In the heat of summer, bright lavender pink daisies cover the pretty and wild Tennessee coneflower. This rare species is only native to the State of Tennessee and is on the United States Federal Endangered Species List. For this reason, the wild-type species is typically only available at specialty plant nurseries and seed suppliers.
This hardy herbaceous perennial wildflower is clump-forming and has linear, fuzzy green leaves. In summer it produces mauve-pink daisies with orange-brown central...

(Rocky Top Tennessee Coneflower, Tennessee Coneflower)
Bright lavender pink daisies cover this compact Tennessee coneflower in the heat of summer. The vigorous and heavy flowering 'Rocky Top' is tough, beautiful and readily found in the garden trade. The parent species, Echinacea tennesseensis, is only native to the State of Tennessee and is on the United States Federal Endangered Species List. For this reason, it is typically only available at specialty plant nurseries and seed suppliers, though 'Rocky Top' is easily obtained.
(Calico Cactus, Engelmann's Hedgehog Cactus, Hedgehog Cactus)
Cloaked in ferocious spines, this low spreading cactus is so adaptable it can be grown just about anywhere in the American southwest and even some states further north. This beautiful mounding cactus is from the southwestern United States and northwestern Mexico, with populations occurring from sea level up to very alpine locations. It varies widely across its native range, resulting in the naming of several subspecies and varieties.
Engelman’s cactus is composed of many cylindrical stems...

(Hardy Hedgehog Cactus, Lace Hedgehog Cactus, Reichenbach's Hedgehog Cactus)
Fabulous flowers and a short, tidy habit make this a highly rewarding cactus for containers and rockeries. Rare in the wild, it occurs in dry, rocky scrub and grasslands from southeastern Colorado to northern Mexico. It is noted and named for its interlacing, starry clusters of stem-hugging, flattened spines.
The small, upright, football shaped stems of lace hedgehog cactus are initially single. Over time they produce pups and create clumps. Mature stems produce lots of striking pink, lavender-pink...

(Giant Viper's Bugloss, Pine Echium, Tree Echium)
Small, unassuming rosettes of linear, dusty green foliage develop floral columns lined with small violet-blue flowers that burst upward to heights of 8- to 10-feet (2.5- to 3.25-meters). A native of the dry inland laurel forests of the Canary Islands, tree echium survives as a half-hardy biennial. It is a spectacular plant in bloom and has become endangered in its native habitat, though it is very popular in cultivation.
Dense rosettes of linear, silvery or dusty green foliage overwinter and...
(Common Viper's Bugloss)
Native to Europe and western Asia and a common roadside weed over much of the United States, this bristly biennial is grown for its tall summer-long spikes of azure flowers.
First-year seedlings of this hardy biennial form broad rosettes of large, rough, lance-shaped leaves. The following growing season, long steeple-like clusters of small funnel-shaped blooms are borne on stout upright stems that continue to appear from late spring to late summer. Flowers are typically pink aging to blue, but...

(Blue Bedder Bugloss, Common Viper's Bugloss)
A compact, blue-flowered selection of a bristly Eurasian biennial, 'Blue Bedder' blooms its first year if sown in early spring.
Rosettes of rough, lance-shaped leaves give rise to conical clusters of small, violet-blue, funnel-shaped blooms on calf-high stems. Seedlings started in early spring bloom from early to late summer; those started in fall bloom from late spring to midsummer the following year. Plants usually self-sow abundantly if not deadheaded.

A pleasant upright-shaped shrub with gently arching branches, the Quicksilver silverberry glistens with silvery gray-green foliage and red fruits. A hybrid originating in England as a chance seedling, 'Quicksilver' is a fast-growing deciduous shrub.
The thin branches have thorns. At first, the branches are held upright, but as they lengthen and carry more weight they begin to arch. In early spring, the oval leaves emerge with a whitish silver hue. They mature to silvery gray-green. In late spring...
