Shrub Philadelphus coronarius [Sweet Mockorange] Well adapted to different light (even shade) and soil conditions, especially to dry situations. Relatively trouble-free, and one of the most fragrant of the mockoranges. None of the mockoranges have much landscape interest after the season of bloom. Becomes leggy if not pruned. Pruning should be done after flowering (flower buds form on previous years wood), and to maintain fullness of form.
Shrub Philadelphus inodorus [Scentless Mock Orange] This shrub only has interent when it is flowering; even then, this specific speciman is not as great as it is not fragrant, unlike its relative, P. coronarius.
Shrub Philadelphus lewisii 'Blizzard' [Blizzard Mock Orange] 'Blizzard' is a cultivar that is more cold hardy than the straight species. It is known for its white flowers that are very fragrant.
