From March to May you have early color in your garden and the plant blooms abundantly with yellow flower clusters.
The flowers smell wonderfully sweet and aromatic, especially at dusk and evening. It is a blend of honey nectar with the freshness of lemon and is also liked by bees.
If you touch the center of the flower with a blade of grass, the sensitive flowers and stamens close.
After flowering, green fruits initially appear that slowly turn blue/black. These berries are slightly frosted with a gray haze.
The berries are edible, but the seeds are poisonous! As also the roots of the plant are poisonous and not suitable for consumption.
The berries would be used for fresh juice, jelly compote and jam. However, opinions are divided about the use of the ripe black currants.
The Mahonia aquifolium is a drought tolerant and very strong plant and can survive a drought well.
