Canary Island Date Palm (Phoenix Canariensis) - This date palm tree originated from the Canary Islands; hence the name. It is hardy down to 20 degrees Farhenheit and will remain a perennial plant in temperatures warmer than that. If temperatures get 20 degrees or below, the Canary Island Date Palm may die or sustain frost damage that is unattractive. It can be slow to recover from this type of damage. This temperature range is typically indicative of USDA 9A and above to not sustain frost damage to Phoenix Canariensis.
The Phoenix Canariensis Canary Island Date Palm is used as a skyline border, roadside landscape, oasis effect, and other landscaping purposes. It grows best in full sun with deep, but infrequent irrigation. Phoenix Canariensis can reach 30 feet tall when directly planted outsided in full sun. The Canary Island Date Palm prefers uniform soil, but either sandy soils or loam is fine to use with a pH of 5.6 - 8.5. Canary Island Date Palm is considered to be deer resistant.
This is a spectacular palm for landscaping large areas but can also be used in confined areas in urban landscapes. Plant in a deep pot that provides plenty of room for the taproot and provide plenty of light. This date palm tree is drought tolerant and looks best when planted in full sun. Don't place young palms too close to walkways where their sharp leaf spines might injure passersby.
Place the Phoenix Canariensis seeds in a sterile medium which is only barely moist, but never too wet at approximately 1/2 inch deep. The soil you plant the date palm tree seed in should almost feel dry to the touch. Nevertheless, don't be tempted to add more water. Seal the seeds in an airtight container (such as a plastic sandwich box (recommended)) or a plastic bag. Place it in a warm-to-hot position; say above the hot-water tank. Temperatures of 90 degrees Fahrenheit are ideal. Inspect the seeds daily. Many species germinate in as little as one or two weeks, but some may take quite a bit longer. When a root appears, carefully put the seeds into well-drained compost (e.g. 50/50 standard potting compost and coarse grit), and keep warm until the shoot appears. When the shoot appears place the palm in a warm, light place. If your room temperature is fairly cool, be very careful not to over-water as the roots of some palms (even the humble date palm) will rot if the compost is kept wet when the palms are not actively growing.
