'Sombrero' Sneezeweed is another lovely compact Helenium from Arie Blom's Mariachi™ series. Blooming profusely in mid to late summer, 'Sombrero' is topped with bright yellow daisy-like flowers with darker yellow domed centers. The upright compact habit and prolonged bloom period make Helenium 'Sombrero' an excellent choice for mixed sun containers. It is also a great pollinator attractant in mixed perennial borders.
