This year agapanthus started flowering early and it is going to seed early. It is an invasive weed which can take over bushland. It is very common in gardens and the borders of natural areas in Blackheath and spreads readily from seed.
To reduce its spread use secateurs to cut off the flower heads at the base of the stem and dispose of all dead flowers and seeds in your green bin. Small plants can easily be dug out and disposed of in the green bin.
BMCC green bin and composting processes ensure the plant material does not spread. Placing plant material in a red bin means it goes to landfill.
