Freesias are a native flower of South Africa
There are 19 species which are found nowhere else in the world. The oldest known species which was cultivated overseas was F. refacta. With the introduction of a pink flowered species F. armstrongii which flowered at Kew in 1898, hybrids between these 2 species were developed to give the modern strains.
The species F. armstrongii resembles F. refracta in shape and size , but the flowers are pink. it was discovered at Humansdorp in the eastern Cape and is one of the parents of the modern hybrids.
The yellow spotted freesia F. flava was formely a variety of F. sparmannii . This variety has fragrant creamy flowers with a deep yellow blotch on the middle petal of the lower lip. The base colour of the flowers varies from pure white to yellow, but they all have the deep blotch. This species comes from the eastern Cape near Albany.
The species F. sparmannii are a fragrant flower and have pure white or creamy, wide -open flowers, sometimes tinged with blue on the outside of the petals. They come from the eastern Cape.
The best known species is F. refracta usually known as the common freesia. They have a stem length which varies in height from 15cm to 50cm and has a branching stem. The flowers each measure about 4cm in length. they are a greenish yellow and suffused with dull purple on the outside of the upper petals. The lower petals are marked with brownish yellow and each has a purple line down the centre. A number of horticultural varieties have been named , but these are believed to be separate species
