We were not able to attend the California Spring Trials to see all of the new perennials that will be available this year. We have been reviewing websites, catalogs, and other materials to come up with some exciting new selections for you to look out for in your local garden center or online. If you’re looking for something new for your garden some of these perennials might be of interest to you. The clematis is by far my favorite, so be sure to read about it.

Sparky® Blue Clematis
We mentioned this was our favorite new perennial. Sparky Blue Clematis is from Proven Winners and it is not your run-of-the-mill clematis. It blooms earlier in spring than other clematis, and the flowers look like pinwheels. This clematis also comes in pink and purple, but we liked blue the best. You have not seen clematis flowers like this before. The center of the flower is yellow. The flower appears on elegant, slender stems from among delicately toothed foliage. The plant starts blooming in mid-to-late spring and flowers continue to pop out through early to mid-summer. Try growing this on a trellis in your perennial garden or planting it along a fence or other latticework. The plant does need support from plant time onward, so make sure you plant it near a rail, deck, or trellis. It is easy to grow and pruning is not needed. This plant is also disease resistant and hardy in zones 5 – 8.
