Approximately 100-110seeds per gram. Rosa acicularis LOT#FWR10075 The Wild Rose is native to Alberta and blooms starting in late May and lasting until early August. The fragrant flowers are bright pink with petals 3-5 cm in size and can be used for the manufacture of perfume. The Wild Rose is classified as a multi-stemmed deciduous shrub (bushy shrub) and can be found almost everywhere in Alberta. It has dark green foliage throughout the season. The serrated oval compound leaves turn yellow in fall. The fruits are showy scarlet hips displayed in late summer. It can grow upwards to 1.5 m (5 feet) tall and has "bristle like" branches. The larger stems are densely covered with small prickles with the occasional thicker thorn. Best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting birds, bees and butterflies to your yard.
Before growing roses from seed, rub the seeds lightly sandpaper- just enough to scuff the hard seed coating. Rose seeds need to go through a period of cold moist storage called “stratification” before they will sprout. Plant the seeds in a shallow growing tray, approximately 2-3 seeds per hole 6 mm (¼ inch) deep in a seed-planting mix. Then place them in a refrigerator for 6-8 weeks. Place under grow lights or in a sunny window until the seeds sprout. Once they have their first set of true leaves, transplant seedlings into larger pots. Seeds can be directly sown in the fall. These plants don’t usually require much assistance once established. Generally wild roses prefer full sun and well-drained soil although some will manage in partial shade. In the spring, cut back deadwood but leave living canes as they flower on older stems.
