""'Penicillium jugoslavicum " "'is an anamorph species of the genus of " Penicillium " which was isolated from seeds of Helianthus annuus L.

Molecular phylogenetic data place the genus as sister to " Sclerocarpus " and in a relatively basal position in the subtribe Helianthinae, the group that includes the common sunflower ( " Helianthus annuus " ).

Allelopathy is a defense mechanism, least pronounced in domesticated forms of the common sunflower, Helianthus annuus, and very strong in the seed hulls of H . Maximiliani, a multibranched, bright yellow 8 to 10 footer that is one of the easiest perennial species to find.

"Lagascea " is a member of the same subtribe Helianthinae as the common sunflower, " Helianthus annuus ", but it looks different because it has heads that are reduced to have 1 ( or 2 ) flowers, and are clustered into compound units that mimic heads and are sometimes called syncephalia.

Although at one time, " Simsia " was considered to be related to other genera with flattened cypselae, such as " Encelia ", it is now firmly established that " Simsia " is part of subtribe Helianthinae ( the taxonomic group which includes the common sunflower, " Helianthus annuus " ), and is a close relative of " Tithonia"

Many members of Asteraceae are copious nectar producers and are useful for evaluating pollinator populations during their bloom . " Centaurea " ( knapweed ), " Helianthus annuus " ( domestic sunflower ), and some species of " Solidago " ( goldenrod ) are major " honey plants " for beekeepers . " Solidago " produces relatively high protein pollen, which helps honey bees over winter.
