Tree Indiana Native Crataegus phaenopyrum [Washington Hawthorn] One of the finest small trees for winter color. The 1-3" thorns can be dangerous, especially around children. Fireblight, leaf spot, and cedar-hawthorn rust are among the worst problems, although more trouble-free than many hawthorns. Japanese beetles like to feed on hawthorns.
Tree Indiana Native Crataegus viridis [Green Hawthorn] An attractive small tree with beautiful white flower corymbs and bright red persistent fruits. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Tree Crataegus viridis 'Winter King' [Winter King Green Hawthorn] An attractive, nearly thornless vase-shaped small tree with beautiful white flower corymbs and large, bright red persistent fruits. This cultivar was discovered in a fence row by Bob Simpson in Vincennes, Indiana. Very adaptable, although leaves are often badly infected by rust so that the entire plant appears to be suffering from the measles.
Shrub Cycas revoluta [Sago Palm] Unlike what the common name suggests, the Sago Palm is not a true palm, but actually a cycad. Useful for fine planting near entranceway. Not salt tolerant. Scale, leaf spot, micronutrient deficiencies can be problems. The variety variegata has yellow-green leaf variegation patterns.
Shrub Daphne × burkwoodii 'Carol Mackie' [Variegated Burkwood Daphne] Requires excellent drainage, relatively low fertility, and consistent moisture. Best in a cool site, on soil with pH near neutral, in partial shade to full sun. Notably difficult to transplant. Sometimes dies suddenly with no warning signs. 'Carol Mackie' is more vigorous than the species type.
Shrub Indiana Native Dasiphora fruticosa [Bush Cinquefoil] Extreme hardiness and long season of bloom make this a favorite in severe climates. Low stature and tolerance of poor, dry soils give it added usefulness in other areas also. Can develop a ragged, unkept habit over time. Remove 1/3 of canes each year (3-year pruning cycle), and consider renewal pruning to a very low framework every 3-5 years if needed.
Shrub Dasiphora fruticosa 'Abbotswood' [White Bush Cinquefoil] 'Abbotswood' has beautiful, large, white flowers and an especially long blooming period. Extreme hardiness and long season of bloom make Potentilla fruticosa a favorite in severe climates. Low stature and tolerance of poor, dry soils give it added usefulness in other areas also. Can develop a ragged, unkept habit over time. Remove 1/3 of canes each year (3-year pruning cycle), and consider renewal pruning to a very low framework every 3-5 years if needed.
Shrub Dasiphora fruticosa 'Yellow Bird' [Yellow Bird Bush Cinquefoil] 'Yellow Bird' has large, single to semi-double yellow flowers. Extreme hardiness and long season of bloom make Potentilla fruitcosa a favorite in severe climates. Low stature and tolerance of poor, dry soils give it added usefulness in other areas also. Can develop a ragged, unkept habit over time. Remove 1/3 of canes each year (3-year pruning cycle), and consider renewal pruning to a very low framework every 3-5 years if needed.
Shrub Deutzia gracilis [Slender Deutzia] Nice in flower as they can cover the plant, hardiest of all deutzias, and relatively pest free. Once flower show is over, plants can look bedraggled. Branches often killed by cold temperatures in Northern range (or just die back), and then it's often best to cut it back to 6". Renewal pruning every few years can maintain vigor and form. Prune to maintain form by removing old stems, and do so after flowering to encourage…
Shrub Deutzia gracilis 'Nikko' [Dwarf Slender Deutzia] 'Nikko' is a compact, dense, and rounded shrub. Nice in flower as they can cover the plant, and relatively pest free. Branches often killed by cold temperatures in Northern range (or just die back), and then it's often best to cut it back to 6". Renewal pruning every few years can maintain vigor and form. Prune to maintain form by removing old stems, and do so after flowering to encourage best flower show the following…
