‘Roseberry’ plants are hardy and survived each winter during the test period with no damage when protected by 10 cm of straw cover. The pink-flowering cultivars ‘Serenata’ and ‘Viva Rosa’ used as controls often did not survive the winter conditions and usually had to be replanted each year. ‘Roseberry’ plants are very vigorous with a spreading habit. They produce multiple crowns and few (3) stolons in the first year of growth but medium (5) number of stolons are produced in the second and subsequent years, many (7) for Rosalyne. The stolons tend to produce flowers and fruits before rooting. roseberry

The leaves are made up of three leaflets, the surface is medium green, interveinal blistering is weak. Petioles are medium long with slightly outward hairs. The terminal leaflets are concave, much longer than broad with serrated to crenated margins and an obtuse base. The plants are less susceptible to leaf spot (Mycosphaerella fragariae (Tul.) Lindau) and leaf scorch (Diplocarpon earliana (Ell. & Ev.) Wolf) compared to ‘Rosalyne’ but this does not seem to weaken the plants or reduce their attractiveness.

Flower production starts in early July during the first year of growth and by mid- May to early June the following and subsequent years. Flowering is continuous during the summer and lasts until the first frosts in fall. The inflorescences show many flowers and are placed at or above canopy. The flowers have 5-7 petals while normally 5 are typical of Fragaria. They are large (2.74 cm in diameter) compared to Rosalyne (2.12 cm) with a corolla that is larger than the calyx. The petals are overlapping and broader than long and mainly dark pink on the surface (Royal Horticultural Society (1995), red-purple group 67C compared to those of Rosalyne, group 67D.
The fruits start ripening about the third week in June, same as for ‘Rosalyne’
The fruits are dark red, moderately glossy and globose with some ridges. The fruit is large (9g) while it is small (1.5g) for Rosalyne, the calyx segments are outwards to downwards, the achenes are levelled with the surface and the calyx is hard to hull. 10-20% of the flesh is medium red while the balance is white. It is a bit soft like Rosalyne but has an excellent, very aromatic flavour with medium sugar and acidity.

‘Roseberry’ strawberry is a wonderful variety for home gardeners who will get a continuous show of flowers all summer long in the garden accompanied by the production of very tasty fruits. It is especially recommended for use in hanging baskets because the stolons flower and fruit before rooting and they don’t break under a high fruit load.
