Geranium Karmina Plants for Sale Online

Geranium Rozanne produces huge violet-blue flowers with white eyes and reddish-veining. The gorgeous flowers are held above the deep green foliage that has a slight chartreuse marbling. Rozanne is one of the longest blooming plants in the garden. Its flowers are sterile, which keeps the blooms coming from late spring into mid-fall. Having sterile flowers means that there is no chance of this hardy perennial self-seeding.

Geranium Rozanne is a fast-growing hardy perennial so give her plenty of room to grow. In one season, one plant will cover a 2 to 3-foot area. It looks especially nice when complemented by yellow or chartreuse foliage such as Creeping Jenny.

Chosen as the 2008 Perennial Plant of the Year.

How to Care for Geranium Rozanne

We suggest when planting your newly purchased Geranium Karmina plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Geranium Karmina does prefer drier soils in the winter so if there was ever a plant that we would recommend not adding topsoil or compost this is one. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occurring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardener’s best friend and can help guarantee your success.
