Clematis macropetala 'Ola Howells' was bred by the British team of J Howells and W Snoeijer and introduced in 1999. Its double, nodding, bell-shaped flowers appear in a rich violet-blue: four elliptical, pointed sepals surround violet-blue staminodes and creamy stamens, with a flower diameter of 6-7 cm.
Reaching around 300 cm in height, 'Ola Howells' flowers from April to May on trellises, trellage and obelisks; it also does well in a large container. As an early-flowering variety, it suits smaller gardens and adds colour to the garden early in the year.
'Ola Howells' is very hardy (zone 5, down to about -28.8 °C) and easy to maintain: cut the plant back to around 100 cm after flowering in June, so it stays compact and flowers abundantly again the following year.
