Botanical Name

EVOLVULUS 'Blue Daze'

Plant Common Name

Blue Daze Dwarf Morning Glory, Dwarf Morning Glory

General Description

For a member of the morning glory family, ‘Blue Daze’ is unusual because it does not twist or climb and is a hybrid derived from plants native to North and South America. The trailing stems of this tender perennial subshrub form a low, lax, spreading mound. Both the stems and the small, oval shaped leaves are densely covered with short, downy hairs, giving them a silvery appearance. Many small, sky blue, funnel shaped flowers with five lobes and white throats cover the plants throughout the warm growing season. Each flower lasts only a day, but is quickly replaced with new ones the next day. Typically grown as an annual, this widely available cultivar provides an easy, reliable source of summer color.

'Blue Daze' thrives in hot weather and sharply-drained soil of modest fertility, but will also perform quite nicely in average, well-drained soil or potting mix. Full sun is preferred, but the plants are tolerant of a bit of shade. Water frequently, but avoid standing water or soggy conditions as these could cause fatal fungus problems.

Perfect for hanging baskets and containers, the pale, gray-green leaves and cheerful flowers of 'Blue Daze' also look lovely at the front of mixed beds and borders. Where hardy, it may be used as a small-scale groundcover or accent plant in the tropical mixed border or foundation bed. This plant tolerates salt and grows well in gardens or containers in coastal areas.
