Helt generellt så klarar nävor de flesta lägen, bar det är väldränerat.

About the Geranium - Jolly Bee :
The Geranium Jolly Bee, 'Pelargonium', a Proven Winners selection, has rich, deep-blue flowers with white eyes that bloom from June till August. With its beautiful dark green foliage, it has a plant width of 12” and a height of 8-12”. ‘Jolly Bee’ needs to be cut back in early summer for repeat bloom time in the fall. ‘Jolly Bee’ Geranium, being drought tolerant, needs a full sun area with some shade in the afternoon.
For best results, plant in a dry to moist area in a well-drained site. The Geranium family is well known for its stunning fall colors that include reds, oranges, and yellows. It is a superb plant for cottage gardens, container growing, borders or informal borders in mass plantings. There is an attaction to bees and butterflies and it is very disease and deer resistant. A great plant for a beginner gardener.
