​Our Incredible International History

The Company was founded by William Van De Zwaan in 1990. William had spent his entire life in the horticulture industry. Raised in the famous Van De Zwaan rose production glasshouses. The Van De Zwaan roses were world famous for incredible quality and aroma. Even the Pope wrote a decree thanking them for supplying the Vatican and providing distinction for their unique carnations!

We’ve moved our mixing and bottling facilities from Holland to Humboldt County, California. Which combined Dutch craftsmanship with Humboldt’s gardening prowess and knowledge. Making it the next chapter in the continuing legacy of H&G Premium Nutrients and Additives.
