How Do You Propagate Oxalis Purpurea?

Is oxalis purpurea invasive?

Oxalis purpurea ‘Ken Aslet’ is a bulbous perennial that blooms in the fall and winter with funnel-shaped, vivid lemon-yellow flowers.

They are carried atop velvety, pale green trefoil leaves that are hairy with silver. This plant is easy to cultivate and non-invasive, remaining green in the spring and dormant in the summer.

  1. purpurea, like a number of other oxalis species, is considered a weed in a number of locations throughout southern Australia, including eastern New South Wales, Victoria, and Tasmania, the south-eastern and southern parts of South Australia, and the south-western and western parts of Western Australia.

How do you propagate oxalis purpurea?

Oxalis purpurea is a flowering plant species in the woodsorrel family that is commonly referred to as purple woodsorrel.

It is indigenous to southern Africa, particularly South Africa, but is considered an invasive species on the majority of continents.

It is grown as an ornamental. This bulbous perennial plant produces a few basal leaves and blooms.

The leaf is composed of three hairy, dark green leaflets of varied forms.

Oxalis purpurea is a relatively easy plant to grow via seeds and bulbs.

Bulb propagation

Spring temperatures over 5C (41F) or fall temperatures below 0C (32F) in hardiness zones are the optimal times to grow bulbs.

Planting Dig a hole twice as deep as the existing root ball plus an additional 90-200 percent larger the plant, the smaller the percentage, and fill it with organic debris, humus, and dried leaves.

Place the plant and a small piece of the root ball above the hole, cover it, and avoid pushing the dirt too hard but not too lightly, since the plant may fall into the hole when watering.

Following this, use mulch to retain moisture in the soil and water daily for the following two weeks (best in the morning). Bulbs should be planted 2-5cm deep (1-2 inches).

Seeds propagation

The optimum time to plant Oxalis purpurea is in the spring when the temperature exceeds 5C (41F) or in the autumn when the temperature in the hardiness zone is less than 0C (32F).

Scatter seeds (0.8-1.2 inch) apart on the soil in a sunny to partly shady garden bed.

Fine Gardening recommends sowing the seeds in the spring, when the soil temperature reaches 41F degrees Fahrenheit.

Gently press the seeds into the soil, leaving about an eighth of an inch of dirt around them.

Water the area and keep the oxalis seeds wet until they germinate.

Once germination happens — you will observe green shoots emerging through the ground — water the garden bed regularly throughout the first growing season to maintain moist soil.

Is oxalis purpurea a perennial?

Oxalis purpurea, often known as purple woodsorrel, is a bulbous perennial species in the Oxalidaceae family of wood sorrels.

Native to Southern Africa, this plant has spread throughout Europe as a result of garden imports and has become naturalized in temperate areas.

This species produces lovely funnel-shaped blooms in shades of pink, purple, and white cream with yellow throats and five overlapping petals.

These are around 3-5cm broad and develop during the fall and winter months.

How tall do oxalis purpurea grow?

Oxalis purpurea, most often known as oxalis or wood sorrel, is a Cape of Good Hope native (South Africa). It is a bulbous, stemless perennial that grows to a maximum height of 4-5 inches.

The typical clover-like leaves are composed of three circular, frequently center-creased, green leaflets that are purple on the underside.

Throughout the summer, dark rose, rose pink, violet, or white 5-petaled solitary blooms (1-2″ diameter) with yellow throats develop. Oxalis variabilis is a synonym.

The genus name Oxalis derives from the Greek word oxys, which means “acid,” “sour,” or “sharp,” all of which pertain to the leaves’ flavour.

Is oxalis purpurea edible?

Green leaves are palmately divided into three leaflets, which are arranged at the end of stems. The leaves of the Oxalis genus are three-sided and heart to triangular in shape.

Additionally, the foliage is coated with silky, white hairs.

While Oxalis leaves are edible, they should be taken in moderation due to the fact that oxalic acid can hinder calcium absorption, and those who are prone to kidney stones, have gout, or suffer from rheumatism should avoid them totally.

How do you germinate oxalis purpurea?

In a sunny to partly shady garden bed, place seeds 8 TO 1.2 inch apart on the soil. Seeds should be sown in the spring when the soil temperature reaches 41 degrees Fahrenheit.

Gently push the seeds into the earth, just covering them with approximately one-eighth of an inch of dirt.

