Bearded Iris grows well in full sun. Proper soil drainage is important in preventing bacterial soft rot in the rhizomes. Dahlias are other summer flowering bulbs that offer a great deal of variety in the garden. They thrive in full sun or partial shade and prefer moist, well-drained soil. Their many brilliant and rich colors make striking displays that provide an excellent garden backdrop.
Dahlias also have variable heights.
The 'Dwarf Border Jewel' works well for borders and garden spots needing to be filled with short plants. Dahlia flowers can be rather exotic looking, like the 'Bertha Shane' lavender blend. It looks like a piece of sea coral found in the ocean. In a garden, this particular cultivar would provide interesting texture contrast amongst flowers. Other cultivars, like 'Starry Night,' have bicolor petals offering yet more flower diversity in your summer garden.
