Crataego-Mespilus Dardari

This is a graft hybrid between Crataegus and Mespilus, sometimes reverting in growth to one of the parents. White flowers.

Cytisus

The interesting hybrid Dallimorei, raised by crossing C. albus and C. scoparius Andréanus at Kew, was put in commerce in the autumn of 1912. It is of dense habit, has small trifoliate leaves, and is covered with rosy mauve flowers in late spring. C. Beani is of rambling habit with yellow flowers. The modern forms of scoparius, such as Butterfly, which may be succinctly described as a pale Andréanus; and Daisy Hill, chocolate on blush ground, will not be overlooked by shrub-lovers. All make good standards, in common with most of the Brooms.

Daphne

A dwarf evergreen species named retusa, with shining leaves and fragrant white flowers suffused with rose in terminal umbels in May, has been introduced. See the Botanical Magazine, T. 8430.

Davidia

Involucrata, a Chinese tree with Limelike dark green serrate leaves, growing up to thirty feet high, ornamental by reason of its white bracts, flowered for the first time in England in 1911 from seed sent from China by Wilson and sown in 1901. It bears round fruit about as large as a walnut. The inflorescence is drooping and comes from side spurs. Of the two large bracts, one is nearly double the size of the other. In China the trees grow up to fifty feet high. It is quite hardy.
