The cultivar came out of a joint breeding programme run by Plant & Food Research in New Zealand and the Northwest Plant Company in the USA. It was selected in 2001 under the code 'NR7' from a cross between the unpatented New Zealand selection HR101 (seed parent) and the well-known cultivar 'Willamette' (pollen parent). In Europe and the United Kingdom it is sold as 'Ruby Beauty®', while in the USA and Canada it is known as 'Raspberry Shortcake®'. The licence is held by Pacific Berries LLC.

Plant and growth: the dwarf habit is genetically determined and stable. The plant grows slowly and reaches only 0.5 to 1 metre, most often 0.5–0.7 m in trials. The habit is compact and dense, the canes straight and upright, so the plant needs no support or tying in. The internodes are very short, typically 10–20 mm, and the canes are completely thornless. A single plant produces a large number of young canes, usually 20 to 50.

Fruit: medium to large, with an average weight of 3.9–4.7 g, which is more than some classic commercial cultivars such as 'Meeker'. The shape is oval to round and the colour light red. Compared with modern cultivars bred for shipping, the flesh is softer. The flavour is aromatic, with a lower sugar content of 8–9% Brix and moderate acidity of 2.1–2.2%.

Ripening and yield: a summer-bearing (floricane) cultivar that fruits on last year's wood. It ripens at a mid-early date, usually at the turn of July and August, and the picking season lasts around 30–32 days. Because of the dwarf habit the yield per plant is naturally lower – roughly 0.6–0.8 kg in trials, although according to the breeder a well-developed plant can produce up to 1.5 kg per season.

Hardiness and health: winter hardiness is average, quoted for USDA zone 7a, that is down to about −17 °C. In the cooler parts of Central Europe it therefore needs winter protection, or the containers should be moved into a cool but frost-free room. It shows resistance to raspberry bushy dwarf virus (RBDV) but is susceptible to mites.

The black raspberry (Rubus occidentalis) is still uncommon in European gardens, even though it is a botanically distinct species with its own flavour and composition. 'Selena' comes from Poland, where it was bred within a project co-financed from POIR funds. It was tested under the clone number NR 1825501 and filed for legal protection with the Polish COBORU office under number S 392.

Plant and growth: vigorous, with firm and stiff canes. The structure of the plant together with its smaller leaves makes picking easier. Compared with older black raspberry cultivars, 'Selena' has one major advantage – the canes carry only a limited number of thorns.

Fruit: large, with an average weight of 2.5 g, very glossy and well shaped, made up of small drupelets. The flesh is very firm. Sugar content is high, with Brix reaching 13.7%.

Ripening and yield: the cultivar is primocane-fruiting as well as floricane-fruiting – it bears on both last year's and this year's wood. The main crop on floricanes ripens from early to mid July, while the crop on primocanes starts ripening in early September. Picking is concentrated into a period of roughly five weeks. The average yield is 2.3 kg per plant.

Harvest and storage: the cultivar is expressly suited to machine harvesting. The fruit keeps a high post-harvest shelf life even after mechanical picking, which is decisive for industrial use.

Hardiness and health: in production trials the clone showed no cane damage from frost. It is highly tolerant of drought and of conditions with limited water supply. It has low susceptibility to aphids, to raspberry bushy dwarf virus (RBDV) and to fungal diseases of the canes and roots.

This Dutch cultivar, raised by the breeder Jan de Boer (Vitis-Idaea B.V.), is legally protected within the European Union under number EU 57353, and propagation without a licence is prohibited. The publisher of the cultivar is Plantipp / SAPHO.

Plant and growth: dwarf and compact, with moderate vigour. At maturity, roughly after ten years, it reaches a height of 1 to 1.5 m and a width of 0.75 to 1 m. The habit is dense and bushy, and the canes are almost thornless.

Foliage: the most striking feature of the cultivar. At bud break in spring the leaves are orange-yellow, turning to a bright golden and light yellow-green in summer. Unlike many other plants with yellow foliage, the leaves of 'Groovy®' do not scorch in full sun.

Fruit: large, 2–3 cm across, bright red, creating a striking contrast with the golden foliage. The flavour is sweet, juicy and aromatic.

Ripening and yield: it is classified primarily as a summer-bearing, non-remontant cultivar that fruits on one-year-old canes. Under favourable conditions, however, the cropping period extends and fruit forms as soon as new canes develop. Picking runs from late June into September. The cultivar is productive and crops in the first year after planting.

Hardiness and site: winter hardiness is exceptionally high, withstanding frost down to −35 °C without damage. It prefers full sun to partial shade and a fertile, humus-rich, moist but well-drained soil.

Pruning: maintenance is very undemanding. At the end of winter or in early spring, the spent, dry canes should be cut back to ground level. For optimal growth, 7 to 10 young canes per running metre should be retained.

This cultivar, also known under the breeder's name 'Hararasp', belongs to the Korean raspberry (Rubus crataegifolius), a different botanical species from the common European and American raspberries (Rubus idaeus). It comes from Japan, from the breeder Toshikhiko Hara, and is legally protected.

Plant and growth: the most interesting feature of the cultivar. The plant forms thick, overwintering stems that can be trained into an upright small tree with a strong central trunk and a crown of fruiting branches. Growth is compact and narrow – it reaches a height of 175 to 200 cm and a width of only 60 to 100 cm. Thanks to the firm, stiff canes it needs no support or tying in whatsoever. The canes are covered with small thorns.

Flowering: from April to May, with white flowers that are very attractive to bees and butterflies.

Fruit: small, about 2 cm across, spherical and intensely red. Unlike ordinary, often matt raspberries, the fruit has a remarkably glossy surface. The flavour is good.

Ripening and yield: a summer-bearing cultivar that fruits on last year's wood. It ripens early and has a very long picking season, cropping continuously throughout the summer from June until August. It bears heavily and regularly every year, and the tree-like shape makes the fruit easy to reach.

Hardiness and site: it withstands frost down to −25 °C and shows excellent tolerance of heat and drought. It is disease resistant. It prefers full sun or partial shade and a fertile, well-drained soil.
