Sandy soils may heat up very quickly when the sun is out but, by the same logic, they also cool extremely quickly as soon as the sun sets. With nowhere to go but up, many species that couldn’t handle either the rate of climate change or the altitude adjustment simply winked out of existence. During the rainy season, alligators can be found floating in open water or sunning themselves on land. One layer of cells will immediately begin to expel water, causing them to contract. By opening itself up to a wider variety of fungal partners, the broad-leaved helleborine orchid is able to live in places where pickier orchids cannot. This likely reflects the fact that their ancestors found refuge in warmer, low-elevation habitats in southern Europe. The key to their success as vines lies in highly modified stems with an intriguing band of specialized cells that provide them with a physically sound anchoring mechanism.While working in the garden the other day, I noticed that some of the nodding onion (As always, I hit the literature. Though at first glance it doesn’t look like it, pineappleweed is a member of the daisy family (Asteraceae). The aesthetically pleasing, curly tendrils of your cucurbits serve a very important function in the growth of the plant. Listen to In Defense of Plants Podcast episodes free, on demand. Thus, the faster the plant can respond, the more likely that bees are willing to stick around and visit more flowers. Take a close look at the tendrils on a cucumber or squash vine and you will notice that each tendril curls in two different directions, separated by a kink or “perversion” (as it is known in the literature) in the middle. They knew that in drier climates, some ant species have evolved to produce considerably less antimicrobial fluids. Interestingly, this often results in more individuals being produced via clonal offshoots. Soils that have built up over time are lifted out of the hole and piled into mounds. Now, some have argued that the alcohols are not the product of the plant but rather the result of fermentation by yeasts and bacteria living within the nectar. The correct answer is the whole vine! As such, star chickweed probably doesn’t experience as much competition for light early in the season. Their lacy appearance is quite beautiful juxtaposed with the hand-like, sterile pinnules. However, its not just the elements that have selected for downward pointing flowers. It stands to reason that a plant that can modulate the quality of its nectar reward in response to pollinator availability could potentially increase its fitness. I can’t really fault myself for it because so many of my early plant experiences occurred east of the Mississippi. Few orchids are as generalist in their ecology as this species. At least one study in Europe was able to demonstrate that over 60 distinct groups of mycorrhizal fungi were able to partner with this orchid. At this point in time, these are some of the best pieces of evidence we have in explaining the disparity in tree diversity between Europe, North America, and Asia. When you consider how many hollow trees are on the landscape, you begin to realize just how much habitat these trees can provide.

Tawkin, host of the incredible Black in the Garden, a podcast that "resides at the intersection of Black Culture and horticulture."
Join my friends and I for a podcast celebrating everything botany.Plants are everything. It throws all of its energy into one, truly massive reproductive event. Because ants tend to live in high densities in close quarters, this antimicrobial fluid helps keep their little bodies clean of any pathogens that might threaten their existence. That is exactly what milky quartz does. All in all, gator holes are extremely important habitats. Some trees force their resident treehoppers to emerge and mate earlier than others and vice versa. Take a look at a list of tree species from temperate Europe, North America, and Asia and you will notice a glaring disparity. Through a complex series of experimental trials, scientists were also able to demonstrate that this behavior was the result of pollen limitation rather than nectar. With plenty of hungry ants always on the lookout for food, the smokebush has managed to tap in to an abundant and reliable vector for pollination.
To be accused of living under a rock is generally not a good thing in today’s society. The process of digging a gator hole may seem destructive but it all must be placed in the context of the surrounding environment.
It could be that the taller, more vigorous sterile shoots are better able to compete for light as the forest fills in around star chickweed.
