Amaryllis
Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs with two species. With proper care, an amaryllis bulb will grow, bloom, and rebloom for decades.
In warm climates, the leaves are produced in the autumn or early spring, depending on the onset of rain, and eventually die by late spring. The bulb is then dormant until late summer. The plant is not frost-tolerant, nor does it do well in tropical environments since it requires a dry resting period between leaf growth and flower spike production.
Iris
Irises are perennial plants that grow from creeping rhizomes (rhizomatous irises) or, in drier climates, from bulbs (bulbous irises). They have long, erect flowering stems that may be simple or branched, solid or hollow, and flattened or circular in cross-section.
Irises generally grow well in most garden soil types, provided they are well-drained, depending on the species. Bearded irises thrive with full sun (6-7 hours), well-drained soil, and minimal watering once established. They require shallow planting, with rhizomes exposed or slightly covered.
