Red Warty Growth on Cape Sundew Stem: Aerial Roots

Edmund in Oahu sees red, wart-like bumps on his D. capensis stem, wonders if it's flowering or disease. Plant in partial sun, distilled water (switching to tap per mom's order), 1:1 peat/perlite.

Expert Identification: Normal Aerial Roots

Jeff Dallas identifies them as adventitious roots. In native South Africa, D. capensis scrambles on hillsides and uses these roots to anchor between rocks.

Critical Warning: Tap Water Will Kill It

Minerals in tap water accumulate and eventually kill carnivorous plants. If forced to use tap water temporarily, top-water every time and flush the pot thoroughly (over sink or outdoors). Better: collect rainwater (windward Oahu), use a ZeroWater filter, or ask school science lab for distilled water.

Good Growing!
