Calibrachoa and MILLION BELLS ®: Advice on planting and maintenance

Very close cousins ​​of Petunias, Calibrachoa has become in the space of a few years an essential plant for the summer flowering of flower beds, pots and flower boxes. Mainly popularized by the MILLION BELLS ® series, Calibrachoa is very easy to grow and decorates gardens, balconies and terraces from May until frost.

Calibrachoas are the result of multiple crosses between species of Calibrachoa and Petunia from South America. The MILLION BELLS ® series was selected at the end of the 1990s by the Japanese firm Suntory. Latin name Calibrachoa honors the Spaniard Antonio de Cal y Bracho (1764-1833) who was an apothecary, entomologist and botanist in Mexico.

Calibrachoas and MILLION BELLS ® form small, dense, branched bushes with a slightly drooping spread. Their small green foliage is adorned with frosted May by numerous trumpet flowers in shades of white, pink, red, blue-violet, yellow, orange, sometimes two-colored or veined, often with a contrasting yellow heart. Despite their hardiness, calibrachoas are freezing in our latitudes and die off at temperatures below -2 ° C / -3 ° C.

Undemanding, Calibrachoas and MILLION BELLS ® are content with good garden soil drained in both sun and partial shade. Even though they are more resistant to heat and more tolerant of transient droughts, Calibrachoas and MILLION BELLS ® appreciate regular watering without excess which maintains the continuity of flowering and more vigorous vegetation.
