 The flowers are across, orange-red, with a pale central line on each tepal; they are produced from early summer through late autumn on scapes of ten through twenty flowers, with the individual flowers' opening successively, each one only lasting one day.The fruit is a three-valved capsule long and broad which splits open at maturity to release the seeds.Both diploid and triploid forms are known in the wild, but most cultivated plants are triploids which rarely produce seeds and primarily reproduce vegetatively by stolons or division.
