I love these little plants (at least mine are little). I always buy up the ones on the "leftover" table at the nurseries in August. They bloom first just before Easter, here. Mine are in hot clay soil, partial shade, and not much moisture; they don't thrive, but they do survive. A neighbor has them in mostly shade and they get HUGE (12" wide by "8 tall); she probably waters and feeds them regularly.

My plant looks just like this one in the foliage and size and height of the blooms. But mine has blossoms formed with two light pink lobes on top and three deep pink lobes below, and it is still blooming in December. There are only two flowers per stem usually. The plant is about 17 inches across and the blooms are about 2 1/2" long and wide. If anyone knows the correct name for mine, please let me know.
I am in North Bay Area of California inland between bay and ocean. I have it in a pot. It didn't like the cold and so it is indoors now (Dec). Last winter it survived (barely)outside and now has bloomed nearly the whole year (from spring until now). It got mealy bugs in the summer from? No other plants in my garden have them! I feed it African Violet food regularly. It is a lovely and durable plant. My mother had it in Southern California before she died and she called it "African Primrose."
Has mid green, broadly lance shaped, toothed leaves with conspicuous veins. Bears 5 petalled, salverform, scented, pale yellow flowers.
Flowers mainly in February - May
Loves a constantly moist but drained soil in light shade. It will tolerate some alkalinity and sun where happy. Easy to grow, it even enjoys clay!
One of the first plants to flower in the year and has been used in the past as a medicinal herb. Among the things it was said to cure are; madness, scrofula and headaches. Today you can buy herbal Primrose tea (please, get advice first from a trained herbalist!) which is suppose to ease; migraines, arthritis, rheumatism, insomnia and as a blood cleanser. A root decotion is sometimes used to treat coughs and other mild respiratory problems.
A strange custom in Germany is; the Primrose is supposed to grow where there is hidden treasure and that it has some power to open locks (if anyone has more details on this I'd love to hear it please)
One from England is that a 6 petalled flower is lucky for marriage and love so keep it!
