TREES & plants. Sweet birch. Sweet birch is an attractive tree for lawns and naturalized areas, with shiny, red-brown bark and yellow foliage.

In my Zone 8B garden sweet alyssum is best suited to the fall, winter, and early spring garden. However, sometimes it remains in the garden year round. It almost seems perennial because seeds are produced that fall to the ground or are carried by the wind to nearby places.ome gardeners reported that sweet alyssum was invasive in their gardens and that volunteer plants reverted to the somewhat gangly species. If this is a problem, select one of the recently introduced sterile types, such as âSnow PrincessâÂ®, a sterile hybrid from Proven Winners that is heat tolerant.
