The pink Orchid seeds are a quest item given to the player during the Garden of Tranquility quest, by the gardener Lyra. In order to obtain the seeds the player must grow some onions in the vegetable patch north of Port Phasmatys after speaking to Lyra. The orchid seeds then need to be planted in Queen Ellamaria's garden behind Varrock Palace. After planting them they take 15-20 minutes to grow and are needed to complete the quest.
