|I see 'old' cypresses that look almost like pencils (12-18|
|There are a couple of cypresses that have the growth habit you describe. There's also a Juniper that might work for your situation:
BLUE ITALIAN CYPRESS (Cupressus sempervirens 'Glauca') is an outstanding classic Mediterranean cypress with attractive blue-green foliage. An ideal conifer to dominate a landscape with its densely branched, narrow columnar form. Evergreen. Full sun. Fast grower to 60 to 80 feet tall, 2 to 3 feet wide; can be larger.
SWANE'S GOLDEN ITALIAN CYPRESS (Cupressus sempervirens 'Swane's Golden') A very narrow, columnar form with magnificent bright golden-yellow new growth that retains its color throughout the season. Great evergreen screen, windbreak, or large hedge. Full sun. Slow grower to 15 to 20 feet tall, 2 to 3 feet wide.
SKYROCKET JUNIPER (Juniperus virginiana 'Skyrocket') This stately, columnar form makes this probably the narrowest juniper available; resembles a skyrocket! Durable and versatile, best grouped to form a colorful bluish-gray screen or garden accent. Full sun. Fast grower to 15 to 20 feet tall, 2 to 3 feet wide.
Hope one of these plants is just right for your landscape.
