|I. grandulosa (see I.orientalis) comprises a group
of medium to large clump-forming perenials, with
woolly buds and turning to large daisy like
orange-yellow flowers with many narrow ray flowers
3-5 inches across around a central disk.
They prefer full sun, well drained soil and are
cold hardy. Moisture needs vary depending upon
species. Propagate by seed, or by dividing in
spring or fall.
