I would suspect there aren't a whole lot of people on this forum growing that plant. You might want to check out the California Gardening Forum if it's a plant commonly grown in your state or your part of CA.

Like most other perennials, the bloom period is seasonal, not all summer long. Deadhead, keep well watered and fertilize in late winter or early spring. Contrary to what you may have read, fertilizing IS recommended but avoid any high phosphorus blends (middle number). A well-draining, quite organic soil in full sun is ideal.
