About Columnar Italian Cypress

Cupressus sempervirens 'Stricta' · also called Mediterranean Cypress, Pencil Cypress · flowering

Columnar Italian Cypress is the iconic narrow, dark-green column of Mediterranean landscapes, reaching great heights while remaining extremely slender. It thrives in hot, dry climates and is a classic feature of formal gardens. Not listed by the ASPCA as toxic; considered low-risk to pets.

Ideal humidity: 30-50%

Watch for — Aphids: Aphids can cluster on new growth. A strong water jet or insecticidal soap resolves most infestations.

The watering schedule, season by season

Columnar Italian Cypress flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for columnar italian cypress is when the top 5-8 cm of soil is dry, roughly every 14-21 days once established, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Highly drought-tolerant once established, making it ideal for Mediterranean-climate and low-water gardens. During establishment (first 1-2 years), water deeply but infrequently. Overwatering is the most common cause of decline.
