For sale is one plant of Black Magic - Colocasia esculenta 'Black'
This water plant is currently growing in a 140mm pot size.
It is posted bare/loose rooted usually with one leaf depending on the time of year, and you need to plant it when you receive it.
Black Magic is a stunning perenial water plant with beautiful heart-shaped leaves, which start out green, deepening to purple-black as they mature.
HEIGHT: Grows to 1.5 metres tall
POSITION: Grow in part shade to full sun in the shallow waters around the edges of ponds and wetlands, 5-10cm deep. Can also be grown in decorative water pot with no hole. In a decorative pot, think of them as a potted plant, growing in water, and then you can grow it on your patio, verandah, balcony etc. However a dish/saucer of water is all you need to sit your pot plant in, as long as you make sure there is always water in the saucer.
FROST: Frost tender. Shelter from cold winds. Goes dormant for winter in southern states of Australia.
CARE: Fertilise in spring with one of Triffid Park’s water plant fertilizer tablets to encourage new growth at the start of the growing season.
Then again at the start of summer, and the start of autumn to encourage healthy growth and green foliage.
FERTILISER: Triffid Park's Water Plant Fertiliser Tablets are available on our Water Plant Sundries page. There are no nutrients in a plastic pond or tub, so these are a definate must when potting your water plants, and for fertilising 3 times per year.
AVAILABLE: Australia wide
Black Magic - Colocasia esculenta 'Black'
When you receive your water plant, it will come to you bare/loose rooted (not potted). You can repot water plants at any time of the year.
During spring, summer and autumn your water plant will arrive with some leaves. During the dormant period in winter, it may have no leaves depending on the variety.
If you are planting it in a pond or decorative water bowl, read the minimum and maximum depth requirements on the label. You will need to pot it into a pot large enough for it to grow, or even a 4 litre ice cream container will do (eat the icecream first!).
Use a good quality garden soil i.e. one that you could grow vegetables in is best - do not use potting mix as it can contain pine bark and other composts not suitable for ponds, as they can release the wrong nutrients which then feed algae.
When planting your water plant, you want the top of the growing tip to be level with the top of the pot. Work out how deep you will need to plant your water plant in the pot so the tip is level with the top, then fill the pot with your soil to where the roots would start. Place one of Triffid Park's Water Plant Fertiliser Tablets on the soil, sit the water plant beside the fertiliser tablet and fill the rest of the pot with your soil to just below the growing tip. Pat down firmly, then place a layer of small pebbels or gravel around the top to stop the mix floating. Take care not to cover the growing tip.
If you are planting into a dam or lagoon, plant straight into the base of the dam. Read the depth information for the water plant and do not plant any deeper than suggested when the dam is at full height or you will drown your water plant.
If you cannot get into the dam and dig a hole to plant the water plant, you can use a tent peg to hold it down.
Most dams will have enough nutrients to feed your water plants during the growing season, but one of Triffid Park's Water Plant Fertililser Tabets pushed into the root system on planting is a good way to get your water plant established.
Yabbies love new water plant leaves, so if you have yabbies in your dam, you will need to place a fine mesh cage around your water plant. The mesh needs to be large enought for the new leaves to grow through, but small enough that yabbies cant get through. Once the water plant is established the yabbies wont be as interested in the older growth.
