Rosa Grandiflora: what it is, as well as a description of the varieties and their photos, a comparative table with other types of plants, flower care

Many beginner amateur gardeners dream of planting fragrant rose bushes in their garden, but do not know how to choose unpretentious and resistant to diseases and frosts among the variety of varieties. It is worth paying attention to the relatively young group of roses - grandiflora. To do this, we suggest that you familiarize yourself with the photo and description of this variety. In the article we will tell you how Grandiflora roses differ from other types of flowers, and what features of growing and caring for this variety.

What it is?

Grandiflora is an arbitrary garden group of roses, unrecognized in many European countries, but is actively used by breeders of Russia and the United States to breed new varieties.

This type of rose appeared in the mid-twentieth century in the USA. when crossing floribunda roses and hybrid tea. The resulting hybrid inherited the best qualities from its ancestors:

large double flowers, collected in inflorescences of 3-5 buds or single, with a delicate aroma or not smelling at all;
tall bush with powerful long spreading stems;
differs in long continuous flowering, frost resistance and resistance to fungal diseases.

Grandiflora propagated by cuttings and grafting.

Features of cultivation and differences in care from other species

Grandiflora like any rose loves light and does not tolerate drafts and high humidity, therefore, it is better to grow the queen of flowers on the sunny side of the site, protected from the wind, in well-drained soil. Seedlings are planted in well-heated soil in late spring. For lush flowering, it is necessary to feed the rose periodically: in the spring, when buds are formed and in the summer during budding.

It is not necessary to do top dressing in the fall so that new shoots do not form before frosts. A weekly morning and evening watering of the bushes is required. Water should be poured under the root to prevent leaf burns. If the summer is dry, then water the bushes should be twice as often. During the day, it is impossible to water the prickly beauty, so as not to burn the roots in the heated ground. To access the root system to oxygen, it is necessary to loosen and mulch the soil.

You can increase the number of shoots and leaves if you cut the first buds. Periodic pruning is also necessary for bush formation. They usually shelter for the winter, but there are varieties that do not require shelter.

Caring for floribunda is the same as for grandiflora.
A climbing (winding) rose, unlike grandiflora, needs support for growth. For the winter, shoots must be removed from the support.
Rosa Patio, unlike grandiflora, can be grown not only in the open ground, but also as a houseplant in the house, as well as outdoors in pots.
Growing, as well as caring for a scrub rose is not very different from caring for grandiflora, but the bush should be pruned moderately. Grandiflora is pruned harder.
Hybrid tea, unlike grandiflora, is very moody in leaving. She is afraid of cold weather, is often affected by powdery mildew, and may die from improper care. It should be fed carefully, strictly according to the instructions, more often than grandiflora treated with insecticides and fungicides; water less often than grandiflora.
A miniature rose, unlike grandiflora, is most often planted as a houseplant, but in the garden it is also found in border compositions. When planting in open ground, it is sheltered to protect thin weak stems from direct sunlight, and grandiflora does not need shelter. There are differences in watering: they are watered by the method of sprinkling, trying not to flood the root system. In this way, you can’t water the grandiflora - brown spots will appear on the leaves, so watering is carried out only under the root.
