The 'Ben Lomond' is a variety of which fruit?

The blackcurrant, also known as black currant or cassis, is a deciduous shrub in the family 'Grossulariaceae' grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically.

Up until 1975 almost all commercial blackcurrants were the variety "Baldwin". Although tasty this variety was prone to late frosts and mildew.

In 1975 the variety Ben Lomond was introduced. With late flowering and (initially) resistance to mildew it was far better for commercial growers and amateur gardeners. One of its failings though is that it needs a hard winter to flourish and in many Southern areas of the UK this does not occur. Other "Ben" varieties have been introduced over the years. Some varieties are aimed principally at the commercial whilst others are intended for amateur gardeners.
