Nepeta subsessilis. This Fleuroselect award winning Catmint cultivar is a first year flowering perennial. The foliage forms a compact dome shape and is topped by pastel blue flowers on 20cm (8″) stems. Nepeta Blue Panther seeds are hardy to Zone 4, with blooms coming steadily from mid-summer to autumn. Expect flowers from June to September on the coast, possibly earlier once the plants become established. Use it in containers or as an edging to attract pollinating insects. Plant in full sun and space plants around 25cm (10″) apart.
How to Grow Nepeta Catmint
A relative of catnip in the mint family, catmint does not trigger the kitten-like behaviour in cats the same way catnip does. Although cats might graze on Nepeta leaves and flowers, it tends to not make them go crazy afterward.
Season & Zone
Season: Warm season
Exposure: Full sun
Sow seeds indoors in February and March, and transplant or direct sow in April and May. Can also be direct sown where it is to grow in September. Bottom heat will speed germination. Ideal temperature for germination: 21-27°C (70-80°F). Seeds should sprout in 10-20 days.
Sow on the soil surface or barely covered with perlite. Thin plants or transplant to 30cm (12″) apart.
This plant does very well in containers, raised beds, or borders in full sun to partial shade. After the main bloom, plants should be cut back hard to encourage a second bloom and tidy shape.
To save the summer catmint bounty, harvest when fully grown, and keep the plant picked regularly.
Usual seed life: 5 years.
Attracts pollinators, but repels aphids, flea beetles, Japanese beetles, ants, weevils, and squash bugs.
