Re: Bearded Irises

Bearded iris will bypass vernaliation requirement for first year, but after that still need the vernalization to carry on for next year.

If I were going to grow bearded Iris in a warm climate I’d try rebloomers. They somehow bypass the usual requirements for bloom. Getting flowers more than once a year would make all the fuss of growing in a pot a little easier to take.

Maturity is measured as number of mature leaves. You may need to count 'leaf rings' on rhizome to get total. Usually in 10-15 leaves.
Bud set temperature seems to be in range of 15-21C minimum temperature for 5-6 days in a row.
Vernalization should be around 720 chill hours. Some cultivars are as low as 460.
