PLACEMENT & CULTIVATION
Cultivated since the late 17th century, dwarf morning glory 'Royal Ensign' has starry rings of white and yellow etched on a deep cobalt blue trumpet-shaped flower. Great spilling over containers or allowed to weave among summer annuals where they add a pop of color. These continuously blooming flowers are effective garden edgers too. Easy to grow, they require little care, just lean soil and sun. Afternoon shade is best in hot summer areas.
While somewhat drought tolerant, Convolvulus does best with about 1" of water per week, especially during dry spells. Do not over water.
Slightly acidic to slightly alkaline
If soil is especially poor, mix in a few inches of compost prior to planting.
Diseases & Pests:
No major problems. If aphids appear, hose plants down daily until the problem is resolved. Insecticidal soap is another option, especially if spider mites are found.
