Aka Jerusalem Sage. This is a very compact but floriferous form of this evergreen perennial/subshrub. To 3′ x 5′ and forming a dome of thick gray/green foliage. In summer spikes extend and display yellow flowers in whorls around the stem. Very symmetrical and loved by pollinators. Surprisingly up close it is very fragrant reminding me somewhat of the sweet clovey scent of Dianthus. Long, blooming for 4-6 weeks. Full hot sun and rich to average well drained soil. Ideal on hot slopes. Light summer water aids vigor but it can take very dry conditions once established. Easy to grow, long lived plant. Mix with other hot sun dwellers and other mediterranean natives. Moderate deer resistance. Evergreen.
Wow, a species with golden leaves. Not variegation. How cool is that and it is a cool old gold color that the felted thick leaves glow. Rounded evergreen shrub to 30″ tall and 3′ wide forming a dome. In summer whorls of large yellow flowers surround the stems and kind of blend in with the foliage. Wonderful year round appearance. A plant I nominate as #1 Hellstrip plant of the year. It thrives in the heat reflected off the asphalt and it requires absolutely no water whatsoever when established. Plant for foliage and the flowers will follow. Glows in the dead of winter. Moderate deer resistance.
A really handsome and unique form of Jerusalem Sage. The large gray leaves are spongy and quilted and good looking all the time. This woody perennial forms a large spreading plant to 4′ tall and 5′ wide in full sun and rich to average well drained soil. Regular light summer water- to establish then drought adapted. Very drought adapted when established. Blooms June to August in our climate and makes a great paring with smaller low water full sun woody shrubs such as Cistus or Ceanothus. The whorls of soft yellow flowers born on upright stems have the sweet fragrance of cloves in close proximity. A very cool cut flower that lasts for more than a week in a vase. Loses some leaves in winter- gets them back quickly in spring. Wonderful on sunny hillsides. Moderate deer resistance. This form will often have a re-bloom with the return of fall rain. Give it room to spread out horizontally.

When you’ve given up all hope, When you think nothing will grow there enter this rugged, pioneering native to the rescue. Infamous for its weedy introduction have you ever had a close look at our own NATIVE populations? They yield truly showy flowers that are large cones with relatively large velvet purple flowers protruding. They make a great cut flower too. Found from the arctic to the tropics on North America. This form is genetically native stock. Full sun to quite a bit of shade in virtually any soil. Not as rambunctious as you would think but not a shrinking plant either. Very wild appearance and we like it. One of the first wildflowers that I recognized as a child, and when I was introduced much later to the weedy type I was sorely disappointed. Responds to regular water by blooming continuously. Reacts to withering drought by becoming limp and sometimes crisps. It always comes back. Mostly evergreen in our climate. To 6″ tall in bloom otherwise prostrate. Bees adore this plant. Aka Lanceleaf Selfheal. A good native weed. Oregon native plant.
I can’t imagine my garden in autumn now without this crazy late blooming blue, blue blue perennial. To 6 ‘x 6’ long stems terminate in clouds of bright blue guppy shaped flowers beginning in mid-October and continuing usually until the first hard freeze- often mid-December in the city. Part shade in deep rich moisture retentive soil. Kind of a quiet plant until autumn and then holy shit. Clouds of blue guppies people. Clouds of blue guppies. Often it gets yellow fall color simultaneously with this display. Incredible cut flower at a weird time of the year. Regular water all through summer. This plant gets big, big, big. Perfectly hardy to cold way below zero. So happy I found you Rabdosia now Isodon which sounds more like a freaking Dinosaur than a groovy late fall blooming perennial.
After almost 30 years of selling plants I can say that usually the first plant to go into a garden is Rosemary. And why not? It loves our climate. Its drought tolerant beyond measure and heck its even edible. And that fragrance. One thing you might not think of is winter flowers. This form from an ancient plant that has unique flowers.

Xera Plants Introduction
This beautiful, deep sky blue flowered rosemary we found planted at a 100 year old farmhouse in Milwauke, OR. The flowers are scintillating and this plant- installed in the early 1980’s, has proven longevity as well. To 3′ tall by 5′ wide eventually. Blooms appear unabated from autumn to summer. Vigorous evergreen shrub with an upright and then spreading habit. Full sun and no water necessary once established. It can take light, regular water in summer as well. Otherwise, it thrives on only what fall from the sky. A very showy winter blooming shrub for hot locations, south facing hillsides, adjacent to walls, asphalt anywhere another less heat durable plant would fry. Moderate deer resistance. Pungently aromatic and great for culinary use. Prune- if needed, in late spring following bloom. Blooms on wood from the previous season. This variety would make an admirable upright, clipped hedge. Named by and for our friend Carol. Thanks Carol. Salvia rosmarinus.

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.
