Texas Vervain (Verbena halei), Verbenaceae Family, Texas native, perennial, blooms March through August and then starts tapering off

Also known as slender verbena and Texas verbena, Texas vervain blooms from May to June. It is listed as a subshrub in the USDA Plant Database, but I am including it here. Texas vervain is a tall, spindly plant that usually 1.5 to 2 feet tall, but can grow to 3 feet tall. It has small, about 1/4" wide, light purple flowers that start forming along the stem gradually move up the lengthening stem as the plant grows.
