Plant Name: Agapanthus sp.

Description: long, strap-like fleshy leaves feature strong flower heads in various colours over summer.

Size: foliage to 50cm – flowers above. Dwarf varieties available.

Special comments: look at some of the new varieties being released that feature dark colours, such as ‘Black Pantha’ and ‘Back in Black’. An advantage of these new cultivars is that they are generally sterile and so won’t seed into bush areas causing weed problems.
