F. J. Grootendorst  HRug. (de Goey; int. Grootendorst, 1918) is a depressing name which entered the rose world as "a Rugosa rose with the flowers of a red carnation", and that is an accurate description of a most adaptable and desirable hardy hybrid of the rugged Rugosa type.  It does keep blooming the whole season through, and it is so amenable to training that it can be had doing well at any height from three feet to six feet.  Its sport 'Pink Grootendorst" is just the same, save that the flowers are of a not quite agreeable but even pink.

Rosa rugosa and its hybrids.
...It would seem as though many of these Rugosa hybrids might be useful in producing new varieties of hardy roses. [...] For the convenience of those amateurs who are doing breeding work with roses, the pollen of the hybrids in the Arboretum's collection has been examined in the Cytological Laboratory.  In the following discussion the percentage of fertile pollen, as determined by microscopical examination, is reported for each hybrid where buds were available for study.
F. J. Grootendorst (R. rugosa X R. multiflora "Mme. Norbert Levavasseur").
Pollen less than 10% fertile.
A hardy, everblooming rose.  The flowers are small, very double, and with notched petals, giving the effect of a small red carnation.  They are fragrant and are borne in clusters all through the summer.  The foliage is dark green, rugose, and leathery.

Chester D. Wedrick.  Rugosa Roses and Their Hybrids.
F., J. Grootendorst is the first of a new type of Rugosa hybrid cross (Rugosa x Baby Rambler).  It is a splendid acquisition and of ironclad hardiness or it would never have survived the ordeal of bring christened with such a name.  Of vigorous, spreading habit, its thorny branches grow to a height of 6 feet or more with wonderful, large disease-free foliage.  It would be very ornamental even if it never bloomed, but covered as it is all season with its large clusters of small, bright red, double flowers with petals notched like carnations, it is a gem. The flowers are very durable, but scentless and sterile.  As an everblooming shrub or hedge of assured hardiness, it is equaled by no other plant I know, unless it is its pink form, a later introduction,which has all its virtues, but with flowers of a beautiful light shell-pink.  I am sure it will be a matter of only a few years until this type will be largely added to, and many new shades of color introduced.  At time of writing this (mid-November) they are both still blooming.

Shrub Roses
F. J. Grootendorst. (DeGoey, 1918.) Small, fringed flowers of bright red, produced in large clusters freely throughout the whole growing season. The plant is vigorous, up to 6 feet or more, with large, coarse foliage of superb quality.
Combines the flowers and everblooming habit of the Polyanthas with the Rugosa vigor. A most desirable shrub for specimens, or, kept about 4 feet high, it makes a fine everblooming hedge.
