Description Boulevard Falsecypress, often sold as Blue Moss Cypress,is widely sold in the nursery trade for its soft, silvery blue green foliage and smooth narrow conic shape.

  Morphology:
Boulevard Falsecypress, also referred to as Cyano-viridis’ Cypress, is a dense, upright, broadly pyramidal symmetrical treeb which can grow from 10’-20’ tall but stay under 15’ wide. It bears awl-shaped, curving, finely pointed needles which are said to have a fluffy texture. Needles usually don’t exceed .5” in length. Under full sun conditions the needles turn a marked blue color during the winter months especially if the soil has sufficient magnesium. Some bronzing can occur during the winter if the site is windy.

Boulevard Cypress features a red-brown bark which is only noticed if the shrub gets quite large, or if the lower limbs have been pruned off which is a common approach when it is grown as a topiary plant.

  Adaptation:
This falsecypress variant prefers a moist, slightly acidic soil that has good drainage. While it is often used in a foundation planting surrounding a home it can eventually outgrow its space.

  Pests:
Root rot can be avoided by planting Boulevard cypress on well drained sites.
