Planting & Growing
Blue Palace Lobelia will grow to be only 4 inches tall at maturity, with a spread of 6 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 6 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 should be grown in a location with partial shade or which is shaded from the hot afternoon sun. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. 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.
Blue Palace Lobelia is a fine choice for the garden, but it is also a good selection for planting in hanging baskets. Because of its trailing habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
