Landscape Attributes

Rift Blue Lobelia is an herbaceous annual with a mounded form. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

Rift Blue Lobelia is recommended for the following landscape applications;

• Mass Planting
• Rock/Alpine Gardens

• General Garden Use
• Groundcover
• Hanging Baskets

Planting & Growing

Rift Blue Lobelia will grow to be about 8 inches tall at maturity extending to 12 inches tall with the flowers, with a spread of 8 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. Its foliage tends to remain low and dense right to the ground. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. This plant should not require much in the way of fertilizing once established, although it may appreciate a shot of general-purpose fertilizer from time to time early in the growing season. It is not particular as to soil type or pH. 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.

Rift Blue Lobelia is a fine choice for the garden, but it is also a good selection for planting in 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.
