This is a Dutch web site. With some patience, even if you don’t read Dutch (I don’t), you will be able to find vegetable cultivars that are not familiar. The site, though in Dutch, is indexed by Dutch, English, and Latin plant names. Between a combination of these languages you ought to be able to find your way around. If you want to read the plant description, then cut and paste it into the Google Translate utility. The English comes out a bit confused, but legible, as in this example for a dark colored pepper:
Growing in the greenhouse or outside in warm sheltered place. Outside before the end of May Driving distance ± 1 m in the row 50 cm. How is it that brown fruits once the word “chocolate” elicit? Well, this funny little peppers’ll go for chocolates! A welcome addition to the color palette.
The Dutch, of course, have been famed market gardeners for centuries. They are also famed for growing in greenhouses. I always find it ironic that in January, in my California groceries, the red peppers are from the Netherlands. For home vegetable gardening and for greenhouse gardening you will find something in this catalog that will tempt you. If the Vreeken’s Zaden shopping cart confuses you, then call the company. You will find a phone number in the “contact” section. You can assume that everyone in the office speaks English. Check the local time in the Netherlands before calling. The contacts page lists the phone number, office hours and the email address.
