In most cases, yes. The bulbs can be planted outdoors in a sheltered, sunny spot in free drained soil and they will flower for at least a couple of years in succession in late spring though the flower spike may not be as large or densely packed. If you liquid feed them after flowering too this will help them to keep going from year to year.

Thanks! My home computer is still caput unfortunately (since mid October) but I will hopefully be on here more often soon.

Good
