Landscape Attributes

Lobelix Lilac Lobelia is an herbaceous annual with a mounded form. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This is a relatively low maintenance plant, and may require the occasional pruning to look its best. It is a good choice for attracting butterflies and hummingbirds to your yard. It has no significant negative characteristics.

Lobelix Lilac Lobelia is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Container Planting
  • Hanging Baskets

Planting & Growing

Lobelix Lilac Lobelia will grow to be about 8 inches tall at maturity, with a spread of 16 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant does best in full sun to partial shade. It is quite adaptable, prefering to grow in average to wet conditions, and will even tolerate some standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Lobelix Lilac Lobelia is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
