Passiflora caerulea Cultivation | Propagation | General Uses Cultivation Notes: Requires a well-drained soil with plenty of moisture in the growing season, otherwise it is not fussy[1, 200]. Dislikes highly alkaline soils[202]. Hardy to about -15°c, if plants are cut down to the ground by frost they can regenerate from the base[200]. Very fast growing[11]. Roots of outdoor grown plants should be restricted to encourage fruiting[1]. Plants produce tendrils and climb by attaching these to other plants. The plant has a very long flowering period, from early summer to early autumn, though individual flowers only live for about 48 hours[245]. The flowers are delicately scented[245]. The cultivar 'Constance Elliot' is more fragrant[245]. If fruit is required it is best to hand pollinate using pollen from a flower that has been open for 12 hours to pollinate a newly opened flower before midday[88, 200]. The flowers open in sunny weather and do not open on dull cloudy days[219]. Fruit is only formed after long hot summers in Britain[166]. Plants are very tolerant of pruning and can be cut back to ground level if required to rejuvenate the plant[202]. Any pruning is best carried out in the spring[219]. Plants in this genus are notably resistant to honey fungus[200]. For further Passiflora caerulea gardening information |
