The Queen Mum Agapanthus from the Southern Living Plant Collection produces gorgeous globular clusters of trumpet-shaped white blooms with blue throats. These blooms appear in spring into summer.
The Queen Mum Agapanthus is semi-evergreen, which means that warmer USDA Zones will find it to be evergreen and colder Zones will see it as a deciduous perennial. This foliage is thick, elongated, and straplike, with a leathery sort of texture. Additionally, it’s an attractive bright green hue that goes with just about anything in the landscape or garden.
This is a semi-dwarf variety that reaches about 1-1.5′ H x 1-1.5′ W. It has a natural clumping habit, so it won’t take over your garden. However, as with many perennials, divide your Queen Mum Agapanthus every 3-4 years to prevent crowding.
Use this as a border plant along a walkway, as an accent in a mixed garden bed, in a container, or as a mass planting.
Hardy in USDA Zones 8-10, down to 10°F when established.
Plant in Full Sun to Part Shade for best results.
Water 3-4 times per week during the first growing season. In the second growing season, provide supplementary water in times of extreme heat and drought.
The Queen Mum Agapanthus prefers garden soil with good drainage for best results.
Perennials rarely need supplemental fertilizer, however, 3-4 inches of compost around the plant yearly provides nutrients to keep the plant happy and healthy.
Space individual plants about 12-18″ apart for a seamless planting. Plant over 2 feet apart for space between clumps.
