Hablitzia

Genus of flowering plants

Hablitzia tamnoides, or Caucasian spinach, the sole species in the genus Hablitzia, is an edible, herbaceous perennial plant, native to the Caucasus region. It is in the family Amaranthaceae, subfamily Betoideae, related to Beta, but unlike that genus, is a vine, climbing to 3 m or more tall in summer. Caucasian spinach is a long-lived herbaceous perennial climber. In fact it is one of the very few vines in its family - as one source put it, Hablitzia 'is remarkable and altogether anomalous in the order to which it belongs by its tall climbing habit’. It is also likely one of the longest lived plants in its family - one plant growing in Norrtälje, Sweden is reported to be over 50 years old. It is a diploid (2n=2x=18) with a basic chromosome number of 9.
