Plant Features

Cascadias™ Indian Summer Petunia Plants offer lightly ruffled, velvety blossoms that are a mixed bag of Indian summer colors, ranging from yellow to orange to pink, and even terra cotta. Cascadias are heat and weather tolerant petunias the produce compact, bushy plants that creates a blanket of 2-inch flowers that trail nicely out of containers and hanging baskets, or they make a colorful groundcover! Petunia flowers produce a sugary nectar that hummingbirds and butterflies love.

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

Cascadias™ Indian Summer 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. Deadhead weekly. PRO TIP: Remove both the spent flower and its stem, snipping it back to where it connects with the main stem. Otherwise, the seed head will develop, and the plant will think it should slow down its flower production. 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.

What a Beauty

Ahhh...what a beauty! I love this color with it's soft golden yellow with pink hues. It has been blooming profusely since its arrival & transplant less than a week ago thanks to Grow Joy's excellent quality & superior packaging.

Growjoy Petunia’s are far better than any I have purchased from Home Improvement stores. Local nurseries simple don’t have the variety as well!

Lots of blooms

These plants already have a lot of blooms on them, and the peachy color is so pretty in my garden. I recommend this flower.

Love these

I had these last last year and just love them. They are such a beautiful color. I have earth tones in my garden and they fit in perfectly. As always, they arrived in great health.

Indian Summer

I bought one of theses last summer, and one plant covered a small window box . The colors are beautiful shades of a summer sunrise. You won’t be disappointed!

Better than ever

I can't review each individually (too many). All plants in this order (placed last winter) arrived in great condition and packaged extremely well. We have had a lousy spring - looking out at snow from another storm. Won't pot them all until we get a little warmer. Excellent transaction start to finish!

Indian Summer Petunias

This is my 4th or 5th year ordering from GrowJoy and they have exceeded my expectations once again. Even with the harsh past winter my plants arrived healthy and carefully packaged. I wish all online nurseries were this exceptional!

Garden Mom on Petunias
