90 days, indeterminate
— The regular-leaf plants of 'King Humbert' are productive and vigorous, but fairly compact for an indeterminate variety. Its fruits are a blocky, elongated plum-shaped, red colored, two to three ounce, paste-type tomatoes borne in clusters. They are meaty but are pleasantly juicy and deliver an interesting, slightly sweet, mild flavor.
They are good for drying or sauces, yet quite suitable for fresh eating. It does well both in the ground as it does in a greenhouse.
Introduced by the W. Atlee Burpee & Company
in their 1884 seed catalog.
They described it as follows:
"This new Tomato, which we secured the past summer from an Italian grower, will prove of value to family gardens. It is pear-shaped, 2 to 2-1/2 inches long, by 1-1/4 to 1-1/2 inches wide, and of a beautiful rich red color, with very few seeds ; they grow 6 to 8 fruits in a cluster."
It was also described in 1885 by Vilmorin-Andrieux. Over the decades, it has been sold as 'Roi Humbert', 'King Umberto', and 'Re Umberto', which are merely the same name in various languages honoring Umberto I, who became King of Italy in 1878.
