    Features

    Supertunia petunias are vigorous with slightly mounded habits that function as both fillers and spillers in containers. These striking blue flowering annual plants are also excellent landscape plants, best suited to be placed near the front of beds. Blue Tiara petunia performs beautifully as a trailing petunia plant, producing medium to large-size flowers all season.

    Maintenance Notes: 

    Supertunia® petunia plants are easy to grow and will flower non-stop from planting to hard frost if simple maintenance tasks are performed. Growing Supertunias in full sun to part sun is important for their strong growth and bloom performance. They do not require deadheading, meaning the removal of spent flowers, to stay in bloom all season.

    Petunias thrive with consistent moisture. Do not let them wilt severely before watering again.

    Supertunia petunias perform best when fed regularly with Proven Winners plant foods. At planting time, in containers and landscapes, mix Proven Winners Premium Continuous Release Plant Food into the soil, following the rates specified on the packaging. Reapply halfway through the growing season.

    Additionally, Supertunias should be fed regularly with Proven Winners Premium Water Soluble Plant Food according to the rates specified on the packaging. For Supertunias growing in containers, feed every third time you water or at least once per week. For Supertunias growing in the ground, feed once every one to two weeks.

    If you have been feeding your petunias regularly and they are getting enough sun and water but are not blooming, you may be dealing with petunia budworm. Learn more about this petunia pest.

    By midsummer, it will be time to trim up your Supertunias. Trim the longest stems, bringing them in line with the others, taking care not to remove more than 20% of the plant. Trimming petunias in the landscape is not usually necessary but cutting them back by 20% can make the plants fuller. Follow up by feeding them with water soluble plant food to promote fresh new growth and blooms.

    • I purchased several Tiara blue peturnias at Home Depot in Palm Springs and Rancho Mirage CA, in addition to a few jazzberry, black cherry and indigo. Its been a week and most of them didnt survive, especially the Tiara Blue and indigo. (Ive had more survive of the others, but not all, whereas all of the Suncal and wave petunias I planted survived.. I'm an experienced gardener. Initially, I thought either the fertilizer I used burned them (Biotone) or they were overwatered. I tried again and purchased several more. Upon arriving home, they were dry and I watered them. The following day when I checked the pots, the bottoms were sitting in water, even though the pots have holes. I wrung out the excess water and planted them, this time using only water soluable fertilizer and using new Miracle Gro potting sol. Again, most of them are dying, even though other petunias and geraniums in the same pots are doing well. I'm not sure if Proven Winners uses a different soil mixture to retain water since these were purchased in desert locations, and that is causing the issue, or if this strain of peturnias has issues. I spent a lot of money on these and am very disappointed.

    • Wow! This plant provided so much consistent, vibrant color in my flower bed this summer! Incredible plant that spread, but didn't take over. I plan to buy more for next Summer!

    • The Tiara blue petunia is beautiful - some plants are blossoming well while others within the same grouping are struggling. I’m experiencing only one or two tiny flowers with little plant growth! I used PW sprinkle fertilizer and followed up with PW soluble fertilizer! I refresh this flowerbed for new blossoms every year - I have to assume it’s an issue with this specific new strain! Your advice is appreciated!
