Information

Summer is here!

  • Lily-of-the-Nile (Agapanthus africanus) Evergreen perennial that is native to South Africa (not the Nile River as the misleading common name suggests). The flowers are clusters (umbels) of blue, funnel-shaped flowers atop stiff upright stalks.

  • Hummingbird Summersweet (Clethra alnifolia ‘Hummingbird’) 
    Clethra is one of those great late summer plants you can’t miss because of its strong fragrance and pure white flower spikes.  Summersweet comes in many cultivars, with white or pink flowers.  ‘Hummingbird’ is just 2.5-3 feet tall and wide and spreads nicely with age.  

  • ‘Annabelle’ Smooth Hydrangea (Hydrangea arborescens ‘Annabelle’) One of the most popular hydrangeas, known for its pure white, massive, globe-shaped flower heads and its ability to light up a shady border.  In recent years, growers have also developed cultivars with light pink blooms

  • Limelight Panicle Hydrangea (Hydrangea paniculata ‘Limelight’) This late-blooming hydrangea has large, upright, pale lime green blooms that eventually fade to a lovely pink.  The shrub is six to eight feet high and wide and makes a great statement when planted en masse.  
    Flower heads are often used in bouquets, fresh or dried.

  • Hybrid Crapemyrtle (Lagerstroemia indica) Large shrub or small tree with bright flowers and glossy green leaves that turn red in autumn. The exfoliating turnk bark remains spectacular throught the year. 

  • Bottlebrush Buckeye (Aesculus parviflora var. serotina) This is a plant you’ll covet if you ever happen to see one in a neighbor’s yard:  it has upright, eight-to-twelve inch long pure white flowers that resemble bottle brushes and large, tropical-like dark green leaves that turn golden yellow in autumn. The straight species flowers in late spring, and variety  serotina  flowers a few weeks later.  It is a large specimen plant that growes eight to twelve feet high, eight to fifteen feet wide.  

  • Waterlily (Nymphaea spp) There are dozens of species of waterlily, known for their large, oval green leaves and slightly fragrant blooms that float above the water.  The flowers come in many shades: pink, blue, purple, pure white and even yellow.  The common North American white water lily often seen in the wild is Nymphaea odorata.
