A first cousin to the better known aroid, arisaema is the lesser known aroid, arisarum. While arisaema has a distribution that is primarily North American and Asian, arisarum is primarily European. We planted our first arisarums back in 1994, and since then have tried quite a few and killed quite a few. The best species for our climate is Arisarum vulgare, a Mediterranean native, found naturally in the countries of Albania, Algeria, Baleares, Corsica, Crete, Cyprus, East Aegean Islands, France, Greece, Italy, Lebanon-Syria, Morocco, Palestine, Sardinia, Sicily, Sinai, Spain, Transcaucasus, Turkey, and the former Yugoslavia.

With such a wide range of occurrence, some forms are naturally going to be more adaptable to our Zone 7b climate than others. The star in our trials has been a 2010 Crete collection of Arisarum vulgare from near the town of Lakki. From a tiny rhizome piece, it has spread to a 3′ wide patch. Like its’ other cousin, arum, arisarum goes summer dormant, re-emerging in fall. All of the previous forms of Arisarum vulgare we’ve grown have flowered only in early spring, but this amazing form flowers quite well every fall, in addition to being incredibly vigorous. We’ve just dug some of our patch today, and will work on propagating them for a future PDN catalog under the name Arisarum vulgare ‘Lady Lakki’. Hardiness is Zone 7b and warmer.
