Tropical plants usually have flowers with warm colors like red, orange, or yellow. Only a few produce blossoms in the shade of amazing peacefull blue.
Here are five tropical vines with stunning blue flowers that could transform your garden into a chill-out zen sanctuary. An added bonus is that they are all super easy to grow.
Thunbergia (Thunbergia grandiflora)
Thunbergia (also known as Bengal clock vine, blue sky vine, and blue trumpet vine) is a fast grower—it can grow up to a foot (30 cm) a day! Native to Southern Asia’s tropical regions, Thunbergia blooms prolifically, producing large royal blue flowers in pendulous clusters. This vine can grow in any soil type but requires full sun for flowering.
Blue Butterfly Pea (Clitoria ternatea)
Originated from Southeast Asia, this plant belongs to the legume Fabaceae family. Its butterfly-shaped flowers have bright indigo blue petals with a creamy white center. The pretty flowers bloom in the morning and last only one day. After flowering, small peas develop and mature into edible pods about 2-3 inches long.
Blue Jade Vine (Strongylodon macrobotrys)
Also called jade vine or emerald vine, this remarkable plant is native to the Philippines’ lush tropical rainforests. Best known for its showy, cascading claw-shaped flowers in luminous turquoise or blue-green color. Each flower cluster can get as much as 3-4 feet (1.5 meters) long and contain 70-80 buds and blossoms. Like blue butterfly pea, blue jade vine belongs to the Fabaceae family.
Plumbago (Plumbago auriculata)
Plumbago is not a vine but a hardy herbaceous plant that grows like a vine. It can climb onto anything it can reach, producing a cluster of pretty sky-blue, tubular blooms.
Queen’s Wreath (Petrea volubilis)
Queen’s Wreath well known as Sandpaper vine flower. Purple Wreath is a very lovely small climber with drooping long racemes of delicate violet-purple star-like flowers. It is a semi-shrub and semi-climber and the small wooden trunk develops artistic curves over the years. It looks as if an Ikebana expert has shaped it for his floral arrangement. It grows best in sunshine. It flowers in spring and in some areas also in November.
Morning Glory (Ipomoea sp.)
Morning glory belongs to the Convolvulaceae family and is closely related to sweet potatoes. Native to tropical regions of South America, this fast-growing vine is a must-have for many gardeners, beloved for its heart-shaped leaves and cheery, vibrant flowers. Morning glory ‘heavenly blue’ is everyone’s old favorite; however, new cultivars produce fascinating bicolor or tricolor blooms in all shades of blue!
