Other Uses

Can be used as a ground cover plant in a sunny position[188]. They can be allowed to scramble on the ground and will form an effective ground cover, rooting at intervals along the branches[208]. They should be planted about 2.5 metres apart each way[208]. The form C. radicans f. flava has gained the Royal Horticultural Society's Award of Garden Merit.

Cultivation details

Landscape Uses:Arbor, Seashore, Woodland garden. Succeeds on a warm wall in a good loamy soil[1] in full sun[166] or light shade[200]. Plants can become rampant when growing in rich soils[200]. A very ornamental plant[1], it is hardy to about -20°c according to some reports[184, 200] whilst another says that it is not hardy in all parts of the country but it succeeds in more open positions such as a pergola or an old tree in the southern part of England[1]. Plants require the extra warmth of a sunny wall to induce better flowering[184]. Plants are self-clinging by aerial roots like ivy but are best if given some support[1, 166]. Any pruning is best done in the spring[188]. The seed only ripens outdoors in Britain in hot summers[11]. There are some named forms selected for their ornamental value[202]. Hybridizes freely with other members of this genus[200]. Special Features: Attracts birds, North American native, Invasive, All or parts of this plant are poisonous, Attracts butterflies, Attractive flowers or blooms.

Plant Propagation

Seed - sow spring in a greenhouse at 10°c. Two months stratification at 5°c assists germination[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of almost ripe wood, 7 - 10cm long, July/August in a frame. Slow to root but a fair percentage[78, 200]. Root cuttings 5cm long in December. Fair to good percentage[78]. Suckers, removed in the dormant season.

I have a campsis radicans flava. It has grown every summer for the past 3 years but has never bloomed. Any suggestions?

judithwainwright   Sat Aug 30 2008

Me too, apparantly they need strong fertiliser like tomorite.

Monique Serres   Wed Mar 26 2008

Can Campsis Radicans be planted in a big pot on a sunny balcony and will it survive the winter for next year?
