How SAART™ Seeds Are Bred
Flower Breeding at SAART™ – On Zinnias, Dahlias, and Conscious Selection.
I do not breed flowers with the goal of maximum uniformity, but out of an interest in diversity, development, and adaptation.
At SAART™, zinnias and dahlias emerge from my own selection work, observed over several years and continuously re-evaluated.
Not every beautiful bloom is propagated further, and not every line is maintained.
For me, breeding means selection – in the field, over the course of the season, and in the way genetic diversity is handled.
Location, climate, and soil along the Saar play just as important a role as the specific breeding goal.
This page describes how I work with zinnias and dahlias, why conscious selection matters more than uniformity, and why variation is not a flaw but an integral part of the process.
Origin and Location
My breeding work does not take place in an abstract space, but in a very specific location.
The plants I work with grow in Kanzem along the Saar – on soils that are not standardised and under weather conditions that vary significantly from year to year.
These conditions influence growth, flowering behaviour, and vitality far more than catalogue descriptions might suggest.
Rather than adapting plants to idealised conditions, I observe which individuals assert themselves under the given circumstances.
Selection here does not mean optimisation toward perfection, but choosing plants based on adaptability, stability, and development over several years.
The location is therefore not a backdrop, but an active part of every breeding decision.
Open Pollination & Genetic Diversity
Zinnias and dahlias cannot meaningfully be reduced to complete uniformity.
A large part of my work is based on open pollination, as it preserves genetic diversity and makes development possible in the first place.
Open pollination does not mean randomness, but a controlled framework in which traits can appear, shift, or stabilise.
Within this diversity, I observe flower form, growth habit, vitality, and stability over multiple generations.
Variation is not a mistake, but an indicator of genetic potential.
Uniformity does not arise from eliminating variation, but from repeated selection under real growing conditions.
Especially with zinnias, diversity is a prerequisite for resilient lines that can adapt to changing years and locations.
Selection in the Field
Selection does not happen at a desk, but in the field.
Over the course of the season, I observe each line repeatedly: during early growth, throughout flowering, and into seed maturity or tuber formation.
What matters is not a single spectacular bloom, but the overall performance of the plant.
Growth habit, stability, health, and flowering consistency carry more weight than colour or form alone.
Plants that only perform under optimal conditions are not propagated further.
Those that remain are plants that show stability over weeks and remain viable under changing weather conditions.
In this context, selection means restraint: not everything that is beautiful is kept.
What Breeding Means – and What It Does Not
For me, breeding does not mean guaranteeing results or promising repeatability.
Plants respond to location, weather, and care – even when they come from the same line.
Variation is part of the process and not a deficiency, but an expression of living development.
Anyone working with my zinnias or dahlias is working with genetic material, not standardised products.
This openness requires attention, observation, and a willingness to engage with differences.
Breeding is not a promise of uniformity, but an invitation to accompany development.
