Virus-Free Canna

Our Protocol

20 years ago, we have developed new techniques in order to grow back our Canna stock as a Virus-Free Canna. Since then we are growing our Canna stock with the highest standards possible.


Although they are not 100% virus-free, Our Cannas are probably the cleanest Cannas rhizomes in the world.

We have never claimed that our field-grown Cannas are not virus-indexed but a Visually Virus-Free, and they are the cleanest regular stocks in the market due to careful following of the growing protocol.


The process begins with clean Tissue Culture plantlets weaned and grown in a Nuclear House.

From these plants, our Mother Stock is produced in a protected greenhouse.

The third step is to produce commercial crops in isolated fields.

The meaning of this process is - that the first steps toward mass production are controlled with clean plants under sterilized conditions.

Saad-Assaf is diligent to keep this stock as clean as possible until it gets to our customers.


But from the moment of harvesting the Mother Stock greenhouse, there are multiple ways of contamination, such as Cutting rhizomes, Storing masses until planting, and even planting and growing in an open field for 9 months. As much as this field is isolated in the middle of the Negev desert- we cannot guarantee 0% contamination.


We know that difficulties are challenging, we know that not all producing steps are in a sterile environment, and we know where are critical control points in our production process.

So we put our effort into these points and we focus on them in order bring the market our advantages.

We do not know of any other company, which has invested in developing such a sustainable protocol for the delivery of good-quality Canna rhizomes for more than 20 years. We know that although they are not 100% virus-free, Our Cannas are probably the cleanest Cannas rhizomes in the world.
