Nepeta tuberosa L. is a tuberous catnip species from the Iberian Peninsula, Morocco, and Algeria, with slender upright spikes of purple flowers in dense verticillasters with pinkish-grey bracts. The spikes only branch on rather strong cultivated specimens, but rarely in habitat. All parts of the plant are covered with fine hairs, adding a silver tone to the leaves as well. The fleshy roots have notable constrictions every 1- 1.5 cm.
The plants shown here were grown by Martin Bohnet from seed donated in EX01 by Johannes-Ulrich Urban, collected in Portugal. They have no effect on Martin's cats and only have a barely noticeable scent. The smaller specimens have survived a rather mild German winter outdoors; the bigger one in photo 2 is potted and was kept barely frost-free.
