Sensitive Plant Mimosa Pudica Seeds

Thank you for choosing Sensitive Plant / Mimosa pudica seeds — this little “shy plant” is such a fun grow! Its leaves fold when touched, and in warm weather it can bloom with tiny pink puffball flowers.

Mimosa seeds have a hard shell, so a little prep makes a big difference. Before planting, soak the seeds in warm water overnight (about 12–24 hours). If you notice some seeds don’t swell, lightly scratch one side of the seed coat with a nail file or sandpaper, then soak again. This helps water get inside and speeds up germination.

These plants love warmth. Start seeds when temperatures are consistently warm, or begin indoors and move them outside only after nights stay above about 18°C / 65°F. Cold soil will slow them down a lot, so think “tropical vibes.”

For planting, use a light, well-draining potting mix (something airy like potting soil mixed with perlite or sand). Sow each seed about 5 mm (¼ inch) deep, cover lightly, and mist the surface. Keep the soil gently moist but never soggy. A warm spot with bright light is perfect — ideal germination temperature is around 22–28°C (72–82°F). Most seeds sprout within 1–3 weeks, so don’t worry if they take a little time.

Once seedlings pop up, give them lots of brightness. Morning sun or full sun will help them grow bushy instead of tall and floppy. Keep watering lightly whenever the top of the soil feels dry. If the soil stays wet too long, roots can rot, so drainage is your best friend here.

When your seedlings have a few true leaves, you can transplant them carefully. Mimosa roots are delicate, so try not to disturb them much. They do beautifully in pots, and that’s often the easiest way to keep conditions just right. If you want a fuller plant, pinch the top tip when it’s about 10–15 cm tall — this encourages branching and a nicer shape.

Feeding is simple. Mimosa doesn’t need heavy fertilizer. A gentle, half-strength balanced feed once every few weeks in the growing season is plenty. Too much fertilizer, especially nitrogen, can make it leafy but not very flower-happy.

A couple quick notes: if leaves don’t close when touched, it usually means the plant is stressed (too cold, too dry, or not enough light). Warmth and bright sun fix that fast. Yellowing leaves usually point to overwatering. Let the soil dry a bit more between waterings and make sure your pot has drainage holes.

With warmth, sun, and gentle care, you’ll see that classic leaf-folding movement and maybe even those cute pink flowers
