These Superbells are just okay. This is my first time growing Superbells and I'm really not a fan. I thought I'd like them the way I enjoy petunias, but that's not the case. These are not sprawling. The blooms falter much sooner than I thought and dry out to this mid-deep purple colour, so they definitely need to be dead-headed. We've had cool, wet, weather and heatwave like weather - there's no type of weather that seems to make these plants happy. I've lightened up on watering, to no avail. I have yet to see this peachy-pink color that's seen in the PW double magic grapefruit photos. These flowers are either all yellow or all pink. I just can't figure these plants out and - given that they are Superbells - I thought they'd be productive like the Supertunias and Superbenas. I'm just very, very underwhelmed by these flowers and I don't think a Proven Winners flower (with its higher price tag) should be this much work to try to 'figure out'.

Everything you’ve loved about Superbells Magic® Pink Lemonade, but in double form. This dynamic, color-shifting calibrachoa opens lemon yellow, then takes on soft pink tones as it basks in the summer sun. The overall effect is like two pastel calibrachoas comingling in one captivating combination. It’s stunning in hanging baskets, window boxes and upright containers where it mixes beautifully with other flowers. Try pairing it with Superbena® verbena or Goldilocks Rocks® bidens. Like all Superbells® calibrachoa, Superbells Magic® Double Grapefruit blooms from spring into fall without deadheading.

They will do well in the ground only with good drainage. For most gardeners containers are the best use for Calibrachoa.
Maintenance Notes:Superbells® calibrachoa plants are easy to grow and will flower non-stop from planting to hard frost if simple maintenance tasks are performed. Growing Superbells 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.
Calibrachoa’s roots are sensitive to wet soil and extreme soil pH levels. For these reasons, they grow best in containers with a well-drained potting mix such as Proven Winners Premium Potting Soil. If your garden soil is well-drained and slightly acidic, you may be able to grow calibrachoa in the ground.
Superbells calibrachoa thrive with average moisture and prefer the soil to dry out a little bit before they are watered again. They do not grow well and may develop root rot in soggy soil. However, do not let the plants wilt severely before watering again.
Superbells 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, Superbells should be fed with Proven Winners Premium Water Soluble Plant Food every third time you water or at least once per week according to the rates specified on the packaging.
By midsummer, it will be time to trim up your Superbells. Trim the longest stems, bringing them in line with the others, taking care not to remove more than 20% of the plant. Follow up by feeding them with water soluble plant food to promote fresh new growth and blooms.

I had my favorite Garden Center order the Double Grapefruit for me. I picked six of them up in early May (Zone7B) and planted just them together in a pot. They get about 6 hours of full sun a day. The first flowers however bloomed a bright pink color only, not yellow and nothing like the tag. I even called the owner and asked if she was sure I had the right plants. She said yes but offered to take them back if I wasn’t happy. I kept them and waited. My weather was fairly cool still especially at night. As the weather warmed up into late May the bright pink flowers transitioned to a softer pink and then to just like the pictures- a mixture of soft pink and yellow. I was very happy. But now near mid June the weather is in the 90s. And all the flowers on the plants are now yellow only- no pink at all. This is not at all what I was expecting. I’ve been taking pictures of their color changes to see if I can find a pattern. The plants themselves are growing very well and are constantly blooming. Just not what I expected.