Water the space and provide a moist environment for the oxalis seeds until they germinate. Once germination has occurred.

Germination will take at least three to five weeks.

Green shoots will emerge from the soil; continue watering during the first growing season to keep the soil wet in the garden bed.

Why is my oxalis purpurea leggy?

Leggy oxalis purpurea can be due to a number of factors.

Firstly, if the plant has grown too big for its container, it will naturally stretch out in an attempt to reach the light. Thus, transplanting into a pot two sizes larger than it is currently growing in may solve this problem.

Secondly, legginess could be caused by low levels of nitrogen fertilizer or low-nitrogen soils.

Overwatering is another common cause of legginess, so if the plant is not receiving enough water, it will start to grow longer stems in an attempt to gather moisture. Decrease watering levels and the oxalis will begin growing bushier, again.

Too much lights is another cause of legginess and yellowing of the leaves. Oxalis does best with partially shaded sunlight or medium lighting conditions; a full sun environment for too long can burn its leaves.

To solve this problem, move the plant to a shadier location, or if it is too large to move, try installing some tree-filtered or partial light.

Lastly — and probably most importantly — lack of water is one of the most common causes for leggy Oxalis Purpurea plants.

Pests and diseases is another reason your oxalis purpurea may be leggy, or wilting.

How to care for oxalis purpurea?

Oxalis purpurea is a flowering plant species in the woodsorrel family that is commonly referred to as purple woodsorrel.

It is indigenous to southern Africa, particularly South Africa, but is considered an invasive species on the majority of continents.

It is grown as an ornamental. This bulbous perennial plant produces a few basal leaves and blooms.

They thrive well in the following conditions;

These plants thrive in USDA Zones 9-10 under the following conditions:

Soil requirements

Oxalis Purpurea needs medium, well-drained soils that have a neutral pH and good drainage.

Oxalis Purpurea plants grow very well in acidic soils (pH 6.5-7) but the plants will tolerate slightly lower pH soils, but they will not bloom as vigorously or develop as large of flowers when grown in such conditions.

Sunlight requirements

In full sun to part shade, and can spread by running roots and bulb offsets to form colonies in optimum growing conditions.

The best positions give some midday shade from the scorching heat. Low lights makes for an attractive foliage plant but can be grown in full sun if the dry soil is well watered.

Avoid direct summer sun exposure to the foliage. If you are unable to grow these in containers outside, try planting in a sheltered and cooler spot such as under a tree or structure in your yard.

Winter Hardy requirements

They are not winter hardy in the St. Louis region, and should therefore be planted in containers or pots that may be carried indoors during the winter.

In the spring, plant bulbs in pots and move them outside after the latest frost date. Before the first frost, bring pots indoors to a cool, dry place and overwinter dry in the pots or separate bulbs and store in a dry medium.

Water requirements

Maintain regular moisture levels in container soils throughout the growth season.

Reduce watering in late summer when the foliage begins to wither. Make sure you do not overwater Oxalis Purpurea.

Always water when the plants are dry. In summer, a weekly watering is sufficient unless plants are planted in containers that may be moved during the winter.


Repot bulbs in spring. When repotting, use a well-draining potting mixture. A 20-30% ratio of sand or perlite should be used.

Do not use coarse clay as it will clog the drainage hole and make the root system very short.

To minimize root rot and encourage healthy roots, it is best to repot every few years in the life of the plant.

Always water thoroughly after repotting to remove excess soil or excess water can cause roots to rot or rot nearby bulbs or leaves.

How often do you repot your Oxalis Purpurea?

Because the Oxalis Purpurea is reasonably compact, repotting only needs to be done every few years.

Perhaps when the plant has extended to all four edges of the pot or you wish to encourage it to become bushier.

In any event, as long as the compost has adequate drainage, a typical all-purpose compost will suffice.

Before repotting a fake Oxalis Purpurea plant, thoroughly hydrate the soil for approximately 24 hours prior to repotting.

As a result, the risk of transplant shock is reduced. Remove the plant carefully from its original container, taking care not to harm the root system.

Brush away any old dirt that has clung to the root gently. Create a hole large enough to accommodate the root system in the soil.

Place the plant in the hole’s middle and firm the earth down.

Lightly water till new growth develops. This should occur around six weeks after planting.
