Celosias are frequently overlooked for showier summer annuals, and that's a shame. Intenz Classic Celosia provides stunning magenta color on texturally interesting plumes that continue blooming from late spring into the fall. Growing 18 to 24 inches tall, this celosia has a narrow profile, making it a good choice as a thriller or filler in container planters and hanging baskets. Tolerant of the sun and heat, Intenz Celosia looks its best when watered regularly and fertilized at least every other week.
