About Alocasia 'Purple Cloak'

Alocasia 'Purple Cloak' is a compact hybrid cultivar named for its near-black, deep-purple petioles and stems, which contrast sharply against glossy, arrow-shaped dark green leaves. The purple pigment often bleeds faintly into the leaf margins and shows clearly on the underside of each blade, giving the plant a moody, richly coloured presence despite its modest size. Its exact parentage is undocumented, as is common for many hybrid Alocasia cultivars circulating in the trade, but it is widely grown for the stem colour rather than any variegation. It keeps a tidy clumping habit that suits smaller collections better than the genus's larger-growing species.

Before You Buy

Species-specific things to check when evaluating a listing

  • Check the corm/base is firm, not soft or mushy
  • Confirm the petiole colour is genuinely dark purple to near-black rather than plain green, as naming consistency varies between sellers
  • Inspect for spider mites on leaf undersides, a common Alocasia pest

Colour Without Variegation

Not every desirable Alocasia trades on a white or gold break in the leaf — this one earns its keep purely through stem and underside colour, which is a different kind of drama entirely. As a hybrid cultivar its lineage isn't formally documented, which is true of a great many named Alocasia selections in circulation. Judge it on the plant in front of you rather than any claimed parentage.

Market Trend?Recent 4-week median vs. the prior 4 weeks. A rise only counts as 'Rising' when it's corroborated across the sample (not just one high sale) and confidence is decent — otherwise it's labelled a 'Spike'. Declines aren't treated as bad news: they're the expected trend as stock gets propagated.
