Hardy Geraniums

Don't mix those up with the annual bedding geraniums! These hardy geraniums are very easy to grow. There are lots of different varieties available that vary greatly in size, foliage and flower color (pink, purple, blue or white). Some of them are great for groundcover like Geranium macrorrhizum. Choose a suitable variety for your needs.




Limnanthes douglasii - Poached Egg Plant

limnanthes douglasii, poached egg plant flowe


Strictly speaking this plant is an annual but it reseeds freely and forms large areas covered in cream and yellow daisies that look like a poached egg. It flowers in spring to early summer. After the flowers are finished the plants die back but regrow right away from the seeds. They keep the ground covered (in mild areas) during the winter.




African Daisies - Osteospermum ecklonis and jucundum

African Daisies are great seaside plants that will flower from spring till late summer. The purple or white daisies thrive best in full sun to part shade. They can form large mats and cover larger areas. A great plant for the edge of large rock gardens even in exposed gardens. In areas with hard frosts this plant might not survive the winter. Take cuttings to overwinter inside or treat them as an annual.
