Nepeta sibirica Souvenir dAndre Chaudron - Catnip

Nepeta sibirica Souvenir d'André Chaudron forms a bush adorned with magnificent electric blue, tubular flowers, similar to a penstemon, but hardier.

This pretty perennial plant, native to Siberia, forms an upright tuft which is more compact than the species, adorned with vigorous stems carrying lanceolate leaves. The tubular, vivid blue-violet flowers, are larger and more abundant than usual, from May onwards.
Nepeta 'Souvenir d'André Chaudron' is hardy and vigorous and thrives in sunny locations in well-drained, rich, moist soil. It is one of the few that tolerates heavy soils. Plant it alongside campanulas, astrantias, and peonies, in an English-style mixed border or a romantic garden.
