Rubus Tayberry, is a cross between the raspberry and blackberry. The fruit is dark red in colour and longer than a raspberry. Tayberries are juicier than raspberries, and ripen over a many weeks in July and August. They are best when allowed to fully ripen to a dark red colour before picking, rather like mulberries. Mine don't really last long enough on the canes to fully darken, as the resident blackbird population decimates it each year, invariably first thing in the morning just after the dawn chorus. I don't really mind, as I love the blackbirds. So does the cat that's just moved into the neighbourhood, judging by the bits of blackbird under the canes this morning. I shall sit here, silently, and wait.
