Blew My Mind Evolvulus

'Blew My Mind' Evolvulus

Another plant to add a touch of blue to your garden.

Blew My Mind Evolvulus is a dwarf morning glory evolvulus hybrid from Proven Winners.

Blew My Mind Evolvulus will blow your mind when you see how well it performs in the heat of the summer. Blew My Mind loves the sun and hot weather so be sure to protect it from light frosts that might happen in the late spring or early fall so that this evolvulus can keep showing off.

The electric blue flowers will almost glow in the sunlight and will make an impressive display in containers or in the landscape. The silvery-green leaves help the bloom color pop. Blue My Mind is a trailing and semi-mounding plant. It can look particularly stunning when combined with other colors such as lime green, light yellow, and white, either in the garden or in containers.

You can see Blew My Mind in the shade of the Entry Walk (under the Acoma crape myrtle closest to the Linnaeus stature) and in the sun of the Boulder Garden along the pond walk (2016)

Acoma Crape Myrtle

Acoma Crape Myrtle

Tulsa's summer heat is a natural for growing crape myrtles, and their showy flowers really make any landscape in the dead of summer jump out with wonderful color. The semi-dwarf, slightly weeping growth habit of an Acoma give it an especially graceful appearance.

Along with its modest size (9 feet tall and 11 feet wide) and clusters of pure white flowers, this crape myrtle can brighten any special spot in a landscape. It provides abundant summer color with a minimum of maintenance, withstands droughts after becoming established, and is relatively free of disease and insect difficulties. Because of these features, crape myrtles should be used more often in the home landscape.

Acoma crape myrtle really liven up the Entry Walk of the Linnaeus Garden.(2016)

Althea Fireworks

Althea Fireworks

How about a multi-color Rose of Sharon for your garden?

This woody shrub is excellent for late summer garden color. Plants can get to around 12' tall by 10' wide and grow in somewhat of a vase shape. Flowers are white, red, purple, pink or violet or a combination and either single or double.

Also known as Hibiscus Syriacus Tri Color, this plant starts to flower in June and continues through September. It grows well in about any soil and has done nicely in our garden during both rains and hot weather.

You can control the size of this plant with heavy pruning in the early spring each year which also helps to produce larger flowers in summer.

Althea Fireworks

You will find Althea Fireworks in our Fountain Garden and in the Entry Garden by the sidewalk along the driveway (2016).



Would you like some color in your garden? It's easy with Garvinea...Garvinea is a revolutionary new gerbera with a unique combination of features. Using genetics from wild South African plants, breeders have managed to come up with a color palette of strong, prolific, free flowering gerberas which have cold tolerance and superior pest and disease resistance.

Garvinea are happy in full sun to part shade and look gorgeous mass planted in garden beds and large containers. What Garvinea lacks in flower size compared to other gerberas is more than made up for by the quantity of flowers, with each plant yielding well over 70 blooms per year. They provide continuous color from spring right through summer to the end of autumn. Garvinea are winter hardy and survive where temperatures may drop to -5°C. Come spring the flowers will start popping up for another long season. Being pest and disease tolerant means that Garvinea are much easier to grow than most other gerberas.

You can find Garvinea on the sunny side of the Entry Garden above the driveway test beds.(2016)

Osteospermum White Lightning and Blue-Eyed Beauty

 Osteospermum White Lightning

Osteospermum White Lightning - in November after first frost

Grow White Lightning in any climate.

Cheery crisp white daisy blooms with a yellow center are striking even “asleep,”. Its yellow undersides makes it appealing even when the flower is closed on cloudy days. And it presents well when the flowers partially close and both colors are visible.

Osteospermum White Lightning also looked great in the Linnaeus Garden well into the fall. After our first frost in early November, it looked as crisp and cheerful as it did in summer.

Osteospermum Blue Eyed Beauty

Osteospermum Blue-Eyed Beauty, yellow with blue eyes

These prolific plants produce stunning flowers all summer long.

The Osteospermum Blue-Eyed Beauty is a one-of-a-kind African daisy with stunning blue eyes, that also continues blooming from early spring through autumn. These prolific plants mound 12"-14” and produce armfuls of really pretty cut flowers that will be the talk around your dinner table; meanwhile, back in the garden, these plants are star performers in both sun and shade.

You can find these fresh daisy-like flowers above our test beds along the curved drive outside the fence.(2016)


Lantana Bandito Rose

Lantana Bandito Rose

Lantana - Little Lucky Lemon Cream

Little Lucky Lemon Cream

Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. In our Tulsa zone they are usually considered annuals because of our colder weather in the winter. If we have a mild winter this plant can come back in the spring.

Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. If you have a hot, baked spot, lantana is your answer. This hardworking plant not only thrives with little moisture and in full, unyielding sun, it does so with ease.

In fact, lantana is a flower that seems to have it all: it produces an abundance of brightly colored flowers all summer and fall; it's a magnet for butterflies and hummingbirds; it's easy to grow and a great choice for containers.

Lucky Lemon Cream and Bandito Rose Lantana are newly introduced varieties. They bloom up to three weeks earlier than other compact lantanas. They bloom from spring through fall and grow in a mounded compact shape.

Specimens are located in beds outside the gates along the curved drive below the Entry Garden. The butterflies have been abundant.(2016)

Cotton and Sorghum

Red Cotton

Naturally-colored red cotton growing in a container.

Have you thought about using vegetable plants as a decorative planting on your patio that would be a great conversation starter? Cotton and Sorghum would meet that criteria.

These two plants normally have two totally different purposes; in addition to being crop plants, they are also used by farmers as rotation plants to increase the yield for each plant.

The cotton plant is generally a shrubby plant having broad three-lobed leaves and seeds in capsules or bolls; each seed is surrounded with downy fiber, white or creamy in color and easily spun. Imagine explaining to your children or grandchildren how their t-shirts are made from this plant.

New for 2016: We have a naturally-colored cotton plant growing in a container in our Vegetable Garden - Red Cotton!

Naturally-colored cotton is cotton that has been bred to have colors other than the yellowish off-white typical of modern commercial cotton fibers. Colors grown include red, green and several shades of brown. When the boles actually open, the cotton tends to be a rather washed out shade of one of the colors. The cotton's natural color does not fade. Yields are typically lower and the fiber is shorter and weaker than the more commonly available "white" cotton.

This form of cotton may feel softer to the skin and has a pleasant smell. Naturally-colored cotton is still relatively rare because it requires specialized harvest techniques and facilities, making it more expensive to harvest than white cotton. By the 1990s most indigenous colored cotton landacres or cultivars grown in Africa, Asia and Central and South America were replaced by all-white, commercial varieties (source: Wikipedia).


Colorful sorghum growing
in a container.

The Sorghum plant is a genus of numerous species of grasses, some of which are raised for grain and many of which are used as fodder plants either cultivated or as part of a pasture. Researching these plants can give you a lot of material to use for great conversations along with providing you with a very different and interesting plant to watch as it matures.
