Arboretum and Nursery

Ecological and evolutionary basis

The resiliance of reliably climate resistant species in the temperate climate is based on three factors.

One of them is that, having adapted through long time in earlier periods of Earth history, they

developed the necessary biochemical mechanisms programmed genetically. Therefore, they can survive extremities with good efficiency.

Long drought, extraordinary heat, extreme cold, thunderous winds and the worst combinations of the above, can be tolerated only by those plants, which are the survivors of the evolutionary "drill" of millions of years. That is why in Central Europe we could introduce species which proved to be totally winter hardy and climate resistant, despite the fact that they experience in general notably less irritation at their present living areas - such as Arizona, California, Chile, the Mediterranium or the Himalayas - than here.

Besides the climatic-evolutionary factor, it is the method of raising plants, the technology of growing, and the conditions after planting to the final location, that are important.

In spite of the genetic-biochemical conditions, a plant might become more frost sensitive and generally weaker if - compared to its original living area - it receives too much watering or nutrition, but on the contrary, its needs of light and temperature are not satisfied. The technologies of profit-oriented nurseries make plants vulnerable and live shorter: they become goods "inflated" in a hurry, with a fast mortality.

Our products are slower, but tougher and more durable plants.

The third factor contributing to increasing climate resistance in the case of more sensitive species is selection: choosing individuals (clones) from a wide population, which are more (preferably much more) climate resistant than the average of the species.

Resolutely applying all the three factors, in the gardens and the arboretum designed and built by us, we succeeded to supply species and cultivars which are rarely or never sold in Hungarian nursery gardens.
