Nursery contributed plant descriptions

Nice heirloom perennial forms a clump 2’ high and wide with stems topped by butterfly attracting VIOLET frothy flower heads 3-4” across; softly fragrant summer thru fall. Full sun in the north and on the coast and part shade in hot sun areas; regular water and loamy well drained soils will make this plant happy! Ignored by both snails and slugs…go figure! Reseeds politely which is good because it can be short lived due to its intense flowering!

Related to the Bellflowers but with the look of a lovely blue Jupiters Beard this 2-4' Mediterranean native should be protected or treated as an unaggressive self-sowing annual; either way you?ll enjoy its show in blue. S/M

With a common name like “Throatwort,” you can see why this beautiful plant is not well known. Like a lavender-blue “Queen Anne’s Lace,” this Mediterranean perennial bears large, dense domes of intricate flowers dotted with tiny white “pins.” Lightly violet scented, the 3-4” clusters on upright stems look lovely in any garden & make trés romantic cut flowers. Easy to grow & vigorous. Blooms mid-Summer till Fall, just in time for the butterflies. Deadhead & give good drainage. To 3’ x 2’ & may self-sow.
