Philodendron burle-marxii

A climbing evergreen perennial vine growing up the trunks of trees in tropical forests of Colombia, Ecuador and Brazil. It produces glossy, elongated, heart-shaped, textured leaves to over 30cm long on mature plants. In cultivation it is a moderately fast grower, producing 30-60cm of new growth per year in ideal conditions. Plants can reach 1.2m high and across. It is reluctant to produce flowers in cultivation, but can produce flowers when mature and in ideal conditions, consisting of a sheath-like spathe, white on the inside, flushed red at the base, and green on the outside, which surrounds a white spadix or column. The foliage of the typical form is all green, while there is a variegated form in green and yellow

How to grow

Cultivation

Under glass, grow in an open, ericaceous, well-drained, but moisture-retentive mix, which can include, lava rock or pumice, fine fir bark and leafmould or chopped sphagnum moss, choosing a position in bright but diffused light. During the growing season, allow the surface of the compost to become just dry before thoroughly watering the compost. Avoid plants sitting in water which can cause the roots to rot. Apply a liquid houseplant fertiliser monthly during April to September. Water less frequently in winter, when growth slows right down, and stop feeding until the spring. Repot every 2-3 years. See Philodendron and houseplant cultivation for further advice
