Calceolaria uniflora (syn. Calceolaria darwinii, known as Darwin's slipper) is a perennial plant of the genus Calceolaria, known as the slipperworts. It is originally from Tierra del Fuego in the southern part of South America. Calceolaria uniflora is a mountain plant growing only to 10 cm (4 in) tall. The flowers are a compound of yellow, white and brownish red.
It's all about getting the balance right when it comes to watering your Calceolaria. Overwatering can play havoc with the plant's roots, but it'll suffer from serious wilting and petal drop if it's left to get too dry. Generously water the plant when the top layer of potting mix is dry to the touch. Make sure you water directly into the medium.
To maximize the length of the bloom period with Calceolaria, feeding with a weak solution of a balanced fertilizer once a week could be beneficial. With a short-lived species like this, it isn't a necessity, though.
