(Petunia) Supertunia® Royal Velvet® Petunia has striking rich velvety purple flowers that are virtually maintenance free and bloom continuously throughout the season.  The medium to large sized blooms of Supertunia® Royal Velvet® have thicker petals which provide good weather tolerance and are not only attractive to us, but will bring in the butterflies and hummingbirds.  Supertunia® Royal Velvet® Petunia grows 6-12” high and can trail up to 48” making it a great choice for your hanging baskets, window boxes, combination planters and even in the front of the landscape border.  The Supertunia® family of petunias are self-cleaning. What that means is that you do not need to deadhead them to keep them looking beautiful and full of blooms all summer. We do recommend fertilizing your Supertunia® every 1-2 weeks with a water soluble fertilizer. This helps keep your plants well nourished providing you with loads of color. You may find that mid season your baskets and planters need a manicure. We recommend trimming your Royal Velvet® back to approximately the bottom of your hanging basket or container. This will encourage more branching and freshen up your planter.
