|Nepita(catnip) is in bloom now. I think I saw a VERY light blue one and then another one that is brilliant dark blue.
If this is true, what is the name of the very dark brilliant blue one?
|I am familiar with three Nepeta cultivars:
Nepeta ? faassenii 'Walker's Low' grows into a mound of lavender-blue flowers and aromatic, grayish green leaves up to 2 feet tall and 3 feet wide is great as edging or in a border, herb, or rock garden. It is an easy to grow, prolific bloomer that seems to be deer resistant. It blooms the whole summer and tolerates some shade.
Nepeta ? faassenii ?Dropmore? - This cultivar is a clump-forming perennial with toothed gray-green leaves and larger flowers than the hybrid. It flowers profusely and long, especially if sheared. The profuse, large blue flowers attract bees and butterflies. It is long-blooming if sheared. The only downside is that the aromatic foliage is sometimes attractive to cats.
Nepeta Little Trudy is a new compact catmint, with the cultivar name 'Psfike'. It only reaches 8 to 10 inches tall and 12 to 16 inches wide, the perfect size for containers, bed edges, or other small nooks and crannies. It features the same silvery foliage and summer lavender blooms that we know and love, and thrives in full sun to partial shade and well-drained soil.
Nepeta ?Blue Ice? is a new introduction of catmint that offers several improvements over the older, more commonly grown Nepeta x faassenii cultivars. ?Blue Ice? is extra compact, reaching only 6-10 inches tall and bearing numerous spikes of dainty ice-blue flowers over attractive, aromatic, gray-green foliage.
There is also Nepeta racemosa 'Blue Wonder' which has dark blue flowers.
I hope one of these is the plant you saw!
