Shadblow Serviceberry Seeds
The Shadblow Serviceberry is a shrub or small tree that grows 25 to 30 feet tall and 15 to 20 feet wide. It is native to Eastern North America. The Shadblow Serviceberry is one of the earliest native trees to flower in the spring. Its fragrant beautiful white flowers bloom before leaves appear on other trees in the spring. Its flower nectar attracts butterflies. Flowers give way to edible purple black berries in early summer. Shadblow Serviceberry berries are used in making jams, jellies and pies. The berries are eaten by songbirds, bluebirds and robins. The Shadblow Serviceberry is a stunning fall foliage tree with orange, gold, red and green leaves.
Growth Rate: Slow to Medium
Soil Type: Tolerant of wide range of soil conditions. Prefers moist, well-drained soil.
Zones: 3 to 8
Germination Range: 60-80%
Stratification Requirement: Seed requires 30-60 days warm stratification followed by 90-120 days cold stratification.
Indoor Planting: If your seeds require stratification or scarification – do the recommended pretreatment before planting indoors. Planting Instructions: Fill a container with seed starting mix to about ½ inch from the top. Place your seeds 1 inch to 1 ½ inches below the soil surface. Gently water your seeds to keep moist, not soaking wet. Heat & humidity is critical for germination. Germination may occur in 1 week or as long as 3 months (depending on the species). Place the seed container on a heat mat under growing light(s). Keep your growing lights on 14 hours per day. Keep your heat mat on 24 hours per day. Once your seeds germinate, move each seed into its own container under the growing lights and on the heat mat. Keep your seedlings indoors for 2-3 months before transplanting outdoors in the spring (May to June).
Outdoor Planting: If your seeds do not require stratification: the best time to plant tree and shrub seeds outdoors is after the last frost in your area (spring). In the Northern states – the best time to plant seeds outdoors is from May to June. If your seeds require pretreatment: you should plant your seeds outdoors before the ground freezes in your area (late September to early November). Your seeds will naturally stratify during the cold winter. Germination usually occurs in May or during the spring season.
