Prionotes cerinthoides (Climbing Heath) is one of the glories of the rainforest of south west and west Tasmania where it grows up the trunks of trees, often to heights of over 10 metres and in early autumn is covered with waxy crimson bells 20-25mm long. After only limited success growing it in the open garden, I decided to try it as a container plant. I hollowed out a length of tree fern trunk and filled it with a mixture of rotted wood, peat moss, loam and coarse sand and planted a young specimen in the mixture. It was kept in the glasshouse with the intention of putting it outside when well established. However, it thrived and within a short time shoots were growing at the top of the container and were penetrating through the sides, so I left it in the glasshouse. It flowered in the first autumn after planting and has continued to grow well. Four years after planting it was growing out through the base of the tree fern. The glasshouse has off-peak heating during the colder months of the year so that the night temperatures do not fall below about 8 degrees C. In summer it is protected with shade cloth. The plant is now 12 years old and continues to flower abundantly in most seasons. Ensuring the container is kept moist is essential. |
