| General Description | Large palmate leaf, with brown hairs on the upper surface of the leaf axil.
Does not produce fruit since the double flowers are sterile. Broadly pyramidal-rounded form with branches ascending to the ground. Spectacular in bloom. |
| ID Characteristic | A double flowering form of A.hippocastanum that produces sterile flowers and hence no seed litter. |
| Shape | Large, pyramidal to rounded crown |
| Propagation | Grafted on A. hippocastanum rootstock. |
| Cultivation | Tolerant of a wide variety of conditions but likes adequate moisture in our summer droughts. Does not like waterlogged soil. |
| Pests | Extensive leaf blotch (Guignardia aesculi) but does little damage to the tree since it occurs late in the season and hence does not warrant control. Symptoms are irregular brown blotches with light yellow borders, with severe infections causing premature leaf drop. Remove and dispose of all fallen leaves in the autumn, do not compost. Prone to horse chestnut leaf miner ( Cameraria ohridella). |
