Gardeners' Notes:

This plant grows beautifully in the coastal chaparral areas of california. Because the plant is small, we supplement with a deep watering once or twice a month during the driest hottest months. The soil is very sandy. Once it grows a bit, expect it will do just as well with the available moisture coming off the ocean.

I planted three LongJohns 18 months ago in average soil (more clay than sand) approx 10 feet apart, next to our bamboo fence on the street side. Our late spring and summer weather is cool with many foggy and windy days. However, the LongJohns have thrived and are now constantly in bloom and approx 6.5 ft tall each. They are beautiful against the bamboo fence and very striking to look at. The hummingbirds and bees love them. The LongJohns also work as cut flowers for several days. They make incredible vase displays. I highly recommend this grevillea for showy garden plant. I will post pix soon.
