This rosemary cultivar, "Irene " is considered a trailing type, good for hanging baskets, in footed urns, or hanging over edges of walls or drooping over things, etc.

But beware : all rosemaries are thirsty little boogers, so if it is in a hanging basket or in a pot, moisure needs to be monitored and adeqquiately watered or the plant will quickly dry out nd not recover.

They are happiest in the ground.

They originated in a mediterranean climiate and do best in similar
conditions.
