PLANTS OF THE CLWA CONSERVATORY GARDEN

This is a dynamic plant list. As plants are reclassified we attempt to keep up with the changes. Not all the information in the Sunset Western Garden Book© is accurate for our area. In fact, the Sunset Western Garden Book© may indicate that a plant will grow here, and we have found that it does not do well. Conversely, just because a plant does not grow well in our garden does not necessarily mean that it will not grow for you.

The Conservatory Garden is a demonstration garden. The garden is in continual flux and experimentation. In this list you will notice that some plants have an asterisk (*). This signifies that these plants did not do well in our hard, clay soils. The lifespan of these plants is anywhere from one to three seasons. Plants that do not last this long have been deleted from our database.

As you utilize this offering from the Castaic Lake Water Agency keep in mind that these are only guidelines. Different soils, micro-climates, and cultural practices dictate to a large degree the success of an individual plant in a particular place. This list, in conjunction with the Landscape Education Workshops, provides valuable tools for homeowners and landscape professionals.
