about 30 capsules very small seeds in capsule To grow butterfly bush (lilac buddleja) from seed, the seeds should be sown indoors in seed soil in February-April, just before the last spring frost. The seeds are light-germinating and should only be pressed lightly against the moist soil surface, not covered. After germination, the plastic should be removed and the plants should be placed in a bright and cooler place, before being transplanted into potting soil and finally planted outdoors when the risk of frost is over.
