The rose bush received as a replacement under warranty appears healthy to me. Planted near a 'Tom Pouce' camellia, I am now waiting for it to take off... or not?

More information

This shrub rose is truly remarkable. Its single cup-shaped flowers have the ability to change colours throughout their long flowering season. In June, they bloom in red, but by September, they transform into an intense purple after passing through a pink phase. This selection is not only whimsical but also very easy to grow. It is a hardy plant with a graceful habit that looks wonderful in borders and flowering hedges.

Description

The Rosy Boom 'Colour Change' shrub rose is a low-maintenance and easy-to-grow bush rose with astonishing flowering that changes colour throughout the season. Its small, fragrant cup-shaped flowers with white centres and yellow stamens bloom in red in June, and over 100 days, they transition to pink and then intense violet. Its sturdy flower panicles are not afraid of rain. This hardy, healthy, and compact selection is easily pruned. It forms an upright bush with a flexible habit, suitable for planting in flower beds, small hedges, and containers, with a natural yet modern appearance reminiscent of wild roses.

The Rosy Boom 'Colour Change' shrub rose has a very flexible and bushy habit, reaching an average height of 1.40m (5ft) and a width of 60cm (24in) at maturity, making it ideal for small spaces. Its flowering is particularly abundant and regular from June to September as long as the soil remains moist. Its small, 4cm (2in)-wide roses are gathered in generous panicles. They have slightly flattened cup shapes and come in three different colours: red, pink, and intense violet. They have white centres and yellow stamens. The stems are adorned with deciduous foliage that is very healthy, consisting of leaflets with a smooth, satin-like finish. The growth of the shrub is slow.

Landscape roses are perfect for creating beautiful small hedges, planting them mixed along the edge of a terrace or in beds with small-sized shrubs. Combine them with abelias, nandinas, deciduous ceanothuses (pink or blue varieties), or caryopteris. They make great companions for peonies, paniculate phlox, and tall baby's breath. The modest size of Rosy Boom Colour Change allows it to fit in any garden, even small ones. It has versatile uses, depending on the preferences of each gardener: in a rose bed, alongside pink, red, or purple varieties such as Rhapsody in Blue, or mixed with easy-to-grow plants like perennial geraniums such as Rozanne, small-flowered carnations, perennial salvias, or pink and blue asters.

Planting and care

The Rose Rosy Boom 'Colour Change' is a low-maintenance flower that thrives in most regions except very hot ones. It is easy to care for, as it is not susceptible to diseases, cold or rain. Plant it in well-drained soil that has been prepared well and in a location that gets plenty of sun or partial shade. This rose is very hardy and can survive temperatures as low as -20°C (-4°F).

For best results, make sure the location gets sun for 4 to 5 hours every day, but not during the hottest part of the day or in strong winds. The soil should be loose, permeable, and nutrient-rich, but roses can adapt to any garden as long as the soil is well-prepared and rich enough. If you want to plant your rose in a pot, work the soil to a depth of 25 cm (10in) by crumbling it and adding a bottom amendment such as blood, fish, and bone. Position your plant, remove it from its pot, and cover the top of the root ball with 3 cm (1in) of soil. Backfill and water generously to eliminate air pockets. In dry weather, water regularly for a few weeks to help the roots develop. Also, use special rose fertiliser to stimulate plant flowering.

Roses may develop unsightly spots at the end of summer, but this is a natural occurrence and doesn't harm the rose's growth.
