Description

Helianthus argophyllus

Certified Organic

Fantastic and dramatic flowers with highly contrasting silver foliage and golden blooms.

This stunning plant is native to the Texas Gulf Coast, which is better known for its petroleum than its silver and gold. But these blooms are worth their weight in any mineral resource: profuse golden flowers jut above a sea of silvery gray-green leaves on multi-faceted branches that spread far from the stem. The contrast between the blooms and the leaves is spectacular; it is hard to believe one plant can pair such striking tones together in such abundance. They are, as the artwork highlights, truly celestial.

About the Artist
Artwork by Lachlan Herrick. Lachlan combined oil painting and digital illustration techniques to achieve the sublime beauty of this sunflower portrait. The depiction incorporates several armadillos against a subtropical sky, both of which nod to this plant's Gulf Coast origins.
