The brilliant red spires of the Cardinal Flower can bloom for a month or longer and it is a nectar source for hummingbirds and swallowtail
butterflies. Occurring naturally in marshes and wooded stream banks, Lobelia cardinalis grows best in rich soils in full sun to
partial shade. Short lived, it is a prolific self-seeder, so it will replenish itself to form large stands of red blossoms!
Attracts Butterflies, Honeybees & Hummingbirds!

Cold, moist stratification. Start at least 5 weeks before outdoor night temperatures are reliably in the 10 C (50 F) range. Place seed on the surface of 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, place mixture on the surface
of pots filled with growing media. Seed needs light to germinate, do not cover after planting. 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.
Place seed on the surface of 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. Place seed on the surface of the growing mix
and label the pots. Place the pots 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.
