The next palm that I desperately want is Chamaerops humilis var cerifera. It may also be known as var 'argentea'. This is a blue/grey variety of the species and is slightly more robust. It appears to be able to tolerate more moisture and lower temperatures than the standard variety. I may however be a bit slower growing.
The image below is from a site offering a huge selection of palm seeds. The prices are about average but they are a good quality supplier. You can visit it here. As you can see, this palm is gorgeous!
This is a small clumping palm that grows to a maximum height of between 2.5m and 5m. Some sources say up to 6m depending on conditions (and likely if suckers are removed) The overall height often depends on the growing zone. This palm is rated from USDA zone 7b to past 11. Absolute minimum temperatures are about -15C (5F) but it may prove to be hardier. The lower the zone, the lower the final height of the palm (as a general rule for all species).
It is a great palm for a Mediterranean type climate as the name suggests. Full sun is best as well good drainage. In a climate like Vancouver, the crown may need to be protected in the winter to prevent any risk of rot. This is as simple as a bit of plastic over the top of the plant. Don't wrap too tightly as it needs room to breathe. A tent-like structure may be best. In the summer it is drought tolerant and a great plant for xeriscaping.
Now for a warning. This plant has two rows of spines along each leaf stem. As long as you pay attention you'll be fine. I wouldn't suggest it for anyone with young kids or pets unless you can ensure appropriate protection.
Hopefully I'll be getting a few seeds over the next week or so. Then maybe they'll be a decent size by the time I actually own a place! Still no full time job but I've found some small projects that will keep us going. At least until I can become a starship captain and explore the galaxy, leading the terraforming effort of uninhabited worlds across the cosmos. :)
