Flores forward to spring exhibition

few weeks before the start of spring flowers appear first year, including some that are indifferent to late fall, or even come to bloom 2 times (fall and late winter), as may occur with mandrake, as mentioned in other occasions in the blog, or our lively orchard daffodils (Narcissus tazetta ). These are often species that need to accumulate a certain number of chilling hours to bloom, or in your case to fruition, years of cold winters are annoying but we are the best crops causing most of Rosaceae (pear, apple, plum, cherry, almond, quince, etc..), which also begin to lay flowers or are about to do so.

Among the easiest flowers all our flora are the River Ash (Fraxinus angustifolia ), who as you see in the picture you just have a couple of yarns about carpel, without noticeable to the naked eye petals or sepals. © E. Laguna, 02.03.2011

However, some plants that bloom at this time go unnoticed, perhaps to be unattractive or because they live in places rarely visited. Among them we must include many of the trees with deciduous riparian as elms, poplars, willows, poplars or ash trees. These species may take much wind to disperse their pollen to make their fruits or seeds travel to distant sites, based on this idea, it is clear that interests them bloom before issuing the new leaves, and so the pollen will find few obstacles to travel from one flower to another, or to reach the female flowers in those species which are separate from the male or installed on different feet.

The early flowering strategy is complemented by a rapid fruiting, so that in a few weeks off, often adapted to the transport by wind or water can move quickly. The trees above do not therefore take several months to produce fruit, as they return most of the trees that populate our fields and woods (oak, strawberry, etc.).
