Blue Diamond™ Petunia hybrida

Red Carpet Blue Diamond™ is a compact Petunia hybrida selected for a distinctive dark blue and white star pattern. The breeder describes a controlled habit, early flowering and good garden performance, with a mature height of 6 to 10 inches and spread of 10 to 14 inches.

Its modest height and broader spread let it fill containers and edge planting areas without the long, cascading growth of a trailing basket type. Danziger lists it for hanging baskets and ground cover. ## Flowers and season Large flowers carry a dark blue ground with a white star-like pattern. The compact plants are suited to early seasonal color, and the controlled shape works well where a tidy container display is desired. ([Danziger product page](https://www.danzigeronline.com/catalog/annuals/blue-diamond/)) ## Maintenance Plant in a sunny location and use a freely draining container mix. Water when the surface begins to dry, keeping the root zone evenly supplied without leaving the pot waterlogged. Remove spent flowers or trim lightly if the plant becomes uneven, and refresh container fertilizer according to the product label.
