Our group

We are an informal group of four family nurseries building a joint brand.

The oldest company – Gospodarstwo Ogrodnicze Tadeusz Kusibab (GOTK), existing on the market since 1981, deals with plant micropropagation (i.e. plant propagation using the in vitro culture technique). Offers only laboratory material.

Plantin – offers, most of all, plants in multiplats bought only in bulk for further nursery production and a small range of plants in p9 pots.

Gospodarstwo Ogrodnicze Aleksandra Kusibab-Wyka (established in 2007) and Gospodarstwo Ogrodnicze Waganowice (established in 2010) are sister companies which offer slightly older plants (sold in P9 to C3 pots).

All the plants offered by our nurseries originate from the in vitro laboratory in GOTK. We propagate both fruit plants such as the highbush blueberry, honeysuckle (haskap), the giant-fruit blackberry, raspberry, serviceberry (saskatoon) and chokeberry, and ornamental plants, such as: rhododendrons, azaleas, kalmias, cherry trees and birch trees.

Our assets

The quality of plants

Producing and selling the best quality plants is the highest priority of the in vitroKusibab Group and that is why we constantly invest in research. Every year PLANTIN orders special tests to examine and confirm the general health of plants on offer by our companies. Thanks to them we are certain that the plants propagated by us are free from viruses and examined paying special attention to the varietal identity and purity.

The plant samples for tests are collected and marked by trained personnel


the Blueberry tests conducted at the Horticulture Department of the University of Agriculture in Krakow, Poland


the Blueberry tests conducted at the Institute of Horticulture in Skierniewice, Poland

regularly since 2007

the Blueberry tests conducted at the Agdia Incorporated, USA


the Blueberry tests conducted at the Centre for Certified Nursery Stock in Prusy, Poland

regularly since 2013

the Blueberry tests conducted at the Main Inspectorate of Plant Health and Seed Inspection in Krakow, Poland

regularly since 2019

the Blueberry tests conducted at the Institute of Horticulture in Skierniewice, Poland


We examine whether the Blueberry plant samples contain the following viruses:

  • Blueberry leaf mottle virus
  • Blueberry scorch virus
  • Blueberry shock virus
  • Blueberry shoestring virus
  • Peach rosette mosaic virus
  • Tobacco ringspot virus
  • Tomato ringspot virus
  • Blueberry red ringspot virus (since 2019)
  • Blueberry mosaic associated virus (since 2019)
  • Blueberry witches broom phytoplasma (since 2020)
  • Blueberry stunt phytoplasma (since 2020)

Since 2014 we have also been examining mother plants of the raspberry and blackberry varieties originated from the PLANTIN insect proof tents. The Institute of Horticulture in Skierniewice, as ordered by our company, conducts the Elisa and RT-PCR tests to confirm the absence of viruses in our plants.

Expertise and experience gained over the years in the horticulture business is reflected in the quality of plants produced by us.

PLANTIN (formerly Gospodarstwo Ogrodnicze Tadeusz Kusibab) is the eldest in the in-vitro Kusibab Group and has been on the market since 1981!

The beginnings of the in vitro propagation go back to 1978 when Tadeusz Kusibab (PLANTIN co-owner) commenced the first attempts at propagating orchids. In 1981, the laboratory started propagating the rhododendrons which became leading products for many consecutive years.

A thorough expertise and gaining new experience in the field of the in vitro propagation, plant nurturing, fertilization, irrigation, etc. and implementation of new technologies have allowed us to thrive on the market for almost 40 years now!

Gospodarstwo Ogrodnicze Aleksandra Kusibab-Wyka and Marcin Wyka, which most of all deals with the Highbush Blueberry in p9 to C3 pots, originated in 2007. Gospodarstwo Ogrodnicze Waganowice Paulina Kusibab-Popowicz and Mirosław Popowicz, which most of all deals with the sale of Blueberry in p9 pots, originated in 2010. From the very beginning all the three companies have been cooperating with one another and recently they have joined their marketing efforts and created a group of the in-vitro Kusibab producers.

We supplement one another (offering plants of different height) and are building a joint brand.

A many-year long expertise, presently handed over to a younger generation, is a guarantee of high quality of plants on our offer.

A wide range of products on offer

We constantly broaden the range of plant varieties on our offer, looking for new varieties which can meet the expectations of the developing market.

Presently the PLANTIN laboratory propagates 300–400 taxa.

The berry plants, especially the Highbush Blueberry and the Honeysuckle (Haskap), but also raspberries, serviceberries and chokeberries belong to the leading varieties. We also propagate ornamental varieties such as rhododendrons, azaleas, kalmias and cherry trees.

Based on a many-year long experience in numerous plant genera we are open to propagate new varieties entrusted to us by our clients.

Our laboratory

The in vitro propagation - technology of contemporary times and the future.

The production of our plants begins in special, controlled conditions – in the in vitro cultures laboratory (i.e. on the glass). The in vitro process consists in accelerating the growth of plants in a controlled way. By implementing thoroughly selected growth regulators we appropriately stimulate plants to develop (e.g. their roots or side buds). Young plants growing in sterile conditions have optimal growth and development conditions. Ample lighting conditions, properly selected composition of the media, specific temperature and humidity make that it is possible to considerably accelerate the propagation process.

At the end of 2018, a new laboratory was opened at the Krakow head office of GOTK. Its surface area equals 625 m2 and it has 15 production stands equipped with new technology facilitating the production of plants. In our collection, we possess approximately 400 taxa of plants ready at any time to begin production anew. Every year we introduce about 30-40 new taxa and prepare them to a potential commercial use.

The next stage of our production consists in acclimatizing plants under covers and gradually hardening them off. During that stage, plants depending on their development, are replanted to multipots and then to greater containers.
