Description
Alstroemeria ‘Summer Rose’ brings its superb fresh pink hue accentuated with yellow to this excellent line of hybrids capable of surviving occasional frosts down to -12/-15°C. Well-suited to outdoor cultivation, this variety also makes a striking impact in pots and bouquets. The plant flowers generously for several months between May-June and October.
Alstroemeria ‘Summer Rose’ is a recent hybrid variety, developed in the Netherlands by HilverdaFlorist. It is the result of cross-breeding between varieties intended for cut flowers and dwarf varieties. This is a plant with sturdy stems and vibrant colours, ideal for the garden and floral arrangements.
‘Summer Rose’ shows good hardiness. The plant forms a bushy clump of 60-70 cm in height when in flower, with a spread of 50 cm. Flowering occurs from May-June to October-November. The very open flowers are gathered in small clusters at the ends of the stems. They consist of 3 small central, fresh pink petals with a yellow base streaked with brown, surrounded by 3 broader petals of the same pink. The foliage is arranged towards the upper part of the stems. The leaves of this variety are a very fresh light green shade, in perfect harmony with the flowering. Foliage and stems disappear in winter, leaving only the underground running crown with fleshy roots. It is sensitive to transplant shock, especially in older plants, so it is best to avoid moving it once established.
Alstroemeria 'Summer Rose’ is an excellent variety for outdoor planting. This perennial is stunning in flower beds or on a slope which is slightly shaded in the afternoon. Pair it with short ornamental grasses and compact daylilies like 'Everydaylily Rose', for example. Container cultivation is also possible, and you can cut a few stems to create opulent bouquets.
Note: Please be aware, our plug plants are products intended for experienced gardeners: upon receipt, transplant and store them under cover (conservatory, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before planting them outdoors once the risk of frost has completely passed.

View all →Planting and care
Alstroemeria Summer Rose should be planted in spring, choosing a spot with morning sun or partial shade, in light, well-drained, well-worked soil with a sandy or loamy texture, low in lime, neutral to slightly acidic, and not overly fertile. While they appreciate some moisture to support their flowering, they adapt quite well to dry soils in summer. These plants are fairly hardy provided the soil does not remain waterlogged in winter. You can protect the crown with a thick mulch of leaves or fern fronds in autumn. Slugs are particularly fond of young shoots, so take care to protect them.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
