[From "Journal of a Horticultural Tour through some parts of Flanders, Holland, and the North of France, in the Autumn of 1817", by Patrick Neill, p.p. 187-188:] Aug. 30.—We next morning visited the flower-garden and nurseries of Mynheer Voorhelm, a name usually associated by English tourists, who have visited Haarlem, with that of Van Eeden, and equally celebrated for a hundred years past, the present florist being the grandson of him who is so often mentioned in Justice's "Scots Gardener,”—an excellent and original work, published at Edinburgh about the middle of the last century. We found Mr Voorhelm's collection of bulbs to be very considerable; but not superior to some others in the immediate neighbourhood. Among the greatest rarities in his garden were seedling plants of the Stone Pine-tree, (Pinus Pinea), raised from large cones which he had procured from Italy, where the kernels are often served up in the dessert the stone-pine, it must be understood, is really an uncommon plant in Holland. We observed a pear-tree,bearing abundance of fine fruit, not of an appearance. familiar to us: Mr Voorhelm called it the Wygen-pear, and recommended it as an excellent table fruit, for the months of September and October.

Leaving these museums, we again bent our steps to the region of bloemistries, near the Wood of Haarlem. .... we were politely received by Mr Schneevogt, formerly a partner of Mr Voorhelm ; and as soon as he perceived that we possessed some knowledge of plants and fruits, and took an interest in his collection, he invited us to inspect the whole, and gave us every explanation we required.
This seemed to us to be one of the most extensive and best managed flower-gardens of Haarlem. In some of the others which we had visited, there was an appearance of narrowness or poverty; but here all the arrangements were on a liberal scale. The flower-bulbs were exceedingly numerous, and were to be seen almost at one view in a handsome store-room. The glazed houses and frames were neatly kept; there was, however, nothing peculiar in their structure, excepting that, in the hot-house, the covers of the flues were of iron.... Mr Schneevogt invited us into his house, and shewed us a part of his botanical and horticultural library, which we found to be rich in German publications that are little known to the gardeners and orchardists of Scotland. We had the satisfaction, in particular, to see the extensive periodical work of J. B. Sickler, of which twenty-two volumes in octavo were published between 1794 and 1804, under the title of "Teutsche Obstgärtner." At this period, Mr Sickler changed the form and title of his publication; and, under the name of " Allgemeines Teutsch-garten Magazin," eight successive volumes in quarto came out; when the great war, which agitated the whole of Europe, oceasioned the discontinuance of this useful work.
[From "Rose Breeding before 1800 in Germany", by Anita Böhm-Krutzinna, 2017, p.5:] The gardeners Jean Kreps and Gottfried Voorhelm offered some of their roses with made-up French names...... Voorhelm moreover sold his range to the French gardener François from Paris
