CANNA BLACK NIGHT- (RHIZOME) TROPICAL foliage !

The Canna 'Black Knight' has bronze foliage, on which superb, blood red flowers with wavy, dropping petals stand out against.
The rhizomes are planted out in the spring, between February and end of May, and offer you magnificent flowers from the summer through to November.
Cannas can stand dry spells, but will be at their best if watered regularly.
Dead head on a regular basis to promote the apparition of new flowers, and staking is necessary for the tallest varieties.

The rhizomes can be planted out directly in your garden, or in pots.

 When to Plant Cannas

• Cannas can not tolerate cold temperatures. Soil must be 60ºF or warmer before planting rhizomes—often the time when folks put tomatoes in the ground. See our Planting Calendar for tomato-planting dates. To determine soil temps, dig a small hole 2 inches deep and insert a thermometer.
• In cold-, short-season areas, start canna rhizomes in pots indoors or in a greenhouse to transplant outdoors at the right time.

How to Plant Cannas

• Space rhizomes 1-1/2 to 2 feet apart to give cannas enough room. Containers need to be at least 18 inches in diameter (per rhizome). 
• Before planting, loosen the soil to a depth of 1 foot, then mix in 2 to 4 inches of compost.
• Dig a hole 2 inches deep and set the rhizome 1 to 2 inches below the soil with the “eyes” (bumps or nodes, which are growth sprouts) pointed up.  
• Cover with 1 to 2 inches of soil. Tamp firmly.
• Water thoroughly, then withhold water for as long as 3 weeks, and watch for signs of growth. Cannas are slow to sprout. Once sprouted, water at least once a week by slowly soaking the area around the roots.
• Full foliage color develops when days are warmer (59ºF or more). Blooms should appear in 10 to 12 weeks.
