When I lived in California, Agapanthus was a landscape stable with its evergreen 1-inch strap-like leaves and globe-like cymes
of blue (white or pink) flowers atop 3-4 foot stems in the summer. These plants could take heat, drought and even survive being
burned as one
neighbor discovered. What they couldn't withstand was cold weather and often died in temperatures below about 25 degrees.
I tried unsuccessfully for years to grow Agapanthus here, even digging and storing the tubers over the winter.
Along comes the cultivar Midknight Blue® (yes, that's the correct spelling) which is advertised as being able to withstand
temperatures to -10 degrees. So, I'm planting a fresh crop of these directly into the garden to see how well
they'll perform. In zones 8 and warmer, these plants were definitely evergreen. However, I do not know if they
will remain evergreen in zones 6 and 7. In any case, those deep dark blue flowers are worth the effort.
Plant MB Agapanthus in full sun in average to rich garden soil. Good drainage is key. The roots (tubers) will rot if
they are grown in poorly draining, compacted soil or clay. These plants will perform extremely well in the sandy soils
of southern Georgia and Florida.
Grow MB Agapanthus in a mixed shrub/perennial bed, cottage, rock or cutting garden. Although the foliage remains at about 2 feet, the flower stalks can
shoot up to 3-4 feet tall, so plan(t) accordingly. Good companion plants include ornamental herbs (Agapanthus is NOT edible), roses,
hardy succulents and cacti, conifers (especially those with golden foliage) and other full sun, drought tolerant plants. They
also grow well in containers.
Although I have seen this plant for sale at these nurseries, I cannot guarantee that they will have it in stock
at the time of this publication.
