Drosera esterhuyseniae x slackii

A cross between two Cape sundews from opposite ends of the moisture spectrum. D. esterhuyseniae grows on dry, well-drained sandstone slopes in exposed fynbos and goes dormant in summer, unusual behaviour for a sundew. D. slackii grows in permanent peaty seepages along mountain streams and stays active year-round. Their ranges overlap in the Hottentots-Holland and Kleinrivier mountains near Hermanus.

Both parents are endemic to the mountains of the Western Cape, South Africa, part of the Cape Floristic Region. D. esterhuyseniae favours higher-elevation slopes moistened by coastal fog rather than standing water, while D. slackii sits in creek-side seepages that never dry out. The hybrid inherits something from each side.

Compact rosettes with broad leaves, yellow-green with orange-red tentacles. Faster-growing and easier to cultivate than either parent. Flowers are large, pale purple, but rarely produced.
