Both have grayish green leaves and require warm, sheltered positions making them both visually and culturally compatible. While the pineapple guava tends to be comparatively open and slender in habit the silktassel becomes a large spreading shrub, so room should be allowed for it to do its thing. If there is a sheltering fence or wall involved, with it not being desired to have the Garrya occupy a large space it might be possible to train it into a fan shape against the fence or wall, with the Acca (Feijoa) in front of it.

Thane, I can't think how I missed that thread when I searched. Most helpful. Eric -- I did read about the 'Pat Ballard' cultivar. The 'James Roof' I saw in the nursery had a wonderful leaf color and I read that it is somewhat darker than 'Pat Ballard,' but also that it is a bit less hardy. You two are so enthusiastic, I'm almost in the car on my way to the nursery! Thank you for the endorsement. Maro

Depends on what it is. Try King County Cooperative Extension. They will need samples.

Image by: Ian NartowiczSymphoricarpus alba (Snowberry)Autumn Interest At the end of the summer when the annuals have lost their lustre and most flowering shrubs and perennials have given up, the garden can still put on a good show. There are some plants that will flower well into autumn, some that will already have a showy fruit crop, and some that will dazzle with the colour of its dying foliage. Much depends on climate. In warmer areas it is easy to find shrubs that will flower into November or later, but it is less easy to get stunning red foliage in warm zones. Winter Interest When the days are short and snow is on the ground, a few shrubs still offer a bit of colour in the garden. Bright red berries are the obvious choice for colour in winter, but there are fruit in other colours, attractive variegated evergreens, and even the occasional flowering shrub. Again, different climates force us to look at different shrubs for winter interest. In really cold winters, flowers are impossible and foliage is restricted to needles. In warmer areas, attractive foliage may be lost in a mass of green and berries may be hidden by leaves.
