Miniature rose plant named ‘SAVathoughts’

Abstract

‘SAVathougths’ is a new and distinct variety of miniature rose plant, primarily identified by it's semi-double, bright orange flowers with orange-red edges and accents when grown in full sunlight. Flowers gradually fade to a complimentary yellow with lighter red accents, giving the appearance of orange and yellow flowers, all edged with red, on the plant at the same time. This plant will grow and bloom satisfactorily both in the greenhouse and outdoors, in the ground or in containers, providing bright decoration. Disease resistance has been shown to be outstanding for this rose in both California and Massachusetts.

Description

CROSS REFERENCE

This new invention may be compared to ‘SAVaworry’ (U.S. Plant. Pat. No. 17,787) from this same breeding program. The plant habit of ‘SAVaworry’ and this new invention is low and somewhat spreading, becoming wider than tall, and with pinnately compound leaves having 5 to 7 leaflets. Both cultivars may, at times, have just 12 petals. The flowers of both cultivars, when full open, are yellow and have red along the outer margins of the petals that is enhanced by the sun.

The lineage of these plants can be traced back to ‘Little Darling’ (U.S. Plant Pat. No. 1,581) which is found in the third generation for ‘SAVaworry’ and the fourth generation for this new invention; and to Rise ‘n’ Shine (U.S. Plant Pat. No. 4,231) in the fourth generation of the new invention and ‘MORsherri’ U.S. Plant Pat. No. 3,826) in the third generation of this new invention, both of which are in the third generation of ‘SAVaworry’.

The differences between these two cultivars may first be seen in the flower. The flowers of ‘SAVaworry’ are a straw- to lemon-yellow and only the borders of the outer margins of the petals becoming an orange-red in the sun. The flowers of this new invention are a yellow-orange with red borders and accents on the petals in the sun. The foliage on this new invention is primarily 5-leaflet leaves with 7-leaflet leaves while the foliage on ‘SAVaworry’ is primarily 7-leaflet leaves with some 5-leaflet leaves.

Genus and species: Rosa hybrida.

Varietal denomination: ‘SAVathoughts’.

BACKGROUND OF THE INVENTION

This present invention relates to a new and distinct variety of hardy, bush type plant of the miniature rose class. This variety was created by myself, Wendy R. White, under controlled conditions in a greenhouse in Rowley, Mass., by crossing the following two rose plants:

• • The seed parent is an unnamed, unpatented and unintroduced miniature seedling with orange-red flowers which was created from this same breeding program by crossing ‘ROzorina’ (U.S. Plant Pat. No. 2,321) by ‘Baby Katie’ U.S. Plant Pat. No. 4,471).
  • The pollen parent is an unnamed, unpatented and unintroduced miniature seedling with pale apricot-pink flowers, also from this same breeding program, created by crossing ‘LAVjune’ (U.S. Plant Pat. No. 6,859) by ‘MACgenev’ (U.S. Plant Pat. No. 8,279).

The idyllic goals of this breeding program were to create unique miniature roses with the qualities of exhibition, hybrid tea form blooms born in abundance from late spring to late fall on vigorous, well-branched and compact plants, with hardiness, disease resistance and fragrance. For this particular cross, the cultivar chosen as seed parent was known for its above average production of hybrid tea form blooms with moderate fragrance born on a vigorous, well-branched and compact plant. The cultivar chosen as pollen parent was known for exhibition, hybrid tea form blooms with mild fragrance born a compact plant. Neither parent had been fully evaluated for disease resistance or hardiness. The resulting new cultivar shows a combination of traits passed down through both parents. Its primary color appears to be from ‘LAVjune’. The color of its flushing in full sunlight appears to be from ‘ROzorina’. The shape of the leaflets and the leaflet count per leaf seems to be from ‘Baby Katie’. The plant height of the new cultivar is the same as its pollen parent, about 10-inches, however, its pollen parent is very upright, only becoming 10-inches wide and the new cultivar may be up to 20 inches wide. The new cultivar has fewer petals than either parent, and its flowers are of a different color than those of either parent.

Asexual reproduction by cuttings of this new cultivar in Rowley, Mass., and Arroyo Grande, Calif., shows that all distinguishing characteristics of this rose continually come true to form.

BRIEF SUMMARY OF THE INVENTION

The present invention relates to a new, distinct and low growing variety of hardy, bush type, miniature rose plant, which is primarily characterized by its semi-double, bright yellow-orange flowers, edged and accented with red when grown in full sun. Other characteristics distinguishing it from all other varieties of which I am aware are its low-growing, upright yet spreading plant habit and the strength of its canes, and its high resistance to diseases. The variety is further characterized by:

• • Flowers borne mostly singly
  • Dark green, semi-glossy foliage
  • Repeat blooming habit from late spring to late fall
  • A moderate number of thorns
  • Easy to propagate from soft wood cuttings
  • A plant that grows and blooms satisfactorily both in the greenhouse and outdoors, providing decoration in the garden or containers.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations, measurements, values and comparisons describe plants of the miniature rose class of Rosa hybrida, ‘SAVathougths’, at 8 to 12 months old, growing in 3½-inch plastic pots, in a growing medium of peat moss and coconut bark, growing outside in Essex County, Mass. and a 6-year old plant growing in the ground for four years in Esex County, Mass. No significant difference was found between plants grown in pots compared to the one in the ground. A detailed descripton is presented here in outline form. Color references are made using The Royal Horticultural Society Colour Chart except where common terms of color are used. Phenotypic expression varies with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.
