Galaxy Petunia Guide [Care Tips, Pictures, and More]

Deep purple petals speckled with contrasting brilliant white spots are the crowning glory of Galaxy Petunias. Just like snowflakes, no two petal patterns are alike. Interestingly, the amount of white speckles depends on the daytime and nighttime temperatures. Too much coolness will make the petals turn white while too much warmth will turn the petals almost completely purple. Warm days and cool nights create the perfect recipe for a balance of the two colors.

Long lasting blooms decorate the bright green foliage on this annual plant. Its semi-trailing habit is also mounded in growth, making it a very dense herbaceous annual.

What is Galaxy Petunia?

Since the 1800's, Petunia varieties have come a long way in their attributes and diversity. They began as an ordinary, leggy plant with not much going for it. Over the past two centuries, gardeners and scientists have bred these plants and have created amazing, interesting cultivars.
Selecta One, a global horticulture company, first created the Galaxy, or Night Sky, Petunia in 2015. The company is committed to sustainably breeding and creating new high quality plant varieties. Both products and marketing are essential to the brand, so the Night Sky Petunia was a breakthrough petunia variety.
Since the inception of the very first Galaxy Petunia, Selecta One has introduced more unique color varieties into their "Sky" collection. White speckles adorn petals that can be lavender, magenta, or royal purple. The speckles vary in size, reminiscent of the sparkling stars in our night sky.
Galaxy Petunia's latin name is Petunia cultivars.
