Plant Features

Supertunia® Royal Velvet® Petunia Plants offer exceedingly rich, purple-blue blossoms that refuse to fade, even as the blossom itself begins to fade. The diminutive throats are almost black in color. The heaviest veins and midribs are colored the same lush, steadfast purple as the throat, providing a 5-rayed star and contrasting decoration on each individual petal. This heat and drought tolerant plant blooms all season! Self-cleaning, no deadheading necessary. Petunia flowers produce a sugary nectar that hummingbirds and butterflies love.

Supertunia Petunia Companion Plants: Gaura, Salvia, Lobelia, Snapdragon, Coleus

Supertunia® Royal Velvet® Petunia Plant Care Instructions: For optimal performance, keep your plants well-watered. Choose containers with functioning drain holes as petunias will not tolerate wet feet. Trimming will help keep your petunias looking fresh all season long.

Here are our favorite methods:

  1. Trim a third of the plant back by a third, this should be done every other week, cycling through the three areas.
  2. Find the longest stems that only have one flower and trim them to the main stem, this method should be done weekly.
  3. The most drastic approach would be to trim back the complete plant by 1/3 every 6 weeks.

The plants arrived in great condition, planted immediately and they’re doing great!

Beautiful and easy

I use petunias for my planter on my deck. They are beautiful and drought resistant. Also last until early November in the Illinois weather. I tried them out last year and liked them so much I ordered them again. I also purchased other colors. Buying them again for the years to come.

The plants arrived large and healthy and are now blooming profusely in their containers.

I'm a fan!

I LOVE supertunias! I bought another type of petunia, and it just can't compare. No matter where I plant them, they thrive. This particular beauty has such a deep, rich color that doesn't fade. The lime green foliage is also a great contrast.

Very, very pleased

This year, bc of social distancing, I ordered plants from about 10 different sites. I had never ordered from GrowJoy before, but will DEFINITELY use them again! The plants were beautiful. Not a spot of damage and the soil was still moist. They barely knew they were transplanted and immediately started growing vigorously. The difference in the plants from different places was unbelievable. This was an eye-opening experience.

Supertunia Royal Velvet Petunia

I ordered two of the Royal Velvet Supertunia and am very pleased! Both arrived intact and very healthy. One plant has already had a gorgeous bloom and I know there will be many more as it matures and spreads. They were planted in hanging fence planters next to the Bordeaux purple Supertunia. GrowJoy is the perfect resource for ordering specific plants (in this case the Supertunia) and specific colors. Thank you, GrowJoy!
