Ideal to integrate into shrub or mixed borders for solid, long-season color without additional care. Makes a fine addition to south and west facing foundation beds. Use in the back of perennial borders to intensify season long color. Plant in irregular groupings for a large scale cover that blocks weeds. Great in pairs to flank an entry, steps or gate. Plant en masse to create a low, semi-formal hedge or to clean up unattractive paving edges around porches and patios. Thrives in enriched, loamy, well-drained soil. Water deeply, regularly in first growing season to establish root system; avoid overhead watering. Feed before new growth begins in spring; repeat mid-season. Mulch to keep roots cool. Prune in early spring after threat of frost is gone to promote vigorous new growth. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. NOTE: Some flowers and plants may be harmful or poisonous to people or pets if touched or ingested. If you require more information before placing an order, please let us know in advance. |
