Reticulata Iris
 |
 |
Reticulata iris are the bulbous iris that bloom in February, and are the harbingers of spring, the name being derived from the loose “net like” skin that covers the bulbs. Most species have a quadrangular cross-section to their leaves, and flower up to 15 cm (6”).
The ten species grow best in a well draining bulb frame, or in deep “long tom” pots in a cool greenhouse, using John Innes no.3 compost with added grit. The species I reticulata, histrioides and winogradowii, and all hybrids will grow outside in a sunny, well draining spot, rock garden or border, with I winogradowii requiring a richer humus soil, and more moisture when dormant. The bright yellow I danfordii needs deep planting to stop the bulbs breaking up to “rice” bulblets.
