Supertunia Tiara® Blue Petunia (Petunia hybrid 'INPETTIABL') offers striking deep violet-blue petals paired with a soft white center, creating a mesmerizing effect in any sunny garden or container. The stems trail up to 36 inches and deliver a lush, draping display of color from spring through frost. The slightly mounded form serves as an ideal filler or spiller in mixed planters, while the bold flower hue draws attention. Its nonstop blooms and easy upkeep make it a go-to choice for seasoned gardeners and beginners alike.
Supertunia Tiara® Blue thrives in hot, dry conditions with minimal fuss, thanks to its drought tolerance and self-cleaning blooms. Butterflies, bees, and hummingbirds often stop by, adding motion and life to your space. Plant it near the front of landscape beds for a neat yet impactful border, or allow the trailing stems to cascade from hanging baskets and window boxes. Developed via cutting-edge breeding, Supertunia Tiara® Blue Petunia reliably delivers a splash of dynamic color all season long.
Supertunia Tiara® Blue Petunia Care
Provide moderately fertile, well-draining soil and six or more hours of direct sun each day. A light, consistent watering schedule helps maintain steady blooms without over-saturating the roots. Mix a controlled-release fertilizer into the soil at planting time; then follow up with regular feeding (weekly or bi-weekly) using a water-soluble formula for maximum performance.
Use sharp shears if the plant appears leggy, and remove any weak or broken stems to promote a healthier shape. Trimming spent stems by about 20% once or twice a season can encourage new branching and fresh growth. If an allover trim is performed, pair it with a dose of liquid plant food to jumpstart rejuvenation. In containers, keep an eye on moisture levels during peak summer heat; a thorough soak whenever the top inch of soil dries works best. Winter care is typically unnecessary for this annual in cooler regions, though some gardeners in zones 10 and 11 may overwinter it by transferring pots to a protected spot.
Supertunia Tiara® Blue Petunia Spacing
Position individual plants 12 to 24 inches apart for effective ground coverage or tight groupings in flowerbeds. When using containers, opt for a pot about 12 inches wide or more to offer ample room for root growth and trailing foliage.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
