Sky-blue Morning Glory (Ipomoea tricolor)

Morning Glory was cultivated in the Japanese empire and bred for a light blue color; that's where the name for this light-blue type of morning glory originates, even when the species is different. Mexican morning glories are annuals and are loved for their exceptionally beautiful, ethereal blooms. They thrive on sheltered house walls, but are still sensitive and fade quickly. There are several cultivars in other colours. Mexican morning glories grow up to approx. 4 m, thus somewhat higher than the common morning glory.

(Mexican Morning Glory or Imperial Morning Glory "Trichter- lat.: Ipomoea tricolor, Ipomoea violacea, pharbitis rubrocaerulea)

Morning Glory "Heavenly Blue"

Requirements / Price

A warm and sunny, wind-protected location is necessary for this rather fragile morning glory. Any normal garden soil will do, strong fertiliser with low nitrogen promotes flower growth. This plant can easily be grown in a pot or bucket. It is available as seeds or as potted plants in spring. Do not sow the seeds as usual in March, but at the end of April / beginning of May!

Characteristics and Pruning

The Mexican morning glory is an annual twining vine that can grow up to 4 meters high. The one-day flowers open before dawn and then fade by the end of the day, especially in the sun... sometimes even by lunchtime... thus its name "morning glory." This morning glory flowers pink and sky-blue with a white center-- with the Latin name "tricolor" because of this tricolority. Some red varieties exist, like the "Scarlett O`Hara" (Ipomoea nil - USA 1939) and "Turris." "Pearly Gates" is a white variety. Flowering time is from July to October, but in cold, wet summers there might be no flowering at all. Seeds are poisonous!
