Elephant Creeper also know as Hawaiian baby woodrose
Argyreia nervosa
 
Elephant Creeper is a vigorous vine native to India, introduced world-wide. It has large, leathery heart-shaped leaves, which are white on the underside due to hairs. It is called elephant creeper because of the large leaves which look like elephant ears.
Hawaiian baby woodrose (Argyreia nervosa) is definitely not an infant in size, as its heart-shaped leaves can grow to 1 foot in length, and the vine may clamber to 30 feet. Its lavender-pink trumpet-shaped flowers are of more moderate dimensions, however, usually about 2 inches across and 3 inches long with maroon centers. When open, the woody seedpods look like miniature roses, explaining the plant's common name. Although similar to morning glory in culture, Hawaiian baby woodrose forms tubers that make it perennial in U.S.
 
How to grow :
 
o sow Elephant Creeper (Hawaiian Baby Woodrose, Argyreia nervosa) seeds, first scarify the seeds, soak them in warm water for 24 hours, then sow them in well-draining soil, keeping the soil moist and warm. 
Here's a more detailed guide:
1. Seed Preparation:
Scarification:
The seeds have a hard outer coat, so scarification (making a small nick or scratch) can help with germination. You can gently snip a small section of the seed coat away from the seed eye.
Soaking:
After scarification, soak the seeds in warm water for about 24 hours to help soften the seed coat and promote moisture absorption. 
2. Soil Preparation:
Well-Draining Mix: Use a well-draining potting mix, such as a combination of garden soil, compost, and sand. 
Coconut Soil: Some sources recommend using coconut soil for sowing. 
3. Planting:
Sow on the Surface: Sow the seeds on the surface of the soil and lightly dust them with a pinch of medium. 
Depth: Sow the seeds about 3/8" deep. 
Moisture: Keep the soil consistently moist, but not soggy. 
4. Germination:
Warmth: Place the pots or trays in a warm and sunny location, ideally between 70-85°F (21-29°C).
Time: Germination can take 2-4 weeks. 
5. Transplanting:
True Leaves: Once the seedlings have grown a few sets of true leaves, they can be transplanted into larger containers or directly into the garden. 
Space: For outdoor planting, space the plants 3-4 feet apart.

From seed to a mature, flowering Elephant Creeper (Hawaiian Baby Woodrose, Argyreia nervosa) plant can take approximately 6-8 months. 
Here's a more detailed breakdown:
Germination: Seeds typically take about 10-14 days to germinate. 
Seedling Stage: The seedling stage lasts for 2-4 weeks. 
Vegetative Growth: The plant then enters a period of vegetative growth, which can last 4-8 weeks. 
Flowering: Flowering and seed production usually occur 8-12 weeks after planting, leading to seed production in late summer to fall. 
Mature Plant: The plant will continue to grow and mature, eventually becoming a perennial climbing vine
