Flowers grow less yellow without sulphur, and that could affect the pollinators that need to see them
Both Van Gogh and Nature like to use sulphur-derived pigments for flowers, but what happens when there's not enough sulphur?

The colour of background vegetation reveals how bees see flowers
Studying how bees perceive flowers gives insight into how pollinators have influenced flower evolution.

Thermal Ecology to become a hot topic
We might think of flowers in terms of their colour and scent, but what about their temperature? A new review in Annals of Botany looks at the thermal ecology of flowers. In the paper Casper van der Kooi and colleagues...
Functional significance and optical properties of floral visual signals
Many plants produce colourful flowers that play a role in pollinator attraction. These floral visual signals may have distinct optical properties that differ in biological relevance. In this review, van der Kooi et al...

Association between community assemblage of flower colours and pollinator fauna
Flower colour plays a major role in the attraction and decision-making of pollinators. Different functional groups of pollinators tend to prefer different flower colours, and therefore may lead to different flower...
How to make a red flower: the combinatorial effect of pigments
Red flowers have evolved repeatedly across angiosperms and are frequently examined in an ecological context. However, less is known about the biochemical basis of red colouration in different taxa. In a recent study...

Selection and evolution of flower colour
We currently know little about the evolution of flower colour when multiple pigment families are present. Ellis and Field examined the patterns of evolutionary transitions between anthocyanin-pigmented (red, pink, blue...

Long-tongued hawkmoths form a pollination niche
The study highlights the value of a niche perspective for understanding the geographical context and functional significance of floral traits.
Why do petals have conical epidermal cells? (Review)
The conical epidermal cells found on the petals of most Angiosperm species are so widespread that they have been used as markers of petal identity, but their function has only been analysed in recent years. Whitney et...
