"Bramble" is the common name for the genus Rubus which includes raspberries, blackberries and their hybrids and cultivars.
Rubus phoenicolasius (Japanese wineberry, [2] wine raspberry, [3] wineberry or dewberry) is an Asian species of raspberry (Rubus subgenus Idaeobatus) in the rose family, native to China, Japan, and Korea. The species was introduced to Europe and North America as an ornamental plant and for its potential in breeding hybrid raspberries.
The yellow Himalayan raspberry is a threat to native flora because it can outcompete other plants. More specifically, it has higher photosynthetic rates, higher nitrogen fixation rates, and therefore a higher photosynthetic nitrogen use efficiency (or PNUE). [17] The yellow Himalayan raspberry is currently only invasive on Hawaii. [12]
Renewal pruning. Spur pruning: Spur bearing varieties form spurs naturally, but spur growth can also be induced. Renewal pruning: This also depends on the tendency of many apple and pear trees to form flower buds on unpruned two-year-old laterals. It is a technique best used for the strong laterals on the outer part of the tree where there is ...
[35] [36] Yellow raspberries and others with pale-colored fruits are lower in anthocyanin content. [35] Both yellow and red raspberries contain carotenoids, mostly lutein esters, but these are masked by anthocyanins in red raspberries. [37] Raspberry compounds are under preliminary research for their potential to affect human health. [38]
Rubus spectabilis is a deciduous, rhizomatous shrub growing to 1–4 metres (3.3–13.1 feet) tall and 9 m (30 ft) wide, with a moderate growth rate of 0.3–0.6 m (12–24 inches) per year.
Like raspberries, it is not a true berry, but instead an aggregate fruit of numerous drupelets around a central core. The drupelets may be carefully removed intact, separately from the core, when picked, leaving a hollow fruit which bears a resemblance to a thimble , perhaps giving the plant its name.
Rubus leucodermis is a deciduous shrub growing to 0.5–2.5 metres (1 + 1 ⁄ 2 –8 feet), with prickly shoots. [5] While the crown is perennial, the canes are biennial, growing vegetatively one year, flowering and fruiting the second, and then dying.
