Gardeners' Notes:

I love this plant especially since my garden is so small, the color makes the walk-way perk up.
I am having a problem with the leaves truning brown (rust colored) and then falling off--to the extent It now only has leaves and flowers at the very tip of the plant.
No new signs of leaves appearing.
I would like some feed-back about what is happening to the plant.
Thank you

This is a shrub or small tree that is pretty common in the central brazilian plateau, mainly because its a very, very atractive plant when blooming.

And when it blooms, it meas it. It gets entirely covered with pink to purple flowers, which makes it visible from long distances in the middle of other plants.

It is a frost tolerating plant, but still needs full sun and high temperatures often. It likes acidic, deep and well drained soils, and constant watering during the summer, fading it away until the winter, when it needs barely no water. The hydric stress will force it to produce flowers in abundance.
