Roses In Alphabetical Order ‘I’

‘Iceberg’ Roses (Floribunda, Introduced – 1958)One of the most cold tolerant of the floribundas, this rose also performs well in the South, though a slight susceptibility to blackspot makes it less than an ideal choice for the Southeast. In the drier Southwest, however, ‘Iceberg’ is one of the half dozen roses he recommends most highly as both easy and rewarding. Wherever you garden, the abundance and beauty of its blooms are likely to make ‘Iceberg’ irresistible. The double (30 petals), 3 in (7 .6 cm) flowers are pure white, very fragrant, and held in clusters above the semi- glossy, light green foliage. ‘Iceberg’ makes an excellent plant for a winter-hardy hedge that will continue to bloom from late spring to fall -and into the winter in the South.
‘Illusion’ Roses (Shrub, Introduced – 1961)Another good shrub for the north country, ‘Illusion’ bears bunches of medium-size, lightly fragrant, double, red flowers in early summer. After re-blooming moderately in midsummer, this rose starts flowering heavily again at summer’s end and into the fall. Nurseryman Wilhelm Kordes bred this from two exceptionally hardy and disease-resistant species. In the warmer part of Connecticut range, ‘Illusion’ develops long, flexible canes that can be trained along a fence or up a trellis.
‘Immensee’ Roses (Shrub, Introduced – 1982)The small flowers of ‘Immensee’ are pale pink to almost white, single, and quite fragrant. The blooms appear in profusion in the spring and repeat well throughout the season. The leaves are small in proportion to the flowers and are dark green and glossy.
This rose has a low-growing, spreading habit; canes may spread as wide as 13 feet. This rose is useful as a flowering ground cover. This rose, bred by Kordes of Germany using R. wichuraiana, is very hardy and resistant to disease.
‘Impatient’ Roses (Floribunda, Introduced – 1984)This variety’s name was intended to imply that the plant was impatient to re-bloom, but gardeners have found that they grow impatient waiting for it, as its repeat interval is long. The high-centered, slightly fragrant flowers are bright orange with a yellow base. The 3-inch blooms with 20 to 30 petals appear singly or in small sprays. Very thorny canes are covered with semi-glossy dark green to mahogany leaves that resist disease. Plants grow 2 to 3 1/2 feet tall.
‘Independence’ Roses (Floribunda, Introduced – 1951)The brilliant orange-red blossoms of ‘Independence’ make a dramatic contrast to the bronze-purple color of the new growth, and the 4 1/2 in (11 cm) fragrant double flowers continue to show up well against the dark, glossy green of the mature leaves. Although the flowering may be more intermittent than that of other floribundas, this rose mounts a fine display when it does bloom, bearing its large and shapely blossoms in bunches of as many as 10 per cluster. The provenance of this rose is significant. This rose was bred by the German nurseryman Wilhelm Kordes, a master rosarian whose name is synonymous with hardy and healthy shrubs.
‘Ingrid Bergman’ Roses (Hybrid Tea, Introduced – 1983)This rose commemorating the late Swedish-born actress has slightly fragrant blooms of dark red set off by dark green foliage. Flowers have 35 to 40 petals and open 4 to 5 1/2 inches across. The most outstanding feature of this rose is its exceptional winter hardiness. Upright plants grow 4 1/2 feet tall.
‘Intrigue’ Roses (Floribunda, Introduced – 1984)Intriguing it is, for there are few roses with this medium purple to plum color overcast with gray. The strongly fragrant blooms start out high-centered, then open into decorative ruffled flowers 3 inches across that have 20 petals. Shiny medium to dark green foliage covers thorny canes. The compact plants grow only 1 to 2 feet tall, making this variety good for edging. Blooming does not repeat very quickly.
‘Irish Gold’ Roses (Hybrid Tea, Introduced – 1966)Known in Europe as ‘Grandpa Dickson’ (after a patriarch of the Northern Ireland rose breeding clan), ‘Irish Gold’ rose has clear, pale yellow flowers whose petals quill when the flower is open, giving it a star-shaped outline. Occasionally the petals have a pale pink edge. Flowers are 5 to 6 inches across with 30 to 35 petals, and have a light, sweet fragrance. The bushy plants reach a height of 3 to 4 1/2 feet and have leathery, glossy, dark green foliage.
‘Irresistible’ Roses (Miniature, Introduced – 1989)The perfectly formed double flowers of ‘Irresistible’ rose are white with a pale pink center and are produced on long stems. Borne singly and in clusters, the high-centered blooms have more than 40 petals each and put off a moderate, spicy fragrance. Hips are green to yellow brown, and leaves are medium green and semi- glossy.
Plants are upright and larger than most miniatures. They are well suited to growing in beds, borders, and containers. Their abundant production of long-stemmed hybrid-tea-type blooms makes them ideal for flower cutting and exhibiting.
‘Isabella Sprunt’ Roses (Tea, Introduced – 1855)This rose is a “sport” of the classic tea rose ‘Safrano’, which means that a bud on a bush of ‘Safrano’ spontaneously mutated, and a branch with different characteristics emerged from the parent bush. A nurseryman observed this and took a cutting from the mutated branch. Every bush of ‘Isabella Sprunt’ descends from that cutting.
Aside from that, every bush of ‘Isabella Sprunt’ is also a handsome shrub, mounded and as broad as it is tall, with dean, healthy foliage that is plum purple when new. This rose is almost always in bloom, bearing sulfur yellow, semi double, fragrant flowers that, not surprisingly, resemble those of its parent in everything but color.
‘Ispahan’ Roses (Damask, Introduced – 1832)The very fragrant, double blooms of ‘Ispahan’ (also called ‘Pompon des Princes’) appear in profusion over a 2- month period in early and mid-season, but they do not repeat. Borne in clusters, the bright clear pink flowers are 2 1/2 to 3 inches across, cup shaped, and loosely re-flexing. They are long-lasting, holding both their shape and their color well. Foliage is small with a blue-green cast.
This rose is bushy and upright. With a flowering season that is remarkably long for a damask, this rose is valued both as a garden shrub and for cut flowers. The plant is vigorous, disease resistant, and quite hardy.
‘Ivory Fashion’ Roses (Floribunda, Introduced – 1958)The long-lasting, creamy white flowers of ‘Ivory Fashion’ rose begin as rounded buds suffused with yellow and peach. These open into flat, fragrant 3 1/2- to 4-inch flowers with 15 to 18 petals that bloom in sprays all summer. Plants grow 3 1/2 to 4 feet tall, with leathery, medium green, semi-glossy foliage on almost thorn-less canes.
