Omphalodes cappadocica, Cappadocian navelwort, is a low-growing evergreen perennial native to woodland habitats in Turkey. In spring it carries loose clusters of bright blue flowers with white eyes above a spreading mat of slightly hairy, oval, pointed leaves. The flowers closely resemble forget-me-nots and provide true-blue color in shade gardens where that hue is hard to find.
It grows best in part to full shade in consistently moist, humus-rich soil. Direct sun or dry conditions cause leaf scorch and reduce flowering. A layer of organic mulch helps retain soil moisture and keeps roots cool through summer. Plants spread gradually to roughly 16 inches wide, forming a tidy, non-invasive clump. Dividing congested plants every three to four years maintains vigor.
Powdery mildew
White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.
Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.
Root rot
Plants wilt, yellow, and stunt even in moist soil; lower stems and roots turn brown, soft, and mushy and the plant may collapse. Most common in heavy, wet, or poorly drained ground.
Improve drainage and stop overwatering, and never plant too deep. Lift and destroy badly affected plants along with the soil around the roots. Grow in raised or free-draining beds to prevent it returning.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
