Experience with buying plants and shrubs in Holland?

When comparing online between several shops. Sometimes there are up to 30% savings. Good quality is delivered by Baumschule Horstmann (also have grasses and co) Staudengärtnerei Gaißmayer Rosenhof Schultheis for roses Norma sometimes has pretty good plants for little money I could also imagine that nurseries and tree farms sell plants cheaper when the season (spring planting) is over. I don't know how they are open where you are. Here everything is and was closed and some are still sitting on goods.

Thank you for the hint.
When I know what I need, the comparison will be started.

Some have tiered pricing. It can be quite beneficial to take 5 of the same instead of 5 similar plants.

I have already ordered from Horstmann, good quality, everything has taken root. I also like Native-plants, so far everything has taken root there as well. As for the prices, no idea, price is not my main criterion when it comes to plants; I try to use mostly native species anyway. Preferably regional, so the plants are accustomed to the local climate, and even better organic, meaning grown without toxins.

I also find it very exciting. Nowadays, you can order and have everything delivered online.
