Philadelphus in Maryland...

Mock Orange, Philadelphus x virginalis in full bloom. This is an excellent plant for hedges, along fences, lining a driveway, etc. The 2 inch flowers appear in May, are lightly fragrant a last about 2 to 3 weeks. Its a North American native, prefers average to moist conditions, and shouldn't be allowed to dry out. Make sure it gets supplemental water on the hottest summer days. It is not particular to soil type or pH. This was planted in mostly clay and performs well. It blooms on the previous years growth so prune immediately after blooming if needed. As for sun, this plant gets about 4 - 5 hours a day (morning to noon) and still does very well. 

This is Mock Orange Philadelphus x lemoinei. This cultivar grows to about 4 feet and the flowers are a little smaller than virginalis above. We've had this one for three years and it finally bloomed this season. It is planted in a clay compost mix and only gets about 2 hours of afternoon sun. We expect it to bloom heavily next season because it has a lot of new growth.

A pair of Proteus clematis blooms. This variety is odd because it can have both single and double flowers on the same plant. Both of these are doubles.

This was the only patch of Baptisia australis or False Indigo that survived a direct hit by voles and bloomed.

Another casualty of voles this spring was the variegated Weigela. As the flowers age they turn from white to pink.

Variegated Fleece Flower or Fallopia japonica 'Variegata' has colorful foliage and small poofy flowers in the summer. We grow it for the foliage and red stems. As you see it stands out against the green. It prefers moist soil, mostly shade but can take some morning sun. It will burn in afternoon sun.
