Poncirus trifoliata x Citrus sinensis ‘Rusk’ sweet orange
A hardy, evergreen citrus, also known as a Citrange or sweet orange, with the trifoliate leaves of its Poncirus
parent, but a bit larger and darker. White, sweetly scented flowers in spring. The orange fruits are small
with a reddish flush, and though somewhat less bitter than their Citrange relatives, still, are best used for juice
-- or simply as garden adornments. Plant in fertile, moist, well-drained soil in a sunny position. Plants are
tall, to 6-8 ft, vigorous, and frost hardy to USDA zone 7, though, as new growth is susceptible to frost, they
benefit from a protected site. Very nice in container with proper watering, just as soil becomes nearly dry.
A citrange, one of the oldest, developed in 1897 and named for J.M.Rusk, the first Secretary of Agriculture.
Who knew? Vigorous, small, evergreen to semi-evergreen tree, with Poncirus’ trifoliate leaves and thorns.
Fruit is orange flushed with red, seedless, and less bitter than a Poncirus, useful in juice, maramalades, etc.
Sun with regular summer water. Frost hardy to 0F, USDA zone 7.

A very special addition to any woodland garden, these evergreen ferns (yes, ferns) spread slowly to form
dramatic clumps of erect "tongues", to one foot tall, with copper-brown felty backsides and, in this form,
splayed leaf ends forming a broad, forked crest. Shade to part shade and even moisture. Frost hardy to 5F ,
mid USDA zone 7. A curiosity and a wonderful accent plant.

Quercus glauca japanese blue oak
Previously Cyclobalonopsis glauca. Beautiful oak, or oak relative depending on one's taxonomic belief, from
southeast China to Japan and Taiwan. This blue-tinted creature can reach 60-80 ft but seems content at 20 ft
in our part of the world. It had a brief stint of popularity in Portland in the 50s, then as far as we can tell,
became almost completely unavailable. The silvered bark and blue undersides of the leaves make this one of
the prettiest, medium-sized garden trees available for warmer climates. Not fussy but likes supplemental
summer water in dry climates. Good for sun or shade. Frost hardy in upper USDA zone 7. (The beautiful
specimen at the JC Raultson Arboretum in North Carolina was damaged severely but recovered quickly at
around -8º F.)
