Euphorbia tirucalli

Euphorbia tirucalli, also known as the pencil tree, is a succulent shrub native to semi-arid and tropical parts of Africa.  With its densely packed whorls of dark-green, tubular branches, the pencil tree provides an element of pristine vitality to any home or garden.  Short-lived, oval-shaped leaves grow from the tips of the pencil tree branches.  In a similar fashion to the leaves, petite yellow flower clusters bloom on the ends of the branches during spring and summer.  The clusters of small green branches will be present at all stages of the pencil tree's life, but the lower branches will become thicker and brown as it reaches maturity.  Keep this plant away from children and pets, as the pencil tree produces a poisonous latex sap.  Wear protective eye gear and gloves to avoid exposure to the toxic sap while pruning or propagating.

For plant parents who travel often, the pencil tree is a great choice as it is very low-maintenance and neglect-resistant.  A healthy pencil tree requires dry, sandy, low-nutrient soil.  A great way to maintain favorable soil conditions is to utilize an unglazed clay pot, as these allow excess moisture to evaporate through their walls.  Whether you choose a clay pot or not, the pencil tree's vessel must have drainage holes to prevent root rot.  Being a semi-arid tropical plant, the pencil tree thrives in generous sunlight, temperatures warmer than 65℉ / 18℃, and low humidity.  This succulent is highly drought-resistant but susceptible to root rot, so allow the soil to completely dry out between waterings.  The pencil tree will not need to be watered more than three times a month, and only once or twice during the winter months.  Fertilize no more than once per year during the springtime to promote optimal growth.
