Baby woodrose (Argyreia nervosa) is one of the more unusual vines to plant and grow. It is a perennial vine that produces tubular, 6-inch-long bright-pink to white flowers. Baby woodrose is also known as elephant climber, Hawaiian baby woodrose, silver morning glory and wooly morning glory. Native to eastern India, baby woodrose is cultivated in many subtropical and tropical regions of the world. You can plant baby woodrose seeds at any time of year just make sure you are planting fresh seeds that are no older than 6 to 9 months, according to online resource Shaman's Garden, as they begin to lose potency after that time and may not germinate.
Purchase baby woodrose seeds from a reliable vendor. If possible, check reviews of the vendor online to make sure you are purchasing the true baby woodrose seeds.
Scratch, nick or file off a small section on each of the baby wood-rose seeds. The seeds possess a very hard seed coat. Penetrating a section of the seed coat helps to hasten germination, advises Kada's Garden.
Place the baby woodrose seeds into a metal or ceramic bowl. Pour hot water over the seeds until they are just covered. Keep the seeds in the water until they start to swell, usually within one to three days. Once the seeds show signs of swelling, plant them.
Scoop a humus-rich planting mix into 3- or 4-inch diameter plastic pots. Make sure each pot is well filled to about 1/2 inch from the top. If you want to create your own planting mix, measure out two parts garden loam, one part compost, one part peat moss and one part vermiculite or perlite. Mix these ingredients together and then sift them through wire screening to remove any pieces of debris.
Set each pot into a bucket or basin that contains about 1 to 2 inches of water. This will help settle and moisten the mix. Once the mix in the pots is moistened, set each pot aside to drain.
Plant two to three baby woodrose seeds onto the mix in each of the pots. Use a chopstick or the eraser end of a pencil to push the seeds down 1/2 inch into the planting mix. Sprinkle about 1/2 inch of the planting mix over each of the baby woodrose seeds.
Place the pots near a light-filled source, like a south or west facing window that is not going to let any direct sunlight strike the pots. The temperature needs to remain above 65 degrees F. throughout the germination period. Keep the planting mix moist in each of the pots, until the seeds begin to sprout in approximately 10 to 21 days, depending on conditions.
