Getting the Most from Your Sun Loving Perennial Garden
The great thing about using sun-loving perennials is you can have something blooming in your landscape from very early spring until frost. While it's tempting to make your shopping list based on things you see blooming in spring, you want to include perennials that provide color all through the growing season. You can go about this in two ways. The first way is to think about your garden on a monthly basis and take into account which month various plants bloom so you have several things in bloom every month. You'll also want to include perennials that bloom for a long period and/or that rebloom after the first flush of color such as Coreopsis, Phlox and Salvia. These plants provide many weeks of color.
You will be able to put together great combinations of sun loving perennials if you know when plants bloom, for how long and flower color. All of this information is included in the plant descriptions found on Great Garden Plants.
If you live in a region that gets hot and dry during the summer months, it's especially important to provide supplemental water to keep plants looking their best. Deadheading (removing old flowers) is also a great way to keep your perennials blooming for the longest time possible.
If your planting area receives six hours of sunlight during the sunniest parts of the day (roughly 10:00 - 4:00) then most sun-loving perennials will grow just fine there.
Drought Tolerant Perennials for Full Sun. When growing drought tolerant perennials, it is important that your drought tolerant perennials are established (not newly planted) before you turn off the water. Water well initially, and gradually hold back water as the roots mature and dig deeper for moisture.
Some colorful drought tolerant perennials include: Daylilies, Delosperma, Nepeta, Ornamental Grasses, Rudbeckia, & Sedum.
Ground Covers for Sun Nepetas, Geranium, Isotoma, and low growing Sedums.
Long Blooming Sun Perennials
The most colorful gardens are planted in sunny areas and they are choice sites for long blooming perennials. As you think about your flower garden design, try to use as many long blooming, sun loving perennials as you can. After all, most of us prefer to gaze out on a colorful carpet of flowers as opposed to a sea of green.
The combination of Ornamental grasses, Coneflowers, Phlox and Rudbeckia will bring many weeks of colorful enjoyment in summer. Add long bloomiong shrubs, such a, Knock Out Roses® combined with Geranium and Salvia for a fantastic long blooming combo. Use Coreopsis to extend early season bloom time.
