Germination
7-14 daysTiny seedlings emerge with delicate cotyledons; very fine, hair-like appearance
Keep soil consistently moist but not waterlogged. Provide warm temperatures (70-75°F). Use well-draining seed-starting mix.
Seedling
2-3 weeksFirst true leaves appear; silvery tint begins to show; plants remain small and delicate
Maintain bright light to prevent legginess. Thin seedlings if overcrowded. Keep soil lightly moist. Avoid fertilizing yet.
Vegetative Growth
4-6 weeksPlant develops more foliage and trailing stems; silvery coloration becomes pronounced; stems elongate and cascade
Begin regular watering schedule. Apply diluted balanced fertilizer every 2-3 weeks. Pinch back tips occasionally to encourage bushier growth if desired.
Trailing & Mature
Ongoing until frost or year-round in warm zonesLong cascading stems fully developed with abundant silvery foliage; plant fills containers and spreads as groundcover
Maintain moderate watering. Fertilize monthly with balanced or slightly lower-nitrogen fertilizer. Remove any dead or damaged stems. Prune for shape if needed.
Decline (in cold climates)
Varies with climateFoliage may turn brown and plants die back after first frost (zone 9b and colder)
Bring container plants indoors before freezing temperatures. Or allow to die back and reseed following spring in warm climates.

Fun Facts
- 🌱 Silver Streamer is also commonly called Dwarf Morning Glory or Trailing Dichondra, and was originally discovered in desert and semi-arid regions of the southwestern United States and Mexico.
- 🌱 The silvery coloration of the foliage is due to fine, hair-like structures on the leaf surface that reflect light, similar to the silvery appearance of Dusty Miller—a natural adaptation to intense desert sunlight.
- 🌱 In warm climates, Silver Streamer can self-seed readily and may reappear the following spring without replanting, making it a low-maintenance perennial or semi-perennial groundcover.
