Lonicera ×americana (Miller) K. Koch

A climbing semi-evergreen shrub. Leaves obovate, short stalked or sessile, dark green; the uppermost pairs of leaves connate. Inflorences in terminal spikes, often in groups of three; corolla 4-6 cm long, purple, inside white, ageing to yellow, scented. Fruits: none; a sterile hybrid.
This is one of the most lovely honeysuckles with a very long flowering period, from June to the end of October, or even up to the first frost.
It is worthy of much more extensive planting than at present and it is incomprehensible that nurseryman do not cultivate this honeysuckle in great numbers!
