Lavandula angustifolia LAVENDER Valuable herb used as edging or foreground border plant, growing best in light loamy soil with excellent drainage. Demands average moisture. Pleasantly fragrant foliage, whitish gray-green and semi-evergreen, creates a fine foil for other flowers. Clip back this woody plant in spring to maintain a rounded form. Leaves are oblong and linear. The flowers are used in potpourri.

Leptodermis oblonga LETPTODERMIS First collected in 1905 by Ernest Wilson, this compact member of the Rubiaceae (Coffea arabica) family has only recently been gaining popularity in cultivation. Although slow to break winter dormancy, once this little shrub starts flowering in late spring it doesn’t stop until frost, offering a full season of bloom. Their sweetly fragrant, tubular, lavender flowers seem to be a favorite of the hummingbird moth. I have witnesses up to four at a time hovering over one plant, vying for the nectar filled flowers. Leptodermis is dense and compact in habit making it suitable for the sunny perennial border. Found in Northern China and the Himalayans. Tolerant of most substrates but resents heavy or wet soil.

Lespedeza thunbergii BUSH CLOVER Spectacular when in bloom, this semi-shrubby plant with pea-like foliage, developes into an arching mass of wiry stems in summer. Great when grown on a bank or wall allowing the heavily laden flowering stems to wave out and become more visible. Flowers occur on new wood. Cut back to the ground in early spring prior to new growth. Can reseed, and sometimes root at stem nodes which lie on the ground. Average soil, good drainage.

Leucanthemum [Superbum Group] (Chrysanthemum superbum, C. maximum) SHASTA DAISY is a sound perennial in most moist soils, but prefers rich moist soils. Vigorous, bushy clumps of sturdy stems carry dark green, smooth, toothed and lance shaped leaves, and produce a long display of showy blooms. Dead-head to extend blooming season. Leucanthemum vulgare (Chrysanthemum leucanthemum) OXEYE DAISY also grows well in rich, moist soil. Flowers one month earlier than shasta daisies. Spreads rapidly by the root and self-sown seed. Leaves are deep green, spoon shaped and toothed. These bright daisies are excellent for daisy pickers.

Ligularia stenocephala 'The Rocket' LEOPARD PLANT A large plant with showy flowers soaring above the foliage. Used as a border specimen or planted in groups, they prefer a cool and very moist to wet site, even bog gardens. Finely toothed, leathery, heart shaped leaves. Loves deep, rich, moist, soil but will settle in ordinary garden soil when kept moist. If hot, better be in partial shade. L. dentata 'Othello', BIGLEAF LIGULARIA has 12 in. kidney shaped leaves with purple in them, with a fleshier texture in contrast to the finer, toothed texture and shape of L.'The Rocket' and L. przewalskii. L. przewalskii has more triangular shaped leaves than 'The Rocket'. All three prefer conditions described above.

Lilium HYBRID LILY Well known and irresistible are lilies for gardens and bouquets. Require very well drained moist and fertile soil, deep and well mixed with humus and a fertilizer rich in potash and phosphate (low nitrogen). Lilies provide a floriferous spectrum of color within and above green, narrow and lance shaped foliage. Most important is the good drainage, especially for winter, and steady moisture for summer.

Liriope LILY TURF Ideal general ground cover, or edging plant, adaptable to any well drained soil, though moist and fertile is better. Prefers a light and porous soil. The evergreen foliage is sensitive to sunscald in winter and summer sunburn, so it is best to plant in partial shade. These grass like plants introduce dark greens, green to yellow green, and variegations of foliage to your garden. Cut back a bit in early spring before new growth. Liriopes actually clean the air of pollutants. Little flower clusters on stalks later bear black ornamental berries. L. muscari is valuable as a slow grower or in clumps, L. spicata as a more rapid colonizer with thinner blades.

Lobelia siphilitica GREAT BLUE LOBELIA Will prosper and self-sow in moderately fertile moist garden soil with organic matter added. Treasured late season for its long lasting display. The green leaf is narrow at both ends and attached to the flower stem. L. cardinalis CARDINAL FLOWER has brilliant red spikes in summer. Best in moist, shady locations that retain moisture during dry periods. Hummingbirds seem drawn particularly to that red color of L. cardinalis. For lobelias, the brighter the light of the planting site, the more moisture will be required to obtain optimum results.
