Hardy Pecan

Black Gum is a slow-growing ornamental shade tree with a dense pyramidal shape. The foliage is dark green in the summer, and transitions to bright fall colours which include red, orange, purple, and gold. It is commonly used as an ornamental tree in parks and large gardens as a specimen or shade tree.

The small greenish white flowers provide nectar for bees and black tupelo honey is a sought after flavour. The small dark blue fruits which ripen in late summer will attract birds and other animals to your yard. The fruits are edible, but very sour, and are primarily used for pies, flavouring, and drinks. Plant the Black Gum where it will live long-term, as it has a large taproot and does not transplant well.

Hardy Pecan trees are known for their edible nuts that ripen in late autumn. They can be eaten raw or cooked and can be used in a wide range of baked goods. If stored properly in a cool, dry location, they can be kept for up to 6 months in their shell. Trees tend to bear nuts at maturity, which occurs around 6 -10 years. The size and form of this tree also makes it a great shade or feature tree for your landscape.

For nut production, it is recommended that at least 2-3 are planted so that cross pollination can occur. In colder areas it is likely that nut production will be limited, especially in locations with late frosts and shorter growing seasons.

If exposed to high winds, Hardy Pecan is known to lose branches, but these can be used as firewood, or to smoke foods with a hickory flavour. Finding seed or seedlings of this tree is rare in Canada.

Note: plant this tree once. It will not respond well to transplanting.
