Dietes grandiflora flower

The large flower of Dietes grandiflora is characterised by prominent dark yellow nectar guides positioned on the lower halves of the three bigger (outer) tepals. The smaller (inner) three spoon-shaped tepals are white. They are embellished with thin, sometimes parallel brown line markings at the base. The grandiflora specific name is derived from the Latin words grandis meaning great and flora meaning flowers, referring to the flower size, which is about 10 cm in diameter.  

The pale blue to violet style is conspicuously branched into three flattened petal-like sections ascending over the outer tepals, and hiding the anthers.

These plants flower abundantly at the tips of erect stems about 1 m tall. Bloomtime is from spring to early summer. The plants often flower after rain. The flowers last for only two or three days, rendering them just about unsuitable as cut flowers.

The large, oblong, green fruit capsules are borne erectly. They split open widely when ripe, releasing small dark seeds (Manning, 2009; Pooley, 1998; iNaturalist).
