No summer garden is complete without Agapanthus. The blue varieties are perfect with dark red Dahlias,
brown Heleniums, yellow or red Hemerocallis, and all manner of Kniphofias. I plant white varieties with silver Artemisias.
Agapanthus in containers are also a must for summer. Plant them in tubs or large pots.
Their bold architectural heads of flowers make a perfect backdrop for Pelargoniums.
After flowering Agapanthus seedheads, first bright green, later turning brown, continue to provide invaluable bold graphic shapes into the late autumn.
