Pheasant Tail Grass is a clumping large arching grass with colorful surprises throughout the year. To 30″ tall and a little wider the army green arching foliage takes on dramatic orange and red tints if given just a little stress. In summer fine tawny orange/brown glossy seedheads arch gracefully within the foliage. Full sun to very light shade in rich, well drained soil with consistent summer moisture- a little dryness and wham! You get those fiery tints. Requires a protected location in gardens, avoid full on exposure and cold winds. Its best application though is as a large graceful container subject. And the drainage adds to cold hardiness. Remove seedheads before they mature as it does like to seed around. Mulch for arctic weather. Moderate deer resistance. New Zealand.

A cool season grower it spends the winter in its freshest and lushest state by the onset of summer drought it has already gone dry dormant. To 8″ tall and spreading. 1′ spikes with tan flowers appear in late spring and remain erect until the entire plant goes summer dormant. With regular water and good drainage this grass will avoid summer sleep and remain green and lush. A common component of Willamette Valley Oak Savanna and losing ground to invasive weeds. Excellent underplanting for drought adapted shrubs, or for the garden/wild lands interface. It spreads quickly by seed- its from here, you should expect that so keep it away from highly manicured areas. Its habitat in the Willamette Valley has shrunk to almost nothing.

Golden Millet grass we love for its bright and shining appearance in shady woodlands. The upright growing then strongly curled leaf blades appear very much like ribbons. In summer stems rise and then arch with little round seeds. The entire plant is the same shade of glowing chartreuse. To 2′ tall and forming slowly expanding clumps. Shade to part shade in rich, well drained soil with light summer irrigation. Avoid blasting hot sun- it will bleach horribly to an ugly appearance. The combination of the soft, ribbon-like foliage and the airy seed heads is a great texture to counter balance the bold appearance of Hosta or Bergenia ciliata. Completely winter deciduous. Seeds around- and seedling come true and are easy to spot and they move very well. Dies away to nothing by midwinter- seldom even have to cut it back.
Of all the big, huge Miscanthus on the market this one appeals to us the most. Fine vertical then arching blades have edges lined in white.

But you can also leave it skeleton for winter interest and cut it back in spring. Regular summer water improves appearance and leads to blooms. Fully hardy. Winter deciduous. Japan.
A purely awesome form of Moor grass that we find indispensable at Xera. A strongly clump forming grass that has comparatively wide leaf blades margined heavily in cream. The effect up close is alternative deep green and yellow/cream vertical stripes. Very handsome. In summer 2′ spike rise. The stems are the exact color of yellow/cream that appears on the leaves, it gives great continuity to the whole plant. At the tips of these bright vertical stems are deep tan inflorescences. Exciting. Forms a clump to 18″ wide fairly quickly. Responds best to enriched soil that is fertile, drains well and light, consistent summer water which will lead to a much less thirsty plant in the long run. Roots go down very very far, and an established clump is somewhat difficult to lift and divide. But it can go many, many years before this is needed. Completely winter deciduous- cut back the vertical stems any time it is dormant. A fine texture for great contrast in borders or massed. Long lived and very hardy grass.
Most grasses in this genus native to North America really do prefer a hotter, longer summer than we have. But this one has surprised us and we are in love with it. Strongly clump forming evergreen grass with thin blue/green blades that rise to about 1′ tall.
