Rosmarinus (Salvia) officinalis ‘Hardy Prostrate Form’

You might be surprised to find that some Rosemaries are tender to cold. In general the clones of prostrate forms are less hardy. This is cuttings from a low growing plant that has weathered the coldest winters of the past 10 years- so we’re confident its reliable. Mounding evergreen shrub to 2′ tall x 6 wide in time. The branches closely follow the contours of anything in its path and is fetching as it trails over rock walls, boulders, anything that gets in the way. Soft blue flowers almost year round but peaking in the winter. Little water needed once established in soil that drains. Water to establish or to speed growth. Wonderful herb for cooking. Takes the hottest, most blasting sites with no stress. Moderate deer resistance. Excellent on steep slopes as it will root where stems touch the ground- important for erosion control. Very pretty planted with yellow flowered Grevillea  juniperina ‘Molonglo’. Similar cultural conditions and concurrent bloom. Syn Salvia rosmarinus). Full hot sun.

Rosmarinus (Salvia) officinalis ‘Ticonderoga’

Hard to believe that Rosemary has been officially lumped into the genus Salvia. (Sigh). Its still a wonderful shrub and this variety delights us with the MOST luminous blue flowers that we’ve seen on a hardy variety. The effect is similar to the slightly tender cultivar ‘Tuscan Blue’. Each flower is luminous and they obscure the leaves for most of winter into spring. Upright growing cultivar that spreads with time. To 4′ tall x 4′ wide in short order. Full sun and soil that drains with little summer water once established. It will take moderate irrigation as well but we like to rely on the iron clad drought resistance of this culinary herb. Mix with Arctostaphylos, Grevilleas for a shrubby winter blooming party. Very easy to grow. Nice informal or even clipped dense hedge. Develops a handsome gnarled trunk with time. Moderate deer resistance. Salvia rosmarinus.

The blue flowers of the common and loved herb rosemary rivals that of Ceanothus and Lithodora. That is on certain varieties. Bloom typically begins in December and peaks in early spring continuing until late spring on the best varieties. This is the best variety for blue flowers. The obvious Salvia flowers on ‘Mozart’ are thick on the stems and are entirely dark blue- no interior dots of white or white splotches. Full sun and water to establish in average soil. Extremely drought adapted when established. This strongly arching shrub goes up to about 30″ and spreads to 4′ wide. Hillsides, the top of rock walls, containers subjected to reflected heat. Pork roast. Very good culinary use/taste for this plant. Hardy to about 5ºF. Good drainage improves cold hardiness. Tolerates the hottest places with no stress. Aromatic waxy resin will attach to your fingers. Blooms on wood from the previous season. Prune or harvest when needed after blooming has ended. Some deer resistance. Extraordinarily drought adapted. Great performance at the Oregon coast.

Rudbeckia hirta ‘Autumn Colors’

This short lived, very showy perennial is tough as nails. This strain enchants with huge flowers that are almost always single but come in tones from black to yellow, brown, orange, and red.. They immediately remind me of a blanket made by native Americans.  To 28″ tall ( compact ) with enormous flowers up to 5″ across. They come in a profusion from mid summer to early autumn. This strain has a natural life span of 3-5 years – but it does re-sow itself in open and opportune places. Open  soil that has been slightly enriched with compost / fertilizer. Full sun and regular water until fall rains take over. Mix with other sunset orange/ brown toned flowers. I pick the searing true red of Salvia ‘Royal Bumble’ as sell as the soft green spikes of Kniphofia pumila both will bloom simultaneously  with the Rudbeckia Excellent in summer containers and beloved for its long bloom time. Remove spent flowers for the first few rounds to encourage more bloom. leave the last round  to be pollinated and set seed. Excellent pollinator perennial. Regular water for the first season , less the following year. Some deer resistance.

Always on the lookout for cold and wet tolerant Salvias, this one has been a winner. Forms a woody structure topped by lush light green foliage. Beginning in July and continuing until frost hot magenta pink flowers appear again and again. Loved by hummingbirds  and all sorts of pollinators. Incredibly long blooming plant that gets by on a minimum amount of water each summer. Very well drained rich soil. Regular summer water speeds growth and makes a bigger plant that is ultimately hardier to cold. Laughs at the reflected heat of hellstrips. To 2′ x 2′ in a season. Regenerates from the roots following a hard winter. Cut back in early spring after all danger of frost has passed. Faithful deep soaks will propel it to bloom well into autumn.

Salvia barrelieri

We love North African Sage from the higher elevations of Morocco it performs beautifully in our climate. A rosette of low large sage green leaves is your first clue that this is a cool species. In summer 4′ spikes in whorls of blue and white flowers are spectacular. The blooms last a long time (6-8 weeks) and are awesome for cutting and including in huge, wild flower arrangements. Forms large clumps in time and there will be more and more flowers. Full sun, rich, well drained soil with regular summer water to establish after which light to little summer water is necessary in our climate. Very easy to grow and cold hardy. May self sow in open disturbed sites. Great Salvia but surprisingly difficult to find.

Thrives in the reflected heat of the hellstrip. To 1′ tall and 2′ wide in 5 years. Do not cut back until new growth pushes in spring.
