How to Grow
Plant in spring once the danger of hard frost has passed, ensuring placement in average, medium, well-drained soil. While Nepeta sibirica ‘Souvenir d’André Chaudron’ tolerates dry soils admirably, it is strictly intolerant of wet conditions, so excellent drainage is paramount for winter survival and overall health. Full sun encourages the best flowering, though partial shade is acceptable, especially in the hottest regions.
Maintenance for this tough perennial is generally low. Water regularly until the plant is established, after which its drought tolerance allows infrequent watering, particularly if sited in well-drained locations. Fertilizing is rarely needed; overly rich, moist soils can actually cause the plants to become leggy or overly aggressive.
To maximize bloom duration, shear the flower spikes heavily after the initial flush of flowers fades in early summer. This simple pruning step encourages fresh new growth and prompts more violet-blue blossoms later in the season. As one of the most cold hardy catmints available, Nepeta sibirica ‘Souvenir d’André Chaudron’ requires little special winter preparation beyond cutting back dead foliage in early spring before new growth emerges.
Landscape Uses
The recommended uses for Nepeta sibirica ‘Souvenir d’André Chaudron’ lean heavily toward creating relaxed, naturalistic plantings. Its tough nature makes it perfect for naturalizing areas where you want reliable, low-impact color and texture over widespread coverage. Use it along pathways or edges where its slightly aggressive tendencies can be managed or utilized to fill space quickly.
This Nepeta is also superb when integrated into traditional perennial borders or rock gardens. Interplant with plants that enjoy similar average to dry soil and full sun to create textural contrast. Due to its deer resistance, it serves as a beautiful, worry-free middle layer in mixed borders, allowing more delicate, susceptible plants to be featured closer to the view.
