Description of the plant:
YOUNIQUE™ is a trade name of an attractive astilbe series from the Netherlands. Plants from this series excel in abundant flowering and healthy foliage. They are a cross between a.arendsii and a.japonica, bred by Jan Verschoor. YOUNIQUE™ Ruby Red brings shorter but intensely coloured plumes of rich ruby red colour. They bloom on 30-40 cm tall stems from mid June until midsummer unless tired by all-day sunlight. Leaves are rich green, divided, and healthy. Patented as PP23143 in 2012.Grow astilbe in humus-rich soil. If planted in boggy or regularly watered bed they can sit in full sun, too, otherwise choose a semi-shaded or shaded location. They are water loving plants and require a good dose of nutrients to look their best. They will not grow in chalky or clay soil that dries out in summer.
For best results divide the clumps every 3-4 years removing old and dead rhizomes in early spring. Also in the spring remove old leaves and last year’s flowers. If grown in poor soil you may need to cut back the entire plant after flowering to get rid of spent stems and tired foliage in order to encourage growth of new leaves. A dose of a liquid fertilizer is recommended. Fully hardy to about -34°C (USDA zone 4).
