    Helianthus maximiliani - Maximilian's Sunflower

    SKU: C14650



    One of the last flowers to bloom in the season, Maximilian's Sunflower grows to great heights becoming profusely covered with hundreds of bright yellow flowers in the late fall. The lance-shaped gray-green foliage is quite attractive throughout the summer and the flowers make great fresh cut flowers for autumn bouquets. Helianthus maximiliani is a tremendous food source for both birds and butterflies in the late fall.

    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.

    Outdoors: Plant seed 0.32 cm (1/8 inch) deep in a prepared seed bed in late fall so that the seed overwinters and germinates naturally in spring.

    Outdoors Alternative: In late fall through to mid-winter fill plastic pots with a slightly moistened, sterile, soil-less growing mix. Plant seed 0.32 cm (1/8 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.
