Planting & Growing
Giant Cactus Yellow Zinnia will grow to be about 30 inches tall at maturity, with a spread of 15 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. This fast-growing annual will normally live for one full growing season, needing replacement the following year.
This plant should only be grown in full sunlight. 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 highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid.
Giant Cactus Yellow Zinnia is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
