Do purple tree collards taste good?
Our purple tree collards are planted along the south side of our house and so far they’re thriving. Tree collards even taste better after a frost—the cold tends to sweeten the leaves a bit. They do taste good. We use them a lot as cooked greens but we also chop them up and use them with other greens in salads.
What does it mean when a plant turns purple?
Other Causes for a Plant with Purple Leaves. If you have a plant with purple leaves, it may also be due to elevated levels of anthocyanin, which is a purple colored pigment. This pigment builds up when a plant becomes stressed and normal plant functions are interrupted.
What does Collard Greens look like?
Collards are erect, branched plants with thick stems and irregularly lobed dark green leaves with long petioles. The plant produces clusters of small yellow flowers on racemes. Collards can reach 1 m (3.3 ft) in height and are usually grown as annuals, harvested after one growing season.
Can you eat collards that turn purple?
You can eat these leaves raw in salads, in sandwiches or in wraps. As an evergreen plant, the leaves will be available to harvest all year round, and they're a bit sweeter in the winter after a frost. This makes them a fantastic winter green in milder climates.
Why do green leaves turn purple?
The purple color in leaves comes from pigments called anthocyanins. These pigments also give many red- and purple-colored fruits and flowers their color, as well as tree species that turn a reddish color in autumn.
Why do vegetable leaves turn purple?
The purple color is caused by anthocyanin, a harmless, water-soluble pigment that is exacerbated by sun exposure. When the developing heads are exposed to sun and heat, they can turn purple. Extreme conditions, such as heat, freezing temperatures, or drought also can cause loose heads.

What does phosphorus deficiency look like?
Phosphorus deficiency tends to inhibit or prevent shoot growth. Leaves turn dark, dull, blue-green, and may become pale in severe deficiency. Reddish, reddish-violet, or violet color develops from increased anthocyanin synthesis.

Description
Collards, Brassica oleracea var viridis are herbaceous annual or biennial plants in the family Brassicaceae grown for their edible leaves which are consumed as a vegetable. Collards are erect, branched plants with thick stems and irregularly lobed dark green leaves with long petioles. The plant produces clusters of small yellow flowers on racemes.
Uses
Collards leaves are usually consumed after cooking and are eaten as a leafy green vegetable.
Propagation
Basic requirements Collard greens are a cool season crop that grow best in cool, moist conditions. The plant will grow best at temperatures between 4 and 21°C (40–50°F) allowing it to be grown in both Spring and Fall. Collards are very hardy and will tolerate frost.
Growing and Harvesting Purple Tree Collards
While our tree collards started out small, they’ve grown quite large! So much so that they even help shade part of our house. Soon I will have to keep them trimmed so they don't block our window!
Getting Started with this Great Perennial Vegetable
I just love how big the leaves can get on these great perennial vegetables!
Why Are Plant Leaves Turning Purple?
When you notice a plant with purple leaves rather than the normal green color, it is most likely due to a phosphorus deficiency. All plants need phosphorus (P) in order to create energy, sugars, and nucleic acids.
Leaves Turning Reddish Purple in Color
Leaves turning reddish-purple in color is most often seen in corn crops. Corn with a phosphorus deficiency will have narrow, bluish-green leaves that eventually turn reddish-purple. This problem occurs early in the season, often due to cold and wet soil.
Other Causes for a Plant with Purple Leaves
If you have a plant with purple leaves, it may also be due to elevated levels of anthocyanin, which is a purple-colored pigment. This pigment builds up when a plant becomes stressed and normal plant functions are interrupted.
Proper Care
Many plant growth issues stem from not meeting a plant's cultural requirements, including proper placement, light exposure and irrigation practices. When a cultural requirement is lacking, plants exhibit symptoms similar to those of nutrient deficiency or disease. Stretched and spindly collard plants with low yields signify inadequate light levels.
Nutrient Deficiency
Collards are primarily grown for their large, edible leaves, and require a steady supply of nitrogen to produce a continuous flush of growth. Without sufficient nutrient availability, growth will be stunted or result in pale green or yellow foliage. Consider using a slow-release fertilizer, which feeds the plant throughout the growing season.
Pests
In the home garden, collard greens face two major pests: aphids and imported cabbageworm. Aphids are attracted to the newest growth, sucking juices out of the tender leaves and causing them to become stunted. Look for groups of small green insects clustered on the undersides of leaves, and remove by spraying with a hose.
Diseases
Though uncommon in healthy garden soil, disease occasionally accounts for poor plant growth in collard greens. Fungal pathogens such as clubroot, phytophthora root rot and verticillium wilt produce symptoms of stunted growth and yellowing of lower leaves.
Temperature
Among the hardiest vegetable plants, cabbage can survive cold temperatures and even a bit of frost. Cold weather, though, may cause some cabbage leaves to turn purple. The discoloration isn't permanent and does not indicate a problem with the plants. The purple color should go away as the weather warms.
Nutrient Deficiency
Cabbage plants' leaves may turn purple when the plants don't have enough nutrients. The deficiency is caused by a lack of fertilizer or poor soil, and, usually, the problem can be corrected by feeding the plants.
Deficiency Correction
Magnesium sulfate can correct or prevent a magnesium deficiency, and ammonium-nitrate fertilizer works against nitrogen deficiency. Fertilizing cabbages at the time they are transplanted produces the best results. Dig a shallow furrow about 3 to 6 inches from a row of cabbages.
Soil pH
The pH level of your garden's soil is a measurement of how alkaline or acidic it is. If the soil is too acidic or too alkaline, then cabbage plants may respond by turning purple. Cabbages grow best in soil with a pH of 6.0 to 7.5. Determine your soil's pH level with a pH-testing kit, available at plant nurseries and hardware stores.
Red Cabbage
Not all cabbage leaves turn completely green when mature. Some, called red cabbages, develop a purplish hue. They often have green outer leaves and a purple head. Red cabbages grow the same as green varieties; the only difference is their color. "Ruby Ball" and "Red Meteor" are two common red cabbage varieties.
