Rook leg (Geranium purpureum)

When we talk about geraniums, it is very easy to think of plants with a perfect size both to grow in pots and in the garden. The species I am going to tell you about next is not far behind: its name is Geranium purpureum.

What is special about this plant? Well, the flowers are the smallest of the genus, but they are very pretty. In addition, taking care of it is so simple that it will be difficult for you to believe that it is like that . Get to know it.

Origin and characteristics

It is an evergreen shrub native to the Canary Islands, whose scientific name is Geranium purpureum, and the popular “rook leg”. It reaches a height of up to 70 centimeters, with widely divided leaves with serrated margins, and purple flowers of up to 2 cm.

It is very similar to Geranium robertianum ; in fact, they are very easily confused. But it differs from this one by the anthers, which are yellow (and not purple), and the petals that measure from 5 to 9.5mm by 1.5 to 2.5mm ( G. robertianum has them larger, 10- 14mm by 3.5-5.5mm).

  • Location: Place it outside, in full sun or partial shade.
  • Land:
    • Pot: 60% black peat + 30% perlite + 10% earthworm humus.
    • Garden: grows in fertile soils, with good drainage.
  • Irrigation: it has to be watered about 3-4 times a week in summer, somewhat less the rest of the year.
  • Subscriber: in spring and summer it is advisable to fertilize it with fertilizers such as guano or compost, once a month or every 15 days. If you have it in a pot, use liquid fertilizers.
  • Multiplication: by seeds in spring.
  • Pruning: not necessary. Remove only withered flowers and dry leaves.
  • Hardiness: it is sensitive to cold, more than other geraniums. Ideally, it should not drop below 0 degrees.
