Creeping Gypsophila filiformis is a low-growing alpine perennial groundcover that forms dense mats of delicate, thread-like foliage. It produces tiny, star-shaped white or pale pink flowers in summer that attract pollinators. This mat-forming plant is ideal for rock gardens, alpine troughs, and well-draining borders.

Growth Stages

1

Seedling

2-3 weeks

Tiny thread-like cotyledons emerge; extremely delicate, fine-textured foliage appears

Keep soil barely moist, not wet. Provide bright light. Avoid damping off by ensuring excellent air circulation.

2

Vegetative Growth

4-8 weeks

Develops dense creeping mats of fine, wiry foliage; spreads laterally along soil surface

Minimal fertilizer needed—too much causes lush growth and reduced hardiness. Water sparingly. Thin or thin seedlings to reduce competition.

3

Flowering

6-8 weeks

Produces abundant tiny, five-petaled flowers in white or pale pink held just above foliage in loose sprays

Deadhead spent flowers to encourage prolonged blooming. Can bloom for 6-8 weeks. Maintain dry conditions to prevent fungal issues.

4

Seed Development

3-4 weeks

Flowers fade and small papery seed capsules form; seeds mature and dry on plant

Allow some flowers to go to seed for self-sowing if desired. Collect seed pods before they shatter.

5

Winter Dormancy

4-5 months

Foliage persists but growth slows; plant remains evergreen or semi-evergreen depending on zone

Ensure excellent drainage to prevent rot during wet winters. No watering needed unless extremely dry. Protect from excessive moisture, not cold.
