Colorful Combinations
Most primroses offer dainty blossoms held in loose clusters at the tips of long stalks. Other types hold their clusters of flowers so close together that they form tight balls of color, earning the common name 'drumstick primrose.' Candelabra primroses produce layers of blossoms along a bloom stalk and look stunning en masse. Several species delight gardeners with a lovely scent. Plant them near a path or low bench for the best chance to catch a whiff of their soft, subtle scent.
Primrose Care Must-Knows
With a diverse group of plants comes the need for diverse growing conditions. Even though many of these species prefer consistent moisture, they will not tolerate wet soil and will likely rot quickly when they get too wet. It's important to research the ideal growing conditions for your plant. With the alpine species of primrose, well-drained soil is a must. Many of the other types are native to moist alpine woodland settings, oftentimes growing near streams and even bogs. These woodland species don't like to dry out, so they love rich, humus-based soil that retains plenty of moisture. No matter what type you grow, all primroses have one thing in common: They like mild climates and dislike hot and dry summers, which quickly burn them out. Even if they are given all of their ideal conditions, they perform like an annual in hot weather.
Much like soil needs, sunlight requirements for primroses vary depending on the species. Make sure to find out exactly what type of primrose you're planting in order for it to thrive. Alpine species typically like more sun, but often perform just fine in part shade; however, many of the woodland types will quickly wilt when out in full sun and need part- shade to full-shade to flourish.

Primrose Companion Plants
One of the most elegant ferns available for your garden, Japanese painted ferns are washed with gorgeous silver and burgundy markings. Lady fern is equally elegant though not quite as showy. Either will add interest and texture to your shady spots. Closely related to each other, Japanese painted fern and lady fern are sometimes crossed with each other to create attractive hybrids. Unlike most ferns, these toughies will tolerate dry soil. And they will tolerate some sun if they have ample water.
The tall spires of a stand of foxglove, rising up in the garden in early summer, is a sight to behold. Most are biennials, that is, they need two years to bloom and then die in the fall. But if you can get a stand going, they'll reseed so prolifically it will seem they're perennials. To be successful with foxgloves, they must have rich, moist, well-drained soil and light shade, especially in the afternoon. (They'll do fine in full sun in the northern third of the country.) These tall plants also need to be out of any wind. Plants may rebloom if deadheaded after the first flush of bloom.
Named for the Greek goddess of the rainbow, iris indeed comes in a rainbow of colors and in many heights. All have the classic, impossibly intricate flowers. The flowers are constructed with three upright "standard" petals and three drooping "fall" petals, which are often different colors. The falls may be "bearded" or not. Some cultivars bloom a second time in late summer. Some species prefer alkaline soil while others prefer acidic soil.
