly before flowering, when they are no longer frost-resistant. That was close, but in the end our frost protection measures turned out to be successful.

A sea of blossoms

03.2017: Publication in the Austrian gardening magazine "Sabine Gartenparadies" (view pdf file).

10.2016: Publication in the Russian online magazine "Ogorod.ru" with many photos (view the article).

With the professional production of cypripediums, there can be a narrow line between joy and sorrow. We have experienced this again during this year's harvest. Some beds gave perfect rhizomes, other beds by far not as good roots due to the extraordinary cold and wet spring this year. We will improve the technical equipment of the critical beds to be more independent from extreme weather conditions in the future.

This is perfect and at real "Frosch®" quality level:

perfect rhizomes

The rhizomes below don't make us really happy. Still they are stable and will grow in any garden, but they are not perfect:

A dream result, my first real clone 'Frosch's Mountain King' in top quality! Please note the length of the roots and the root to shoot ratio. This is the result of a natural way of growing them outside.

This is also the reason why I only sell them as dormant, bare-rooted rhizomes in autumn to nurseries and dealers worldwide.

12.2013: We open our own laboratory for the sterile sowing and raising of seedlings. Until now this task had been given to an external service provider. It takes 15 months before the plantlets are big enough to be transplanted into the unsterile conditions of the nursery. And from there another 3-6 years until the first flower! Not really a job for impatient people...

04.2013: We still have frosty winter weather at the beginning of April. Many nurseries with heated greenhouses complain about high heating costs and flowering outdoor plants which do not sell. Now the strategy of Frosch® Exclusive Perennials pays off. We only grow outside in beds with organic plant protection. In this way our plants remain dormant and wait for spring patiently, without energy consumption and energy costs!
