  • Description

  • Notes

Recommended for water conservation gardens, this fast-growing evergreen is capable of reaching heights of 80'. Its fragrant, fern-like leaves produce showy flowers during the months of May and June. This tree is multi-stemmed and grows well in groves and on rocky slopes. It needs well-drained soil. If planted along the coast, the tree will be free from trouble.
Planting: 1. Dig a hole 1" less the depth and 2 times the width of the container. 2. Fill hole with water, let soak. 3. Set root ball in hole. 4. Fill hole halfway with native soil and water. 5. Finish back filling hole, build basin and water.
