Cross-Pollinating Drosera: Can Giant Staghorn and Cape Sundew Hybridize?

A grower asks if Drosera binata 'multifida extrema' (giant staghorn sundew) can cross-pollinate with Drosera capensis (cape sundew). Jeff Dallas explains that D. binata types generally require cross-pollination to set seed, though some temperate forms self-pollinate. Hybridization between D. binata and D. capensis is uncertain—it depends on chromosome compatibility. Sundews rarely hybridize naturally; known hybrids are often sterile.

Research is needed to confirm compatibility. If attempting, ensure both plants flower simultaneously and manually transfer pollen. However, success is not guaranteed, and resulting seeds may be inviable.

Good Growing!
