This is a truly invasive species, Tropaeolum ciliatum has romped over and swamped surrounding herbaceous plantings in the border to the north of the Terrace café with its scandent form of growth. Again, from a deciduous rootstock that gives rise to rapid and prolific growth. Native to Chile where it grows on steep, dry mountain slopes it has become very successful at RBGE. Flowering through the summer into autumn. In sunshine these plants are floristically prolific although the flowers are often lost in the depths of luxuriant foliage. Typical Tropaeolum flowers with a spur peg facing back parallel with the stalk. This is a modified tepal that forms a nectar tube. The petals are a rust yellow with red netting striation markings within.
We have finally found out that this is what is taking over our garden! It appeared about two years back and ever since we have tried with fail to remove it! It strangles out the growth of anything and everything near! We never planted it so can only assume it’s come from a bird or squirrel or something! But it’s becoming a nightmare to control! Have seen it’s very hard to get rid of once there so not sure how to go about getting it out once and for all!
