The enchanting Blue Flag Iris occurs naturally in sunny marshes, wet prairies and savannas and it is the official
provincial flower of Quebec. Blooming in late spring, it grows well in full sun to partial shade attaining two to three feet
in height. Iris versicolor is excellent for naturalizing in moist soils alongside pond edges and streambanks and it
will grow in water up to one foot deep!

Indoors: Cold, moist stratification. Start at least 5 weeks before outdoor night temperatures are reliably in the 10 C (50 F) range. Mix the seed with a slightly moistened, sterile, soil-less growing mix. Put this in a labelled, sealed plastic bag and store in a refrigerator for one day. The next day place this in the freezer for one day. Repeat this for one week, alternating between the fridge and the freezer. After stratifying, plant seed 0.32 cm (1/8 inch) deep in pots. Keep moist but not soggy and very warm (21 C - 70 F). When seedlings are 5 cm (2 inches) tall or more, transplant into the garden spaced 30 cm (1 foot) apart.
Scarify seed by rubbing between two sheets of sandpaper to scrape seed coat. Then plant seed 0.64 cm (1/4 inch) deep in a
prepared seed bed in late fall so that the seed overwinters and germinates naturally in spring.
In late fall through to mid-winter fill plastic pots with a slightly moistened, sterile, soil-less growing mix. Scarify seed by
rubbing between two sheets of sandpaper to scrape seed coat. Then plant seed 0.64 cm (1/4 inch) deep in pots and label the pots.
Place them outdoors in an area where they will experience the snow and cold of winter. The seed will germinate in the pots in
spring as the weather warms up. Be sure to water the pots regularly in spring and once the plants are 5 cm (2 inches) tall,
transplant them into your garden.
