This extract from AG 6 January 1968 looks at flowers with three petals
Golden triangles
Add more interest to your garden, says Nancy-Mary Goodall, with ‘triangular’ flowers
A SOLEMN little boy once told me that it was unnecessary to try to remember flower names since all flowers can be divided into roses, daisies and hollyhocks, a system that served him well. It is true that most flowers are round, spiky or starry, but he had not noticed another shape of flower – the triangle. Triangular flowers look so different from those to which we are accustomed that they always arouse interest among visitors to a garden.
The most striking is , so-called from the Latin names for a tiger and a peacock, and one would think it difficult to live up to such a dramatic name. The tigridias more than deserve it. They are almost perfect triangles 3in (8cm) across and brilliantly coloured. There are forms in red, yellow, orange, pink, white and lilac, and they are spotted and striped in maroon over the concave centres.
