As a horticulture and landscaping expert , I have had the delight of work on with a wide variety of flora , include geraniums . When it come to geranium , there are numerous coinage and cultivar to choose from , each with its own unique qualities and characteristics . However , if we are talking about the rarest geranium , then Geranium arboreum certainly takes the spot .

Geranium arboreum , also known as the tree geranium , is a unfeignedly remarkable and rare coinage . What make it so special is the fact that it is the only bird - pollinate geranium in the world . This unique version place it aside from all other geraniums and lay down it a true stone for any avid nurseryman or plant enthusiast .

The rarity of Geranium arboreum can be assign to several factor . first off , its natural habitat is quite limited . This species is aboriginal to the Canary Islands , specifically the island of Tenerife . Its distribution is restrict to certain area of the island , make it relatively difficult to come across in the wild .

Additionally , Geranium arboreum has specific pollination requirements that further contribute to its rarity . Unlike most geranium , which are typically pollinated by insects , Geranium arboreum bank on birds for pollination . This specialization in pollenation has likely germinate as a result of the scarceness of insect pollinators in its aboriginal home ground . The unique kinship between this geranium species and its avian pollinators total to its temptingness and rareness .

In terms of coming into court , Geranium arboreum is a striking industrial plant . It typically grows as a bush or small Sir Herbert Beerbohm Tree , reach heights of up to six feet . The leaves are deeply lobate and have a shiny , sinister immature color . When in bloom , the plant produces cluster of vibrant crimson flowers , which serve as beacon light to attract its bird pollinators .

I vividly remember the first time I came across Geranium arboreum during my botanical explorations in Tenerife . It was a truly awe - inspiring deal to see these beautiful plant standing magniloquent amidst the broken volcanic terrain . The vibrant red flower stood out against the background of the island ’s dramatic landscape , make a mesmerizing video display of nature ’s beauty .

Due to its rarity and unequaled pollination chemical mechanism , Geranium arboreum is highly seek after by collectors and gardening enthusiasts . However , its cultivation can be challenging , as it requires specific growing conditions to thrive . This species prefers well - drained ground , ample sunlight , and moderate lacrimation . It is better suited for Mediterranean or semitropical climates , making it a prized summation to garden in these regions .

Geranium arboreum is undeniably the rarest geranium species . Its limited statistical distribution , bird pollenation , and stunning coming into court make it a true botanical treasure . Whether run into in the wild or cultivate in a garden , Geranium arboreum never fails to captivate with its singularity and looker .
