Eucalyptus macrocarpa (Mottlecah)
Today I potted on a potful of seedling Eucalyptus macrocarpa. I just read that they are slightly frost tender. Not sure what to make of that. They certainly seem not to be bothered by temperatures down to -4C. I have had the pot of small seedlings sitting out in the frost this winter. They had their second set of leaves which is why I had to get them into their own pots. The roots were well developed.
This is a rather straggly, shrubby Eucalypt. At the arboretum they are about 3m tall by 4m wide. It appears they can get to 5m tall. There is no sign that they will ever be that tall here. The largest I have seen in our high pH soil is 2m. There are apparently some compact forms around but I think this size is due to the soil. The flowers are about 8cm in diameter and the fruits are very decorative. The nectar feeding birds love this plant. I have used the dried fruit at Christmas time with a candle wedged into the open valves.
The shrubs need to be regularly pruned. The plants grow best in dry areas. They need good drainage and warmth to do well.
I think they would make a great container plant. Apparently in USA they are used as an indoor container plant.
