Fall color in northern California
It may be a bit unfair to talk about zone 9/10 gardens this time of year, when most gardeners across the country are all too aware the first frosts are imminent or already happening. Little fear of frosts in favored gardens here in my town of Berkeley, and I exploit that to the maximum! This front garden has been tweaked over the past year to give the owners more lush color than previously, when it was mostly just the succulents. Just two species/3 additional plants were added back in November of 2011 to achieve this dramatic effect; tender perennials here, Thunbergera alata and Lotus berthelotii. The succulents quit blooming back in June/July, but the new plants still look like this in early October.
Another reason why I love gardening in the San Francisco Bay Area, even if we hardly ever get warm summer evenings...
