Pineapple Lilies are a group of summer flowering perennials that are truly a show stopper. Our guests to the garden keep asking about this unusual plant. In the early spring this bulbous perennial's leaves appear and make you ask "What is it"? Then the long flower stem starts to appear sporting blooms that really do resemble the fruit of a pineapple. It is winter and summer hardy, but does seem to appreciate afternoon shade.
You can find this plant in the entry garden and just outside our outdoor classroom in the boulder garden.
This herbaceous hibiscus has 4 - 5" oxblood red flowers with very dark green foliage with red veins and grows as a dense mound 24 to 30" under Central Oklahoma conditions. It is drought tolerant but supplemental watering increases flowering under stressful conditions. Flowers best in full sun.
You can't miss the showy display in our pavilion garden. It blooms all season long until late fall and then dies back to the ground until the next spring. What a great surprise in spring to see its rebirth and by the beginning of June those wonderful flower buds appear.
Supertunias are a vigorously trailing species of an ever-blooming, long living petunia from Australia. They will provide long term color in full sun areas throughout the season, and can grow nearly an inch a day. They are ideal for baskets, beds, balconies, and combination plantings. Supertunias are very heat and drought tolerant once established in the ground or pot.
Supertunias do not need to have their dead flower heads removed to continue flowering and they are not leggy. They grow fast and therefore need ample moisture and fertilizer.
Check out our Entry Garden and other garden areas as well to see amazing displays of Supertunias after our long hot summer - absolutely beautiful.
Like all plants in the Endless Summer Collection, Twist-n-Shout produces abundant blooms on both old and new wood all summer long. Lacy deep-pink centers are surrounded by gorgeous blossoms of pink or periwinkle blue, depending on soil type. Sturdy red stems and glossy deep green leaves turn red-burgundy in fall to offer year-round interest in the garden.
Easy to care for and hardy to zone 4, Twist-n-Shout is an elegant stand-along specimen, dramatic in combination with other plants, and compact enough for containers.
You can find these beautiful plants welcoming you at the entry of our barn.

Nothing can compare in mid summer months to the heat loving crape myrtle, especially the 'Whit' cultivar crape myrtle series. Lagerstroemia indica is the scientific name for the crape myrtle and Dr Carl Whitcomb has created eight different varieties. Three of his famous cultivars can be seen at the Linnaeus garden - Pink Velour, Red Rocket, and Rhapsody in Pink.
Most crape myrtles are hardy through zone 7, but Dr Whitcomb's creations are hardy through zone 6 (Tulsa zone is 6b), and all have high mildew resistance.
Pink Velour was picked as a "2003 Oklahoma Proven" plant, which proves its hardiness for Oklahoma weather. It has distinct dark wine foliage which peaks in spring and then explodes with shrill pink flowers in mid-summer.
Red Rocket has cherry red flowers and is the fastest growing "Whit" red and may have more repeat blooms then the famous Dynamite Crape Myrtle which was chosen as a "2002 Arkansas Select Plant".
Rhapsody in Pink has a distinctly unique landscape appearance with soft pink flowers against nearly purple foliage.
They are deciduous plants and can be grown as large shrubs or gently pruned into multi-stemmed tree-form plants. The crape myrtle has become a mainstay in mild-climate landscapes because of its ease of production and cultivation, long-lasting mid-summer bloom, range of plant habits from miniature potted plant to large tree, and diversity of landscape uses.
Tight on space, but love to grow vegetable crops? Try growing vining crops on trellises: The plants are more exposed to sunlight and air, so they are less troubled by mildew and other diseases. And since most of the fruits dangle off the ground, they are less susceptible to rotting.
Many melons can thrive on a trellis. But because they're heavy, you'll need to support them with cotton or nylon slings
Visit our Heirloom Vegetable garden to see this great space-saving trellis idea in action as well as other handy practices such as raised beds and container crops. We use cattle panels that we curve from one raised bed to another for our trellises.
Pink Zazzle Gomphrena has large, hot pink to fuscia blooms.
The 3” wide flowers last several weeks in the garden or as a cut flower. It blooms constantly from spring to late fall, and performs best in warm weather and with high light.
Come see Pink Zazzle Gomphrena in our Greenhouse.
This Southeast Asia and Australia native plant is a sight to see. It forms pitchers (or Monkey cups) that hang from trees.
Starting with a normal looking leaf, the leaf develops a tendril at its tip which later curves upward to make a pitcher. At maturity, the pitcher inflates with air, fills with liquid, then opens to entice prey.
You can find this unusual plant in our Greenhouse.
The 10' tall shrub is not actually a rose but is in the Mallow Family and is sometimes called "Shrub Althea". Carl Linnaeus classified Hibiscus syriacus in the 18th century based on a herbarium specimen from Syria to which the species apparently had been imported long ago, since its origins are from India and East Asia.
Rose of Sharon comes in many colors - especially white, lilac, and pink. It occurs as a single flower, or as a hybridized double. Blooms first occur in late spring and continue through early fall, making Rose of Sharon one of the few summer-blooming shrubs.
Individual blossoms open in early morning, close at night, and usually last less than three days. Regardless of the flower's color, there is almost always an intensely maroon central spot formed by a concentration of pigment at the bases of five large petals. The almost-triangular serrated leaf of Rose of Sharon is semi-glossy dark green and about 3" long. The foliage is also deciduous. Rose of Sharon goes into a very long resting period and is one of the last shrubs to green up in spring.
Rose of Sharon is a great plant that can be pruned to show off its multi-trunks. We have several examples in our garden. Treeing it up enables the eye to see through the branches to any hardscaping or plants behind it to give the view a layering look.
This particular plant is in our Boulder Garden
Water Lily plants will add intense color and green foliage to any water garden, while also attracting birds and butterflies. These red, pink or white lilies will thrive with any other water plants already growing in your pond, and they are cold hardy.
We found them blooming in our water garden and had to share their beauty.
One look at this plant and you will guess its common name - Shamrock. Zinfandel Oxalis has dark plum-colored shamrocks the size of your palm with clusters of blush pink, lily-shaped flowers.
This old-fashioned shamrock houseplant is now high fashion, with its elegant foliage, abundant delicate flowers, and vigor. Only 6 to 10 inches high with a spread to 12 inches, this plant’s tiny leaf clusters and bright flowers are massed on trailing stems that spill over the sides of shaded window boxes and containers. Though this shamrock is frost tender, it is easy to overwinter indoors, and is a nice houseplant.
You can find this plant at the sides of the steps in the Boulder Garden.
