You're the ARTIST, I'm the PAINT.

Supertunia petunias are vigorous with slightly mounded habits that function as both fillers and spillers in containers.  They are also excellent landscape plants, best suited to be placed near the front of beds.  They have medium to large sized flowers.  The flowers are violet-purple with a wide green edge.

Maintenance Notes: 

Self-cleaning, no deadheading necessary, this is not necessarily true of all Petunias.

Fertilize often for best summer performance.

Late July and August is when plants should be at their best, but there is only one problem: The plants have run out of energy and the gardeners realize it too late to help the plants recover. This is especially true in raised containers and hanging baskets. Here is the best way to keep your Petunias in the Super category.

1. When you buy them in the spring, buy a slow release fertilizer to top dress the basket or container. If you plant your own basket, incorporate some of the slow release fertilizer in the soil as you plant. Follow the package directions.

2. In May fertilize with a water-soluble fertilizer once every two weeks. Mix up the fertilizer and water the plants just like you would if you were using clear water. It normally takes a good half of gallon of water to really water a 10" wide basket or raised container.

3. In June as the weather starts to get warm to hot, fertilize weekly, again with a good soaking. If the weather turns really hot as it sometimes does in Late June you may need to fertilize every third watering. By now the Supertunia is really growing and starting to tumble down from the basket or fill out across the flowerbed.

4. July is when the cutting back occurs. Around the 4th of July, (after your big party) get some of the slow release fertilizer that you bought in spring and re-apply across the top of the planter. At the same time, trim back some of the longer branches just enough to bring the plant back in line with the bottom of the pot or basket. Don't remove too much at the maximum cut back 20% of the branches or 1 in five shoots. You can also just give it a general light trim. Your plant will be out of flower for a few days, but will come back stronger than ever. By now with July's heat you should be watering at least every other day and begin to fertilize every other watering. I know it sounds like a lot, but if you want a plant to grow like an elephant and be the most it can be, you got to feed it like an elephant!

5. August is, hot, humid, & sometimes with monsoons. Keep up the water and fertilizing, and again, if the plant starts to look straggly remove a few more branches but never more than 20% or give it a general trim as before.

6. It is September and the plants should still look good, start to back off the watering and the feed, but shape the basket with the last pruning of the season.

I know it sounds like a lot of work, but it really is a labor of love. I fertilize my baskets and my garden every time I water, and I water daily from mid July through August. I recently invested in the WaterWise irrigation system and let me tell you it really works. You will find that your Supertunias, along with all the rest of your plants will keep looking fantastic through September and perhaps with the luck of a gardener and a late frost maybe even into October.

The Best Petunia. Period.® The unique bicolor of this Petunia has created a tremendous amount of interest from gardeners, with its deep violet throat and softer violet petal surrounded by a chartreuse edge.

Picasso Supertunias Standing out from the crowd with their artistically painted blooms is what Picasso Supertunias do best. Their novel flowers have tremendous impulse appeal and their performance matches the high standards set for all Supertunia® varieties.

  • I Love this Petunia Pretty much Picasso. I Bought the last 2 starter plants Fred Meyers had. I Planted them in a antique Wheel Barrow. They just bloom and bloom and are even brighter than the picture you show. I want to plant them every year.

  • When I planted the 4" plant in a 14" container, I considered planting more than one, but am glad now that I didn't. The one plant completely fills the planter and cascades over the sides to the ground. It blooms non-stop.

    Above Average Superior performance, among my favorites, would recommend to others.

  • beautifully growing plant...but absolutely the STINKIEST petunia I have ever grown.
    Actually had to move containers and hang them off the shed ( 80 feet from the house).
    When plant gets wet thru watering or rain...they REEK!
    So pretty, but UGH, never again, even the neighbours complained of the smell.
    Finally mid-summer had to pull, bag and trash them. Hubby wouldn't stand for the smell around his shed!

    Unsatisfied Did not survive, inferior performance or did not bloom well - won't grow again.

  • This is a beautiful,dense and extremely prolific plant! Coupled with deep purple Angelonia and ornimental sweet potatoe vines my deck looks beautiful.

    However, it has a nasty and foul odor when wet. Typically, I water in the morning, but on a humid day, or after a rain, it is impossible to enjoy the fresh air due to this plant. Is there a comparable plant that is as densely flowering and is less offensive smelling?
