Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to alkaline (less than 6.8 to more than 7.7) soil.

 Leaf Color    Green

 Culture Notes
Most Clematis are hybridized and do not come true from seed.  Stem cuttings can be taken early summer.  Removing spent flowers often increases the blooming period.  Plant so that roots are shaded.

Since Clematis do not climb by tendrils or aerial roots, their leaf petioles will twine around anything close by (including themselves) for support.  Clematis are beautiful specimens climbing up (with proper support wires, etc.) a fence, trellis, lamp post or wall.  It's best not to plant Clematis in an area where it would have to fight for its water supply, such as next to the roots of a tree.  'Serenata' has beautiful 5-6" purple blossoms with a dark purple bar and yellow stamens.

When using a trellis, add compost or cow manure in the spring to the base of this plant.  Also use a water soluble fertilizer (15-30-15) every two weeks through May, June and July.

Leaf Color    Green
Fall Color    No change in fall color
This plant has attractive foliage.

Culture Notes
Attractive, violet-blue flowers give this plant its charm. Lilyturf is a 6- to 12-inch-tall herbaceous perennial that is useful in the landscape as a ground cover and accent plant.  This plant spreads slowly by rhizomes and forms thick tubers that look like small potatoes.  The 8- to 20-inch-long, grass-like leaves arise from a central crown.  The small, purple flowers of Lilyturf occur in terminal racemes that sit atop an 8-to 10-inch tall, violet-brown scape.  These flowers appear in the summer and are followed by blue-black berrylike fruits.  Flowers are mostly inconspicuous due to the brightly colored foliage. This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Lilyturf is a great plant for bordering a sidewalk or as an edging for a landscape bed.  It will grow well underneath trees or around shrubs.  However, it will not tolerate foot traffic. Liriope will grow in a sunny location, but prefers one that has partial shade or full shade.  It prefers well-drained soils and is moderately tolerant of drought and salt spray.  This plant does have a negative reaction to high temperatures and can melt out in warm weather.

These plants can be easily divided in the spring.  Cultivars will not come true from seed.  Monarda should be planted in areas with good air circulation in the full sun.  Attracts pollinators.  In the spring, remove dead foliage only. In the fall, cut back to 6", and deadhead spent flowers after blooming is done.  The blossoms and foliage of this fragrant plant can be used either fresh or dried in salads, wines and fruit drinks.  Other possible uses include pot pourris and, as a purported calming element, Bergamot tea or milk.

This plant is often infected with mildew after flowering.  If so, cut down to new foliage.
